Summary of sintering workshop work

A summary is a written material that analyzes and studies relevant situations within a certain stage and makes guiding conclusions. It can motivate people to work hard. Let us learn to write a summary together. How should we write a summary? The following is a summary of the sintering workshop work that I have compiled for you. Welcome to read and collect it. Summary of the work of the sintering workshop 1

In the work in 20xx, the workshop adhered to the working idea of ??"focusing on internal work and serving the blast furnace wholeheartedly", with the goal of "producing high-quality and high-yield sinter", and With production as the center, we implement and improve various systems, strengthen internal management, strictly control process operations, and implement full-staff management of equipment, so that all work can proceed in a solid manner and develop steadily.

1. Do a good job in basic work and strengthen internal management

Adhere to the regular workshop meeting system. A regular workshop safety production meeting is held every Monday to analyze the production situation of the previous week, reflect the existing problems in the production process, convey the relevant instructions and spirit of the company and the factory, and arrange the next stage of work, aiming to strengthen internal communication and assurance in the workshop The timeliness of uploading and issuing file instructions.

Actively cooperate with various functional departments to carry out standard implementation inspections, and conscientiously implement the rectification of unqualified items; at the same time, the workshop also ensures the implementation of system documents through self-examination and self-correction, and conducts self-examination every two weeks. It mainly checks employees' proficiency in job responsibilities and three major regulations, as well as the standardization of job records.

Strengthen personnel management, establish a squad leader responsibility system, and focus on team building. Employees have stable minds and show a certain degree of enthusiasm. They actively participate in corporate cultural and sports activities in their spare time. For example, Lan Zhou, a shuttle cloth worker, won the championship in the company's "Please give me the results" competition. The phenomenon of high employee mobility has been effectively controlled, with 17 employees moving throughout the year; the team of old employees is relatively stable and has developed into the mainstay of the workshop.

Cooperate with various functional departments to provide employee training. On average, each employee received more than 10 training sessions on safety, technology, and equipment throughout the year, and the employees' own quality and operational skills have been further improved.

2. Strictly control process and technical operations to improve product quality

First, strengthen the control of moisture. The water inspection post is required to strictly implement the "three diligent, one accurate" operating policy, frequently observe the fluctuation of the moisture particle size of the mixture, strengthen contact with the sintering, granulating, and mixing rooms, adjust the moisture in a timely manner according to the incoming materials and production conditions, and strengthen The mixed granulation effect improves the air permeability of the material layer and stabilizes moisture during the sintering process.

Secondly, the fire-watching post strictly implements the operating policy of "low carbon, thick laying, slow turning, and stable", and strengthens operations such as laying, ignition, and end point control to ensure stable water and carbon during the sintering process, so that the team can Production has stabilized at a relatively high level.

Third, balance the use of internal circulation return minerals. Pay close attention to the amount of returned ore during the production process. When production is stable, each shift is not allowed to increase or decrease the amount of returned ore at will. When production fluctuates, it is necessary to predict changes in the amount of returned ore and take adjustment measures in a timely manner. .

Fourth, strictly control air leakage. Post workers are required to strengthen inspections of air leakage points and take effective measures such as blocking, repairing, and adjustment to deal with them in a timely manner. Before each maintenance, the entire exhaust must be comprehensively inspected, and the air leakage problem is treated as a key issue during each maintenance.

With the joint efforts of various departments and workshops, the economic and technical indicators of the entire factory reached new highs in 20xx. As of November, our factory has produced 1,804,194.43 tons of sinter. The sintering machine utilization coefficient is 1.83t/m2h, an increase of 0.05t/m2h compared with the same period last year, and continues to lead the average level of domestic peers. The FeO stability rate was 95.33, a decrease of 1.34 compared with the same period last year; the drum index was 74.86, an increase of 0.37 compared with the same period last year; in terms of energy consumption, the unit fuel consumption was 60.66Kg/t (non-standard coal), which was 1.34 lower than the same period last year. Compared with the same period last year, the electricity consumption decreased by 4.46Kg/t, and the electricity consumption was 34.11Kwh/t, which decreased by 4.70Kwh/t compared with the same period last year.

It can be seen that the economic and technical indicators that this workshop is mainly responsible for, except FeO stability rate, have made great progress to varying degrees.

3. Promote full-staff management of equipment to ensure operation rate

First, formulate and improve relevant systems based on the actual situation of the workshop to make up for management loopholes. Implement the "Shift Responsibility System for Equipment Maintenance in the Sintering Workshop", divide the equipment in the workshop into teams, and assign equipment management responsibilities to teams and individuals; implement the "Equipment Inspection System in the Sintering Workshop" to specify the equipment inspection time in detail The content and assessment details further refine the equipment inspection work and help employees improve their equipment inspection level.

Secondly, make arrangements for planned maintenance. Actively contact the inspection station before each maintenance and propose the items that need maintenance and related requirements. Seize this favorable downtime to solve equipment problems, and organize employees to replace belt protectors, rollers, grates; lubricate reducers, electric drums, bearing seats and other parts; Clean the accumulated minerals or sticky materials in the machine, lower hopper and ring cooler.

Third, do a good job in belt supervision, processing and replacement. As the sintering output pressure increases and the cooling effect of the ring cooler becomes worse, the tape machine of the finished system frequently breaks down and the service life is shortened. This is also a major focus and difficulty of my workshop this year. First of all, the on-duty foreman is required to pay close attention to the operation of the belt under his jurisdiction during the shift, and promptly discover and report problems. Key belts such as Z8-1, LS-1, and LS-2 are inspected personally by the workshop director every day. It is necessary to predict the life of the belt, negotiate with the inspection station in advance, properly arrange maintenance in a planned manner, and try to avoid temporary shutdowns to deal with the belt.

With the joint efforts of various departments and workshops, the downtime of various equipment failures and process downtime have been controlled to a certain extent. As of November, the entire plant's operation rate was 93.99, basically completing the target. For the sintering workshop, as of November, the system was down for 14 hours and 42 minutes due to the replacement of trolleys and grate bars, an average of 80 minutes per month, accounting for 0.18 of the calendar time; the system was temporarily shut down to repair or replace belts 34 times, An average of 3.1 times per month, the resulting system downtime was 42 hours and 16 minutes, accounting for 0.53 of the calendar time; the lower hopper or the cylinder distributor caused material jamming and jamming 27 times, an average of 2.5 times per month, by The system downtime caused by this was 8 hours and 40 minutes, accounting for 0.11 of the calendar time; belt jamming, crushing, slipping and other faults caused the system to shut down 20 times, an average of 1.8 times per month, and the resulting system downtime was 7 hours and 4 minutes, accounting for 0.10 of the calendar hour.

4. Implement safety and environmental protection work to protect production

In terms of safety, we first provide safety education for new employees, especially on-site safety operations. Secondly, conscientiously implement the weekly safety day activity education to ensure the implementation of personnel time, location and content. Safety production mobilization must be conducted before the third shift meeting, so that employees can maintain a high degree of safety vigilance at all times. Fourth, we must do a solid job in safety inspections and hidden danger rectification, and organize safety inspections once a week, covering the entire workshop jurisdiction and involving all personnel on duty. Each hidden danger rectification project is implemented by a team or a dedicated person, without delay, and with emphasis on practical results. There were more than 30 hidden danger rectification projects in the entire workshop throughout the year, and safety accidents were "six to zero".

In terms of environmental protection, we will comprehensively promote clean and civilized factory work. Organize employees to "declare war" on the dead corners of the entire workshop, clean up all corners, belt corridors, rest rooms and other dirty places within the jurisdiction of the workshop; conscientiously implement the rectification projects of the company or the production safety and environmental department, and try to solve problems that can be solved on duty , arrange for the deputy shift to deal with problems that cannot be solved on duty; pay attention to cultivating employees' awareness of cleanliness and civility, help employees establish good hygiene habits, and prevent littering of cigarette butts or smoking; strictly pay attention to post hygiene to ensure that the floor is clean and the equipment surface is free of dust and Items are neatly arranged. After a year of hard work, great progress has been made in cleaning the factory. Many historical sanitation blind spots such as the factory color panels, belt corridors, inner and outer rings of the ring cooler, and double preheating furnaces have been cleaned up, giving the entire workshop a completely new look.

5. Work Outlook for 20xx

Looking back on the work of this year, in general, the implementation of various tasks has been relatively in place and certain achievements have been achieved, but there are still some problems. , such as unstable shift output, high mineral return rate, poor ring cooling effect, and many belt failures in the finished product system. Especially as the main equipment ages, how to ensure the operating rate when spare parts cannot keep up; as the pressure on blast furnace materials increases and the company's indicators improve, how to continue to stabilize production, maintain quality and reduce consumption, these will all be The focus of my workshop's work in 20xx. We look forward to another good harvest year in 20xx. Summary of work in the sintering workshop 2

In 20xx, under the correct leadership of the sintering plant, the safety production work in the sintering workshop was fully implemented and the various decisions and deployments of the sintering plant regarding safety production were fully implemented. Focusing closely on the work requirements and priorities of "safety production", we adhere to the policy of "safety first, prevention first, comprehensive management", continue to carry out in-depth rectification work on safety production, focus on team building, and strengthen detail management , insisting on continuous safety inspections with daily inspections, mutual inspections, and weekly joint inspections as the main methods. Pay attention to the needs of employees' positions, take into account the summer, flood season, autumn and winter seasons that are not conducive to production, focus on special management of accident-prone points on site, strictly control and reduce the "three violations" of employees, and constantly improve the work environment of workshops and teams. Basic safety management work ensures that production proceeds in an orderly manner. With a highly responsible attitude towards the life and property of the company and employees, we will carry out in-depth safety inspections, governance and publicity and education work and deploy the work goals for 20xx.

1. Establish and improve a safety management network and conscientiously implement the safety management system.

In order to ensure the smooth development of safety work, managers at all levels in the workshop use the regular safety meetings of the team as a breakthrough point to assist the team to carry out safety activities, improve the safety management level of the team, and form the overall safety management of the workshop. A security management network that extends horizontally to the edge and vertically to the bottom. Everyone participates in safety management and everyone is responsible for safe production, gradually reaching the consciousness of "I am responsible for my safety, and I am responsible for his safety", laying a solid foundation for safety management work. We also strive to achieve "four no harms" to employees during the production process and conscientiously implement various safety management systems formulated by the company and branches.

2. Strengthen employee safety education and training and continuously improve employee safety awareness.

1) The workshop started with new employees entering the factory. The workshop trained 35 new employees throughout the year, all of whom completed three-level safety education as required, and identified teachers and mutual insurance recipients, focusing on Workshop process production status, hazard source identification, job operation skills and safety operating procedures training to ensure that the safety education rate of new employees reaches 100, while ensuring the effectiveness of training.

2) This year, the workshop organized safety training in various forms every quarter. Regular safety meetings were held in the workshop and each operating area every week to summarize and comment on the safety work in the workshop and educate

Employees follow safety procedures. Throughout the year, fire watchers and fire watch squad leaders were organized to participate in more than 10 safety trainings such as air respirator wearing and use training, gas emergency emergency plan drills, fire protection knowledge training for all employees, and examinations were archived and assessments were implemented for those who failed. .

3) During the safety month, the workshop hung safety warning signs at hazard sources, posted safety propaganda slogans in eye-catching locations, replaced more than 30 unclear warning signs, and at the same time inspected the fire hoses at the posts. In order to check and replace, 15 water hoses were replaced to improve the prevention ability of the post and avoid the occurrence of safety accidents.

3. Strengthen on-site management and resolutely stop the "three violations" phenomenon.

1. Safety inspection and hidden danger investigation are management methods to avoid accidents. Joint inspections are organized regularly in the workshop, and managers and safety officers conduct on-site inspections from time to time every day, and problems are discovered and dealt with in a timely manner; all employees participate Investigate hidden dangers, rectify the discovered safety hazards in a timely manner, and formulate temporary measures for those that cannot be dealt with on the same day to ensure that no problems occur. The person responsible is responsible for implementing the rectifications on schedule, and reports are reported to the Safety Department for filing.

In 2012, *** organized more than 40 joint workshop inspections, and found more than 300 safety production projects and more than 90 hidden danger inspection projects, including the replacement of 14 various gas pipeline valves, the replacement of 1.2-meter gas pipeline rubber compensators; There were more than 60 violations, and assessment and education were implemented for all of them, and notices were issued and communicated to all employees.

2. Continue to strictly implement safe operation systems such as "approval of hot work" and "use of maintenance operation cards" to prevent illegal command and illegal operations. During the maintenance period, maintenance safety procedural measures are strictly implemented, and the specific person in charge of safety is designated for the project to ensure the safety and smooth progress of the maintenance.

3. In order to prepare for the review and acceptance of the standard implementation, the workshop organized and organized learning for employees on the key contents of the two systems and further improved the awareness and emphasis on the implementation of the standard, and has successfully passed the acceptance inspection.

4. For the five-proof work in winter and summer, the workshop should arrange early and take early action according to seasonal changes, grasp one level at a time, assign responsibilities to people, and complete the cleaning of the grating strips of the main machine and the fabric processing of the main machine in advance. Install axial flow fans for cooling and insulation of various water pipelines on site to ensure safe and smooth production on site.

5. A total of 45,230 yuan of special safety funds were invested throughout the year, focusing on improving the safety infrastructure in the factory area to ensure the smooth progress of safety work in our workshop. We have made serious rectifications to the requirements put forward by the Safety Department of the head office.

1). Modify the bridge guardrail of the host trolley and install hinged door openings on both sides to ensure the safety of employees during operation.

2) The infrastructure of the gas system was further improved. According to the requirements of the safety department of the branch factory, the 8-hour inspection on September 5 was mainly carried out on the DN600 butterfly valve and DN1200 electric butterfly valve of the gas pipe in the workshop. The replacement and water exchange of the 008# water trap and the replacement of the DN600 blind plate rubber ring ensured the normal operation of the gas pipeline network in winter.

3) Replace two pull-rope switches on the 8# belt to ensure there are emergency power-off devices on both sides of the belt, which effectively improves the safety performance of the belt system.

4) Two insulating rubber sheets were installed under the power distribution room and operation box in the main control room, which effectively reduced the probability of electric shock accidents and ensured the safety of electricity for employees.

5). Add 5 wall fans and 1 air cooler to the post room and main control room. Ensure the safety of employees during the summer.

6) The annual inspection of the CO detection device was completed, and unqualified products were eliminated to ensure that the CO concentration monitoring at the production site is accurate, true and comprehensive, and to avoid gas poisoning accidents.

7) In order to ensure the safety of hoisting operations, the steel wire rope buckles and reverse chains used for maintenance and main engine cranes and cranes were replaced and repaired. More than 10 wire rope buckles were replaced and the reverse chains were repaired. 12.

8) During the safety supervision of the maintenance site in the third quarter, *** discovered 16 problems, all of which have been rectified on site. In order to strengthen the management of inspection personnel and avoid the occurrence of safety accidents, we have further tightened the implementation of safety measures, increased penalties for illegal operations, and gradually improved the safety management of the inspection site to ensure the safety of the inspection process.

4. Strengthen environmental governance and improve the working environment of employees.

In terms of occupational health, strict operating procedures and conscientious implementation of occupational health and safety management system standards ensured that the external audit work was successfully passed. The improvement opinions raised by experts during the external audit were actively implemented and rectified, further improving the system. run. At the same time, an ash room was built at the dust removal area at the tail of the machine, which solved the problem of secondary dust on site. In addition, the cleaning holes of the dust removal pipes at various points in the batching room were modified, and all the original plug-type iron retaining irons were replaced. In order to fix the flange holes with bolts, the loss of air volume is avoided. And further strengthen the inspection and adjustment of the air volume of each dust collection port and the opening of the gate valve. Reasonable use of the dust suppression effect of each water pumping point effectively reduces the dust concentration at the post, effectively protecting the health of employees.

In addition, the workshop strictly followed the requirements of the branch, distributed labor protection supplies on time and in full, strengthened daily inspections, and urged employees to wear them as required. In early September, 58 people working in dust, high temperature, gas and other positions in the factory were organized to participate. I passed the physical examination organized by the Safety Department and found no occupational diseases. The sintering workshop environment is relatively weak. The workshop has formulated the "Sintering Workshop Environmental Management Plan" and planned more than 10 projects for environmental management in the workshop. After approval by the factory director, the management will be carried out according to the plan and schedule. The main projects

(1) Paint the exterior walls of ingredients, machine head dust removal, first mixing, second mixing, cold screening and other parts, lay the floor, and paint the walls.

(2). Three new post rooms and three team warehouses (small trough, cooling zone, and return corridor below) were built in the workshop to solve the problem of employees’ working environment and material management.

(3). More than 20 flower ponds and tree pits were built on site, and more than 300 flowers and trees were planted to improve the greening of the factory area.

(4) Modification of the cold machine tail, return machine head, and 3# dust removal pipe with machine head has greatly increased the dust absorption rate and improved the working environment.

(5) Seal each corridor and install the missing glass in each section. Return to the corridor to seal the composite board, do the batching room, dust removal at the tail of the machine, install more than 10 heating units in one unit, and various pipes inside the workshop. Road insulation and other insulation work were successfully completed, laying a solid foundation for safe production in winter.

(6) From June to October, the main sewer inside the workshop was thoroughly cleaned to ensure the smooth drainage of accumulated water on site. Through the rectification of the above projects, the on-site operating environment of the workshop and positions has been greatly improved, and the work enthusiasm of the positions has been fully mobilized.

5. Insufficient work.

1. Although the workshop has made great efforts in safety management and on-the-job safety education, omissions still occurred. During the maintenance on February 13th, Zhang San, a batching post in class B, was dusting the machine head and cleaning the ash bin. He accidentally fell into the ash bin and burned his hands and feet. In June, Li Mei, the supervisor of shift B at 4 o'clock, showed signs of heat stroke, and two minor injury accidents occurred throughout the year. In terms of personnel management, disciplinary violations such as sleeping on duty, skipping work, playing with mobile phones, etc. also occur from time to time. The workshop will pay a total of 4,860 yuan for those who violate disciplines.

2. In winter, pipeline insulation work is not implemented in place, resulting in some pipelines in the workshop that are not insulated and have dead ends, which affects normal use. This is mainly reflected in insufficient workshop management and inadequate professional daily inspections.

3. There are still certain gaps in basic safety management, such as incomplete basic accounts, incomplete employee transfer education, and delayed replacement of expired fire extinguishers. The workshop should strengthen basic management and improve various basic tasks in future work, so as to achieve a new improvement in basic safety work.

4. There were situations where rectifications were not made in a timely manner during the investigation of safety hazards, and assessments were implemented for teams that were lagging behind in rectifications.

5. There are dead corners for sanitation at the site, and high-altitude pipe supports cannot be cleaned in time.

6. Safety work plan for 20xx.

In order to ensure safe production in 20xx without accidents and fully understand the importance and urgency of safety work, on the basis of summarizing the safety work in 20xx, we formulated key safety tasks in 20xx:

1. Comprehensively implement the production safety responsibility system, take responsibility step by step, check at all levels, and conscientiously implement the safety management system.

2. Focus on key points, continue to deepen the special rectification of safety hazards, organize regular safety inspections, increase on-site inspections, and nip hidden dangers in the bud.

3. Strengthen the training, learning, publicity and education of post personnel, improve employees’ safety awareness, continuously improve the accident handling capabilities and emergency response skills of the post, and comprehensively promote the smooth and orderly progress of safe production.

4. Adhere to the policy of “prevention first, combined with prevention and treatment”, monitor employees’ occupational health, issue labor protection supplies on time, check the use of labor insurance for employees, and strengthen the maintenance of dust collectors and the management of the on-site environment. , further improve the working environment of employees and prevent the occurrence of occupational diseases.

5. Strengthen the safety management of external construction personnel to ensure the personal safety of external personnel and factory employees.

6. Continue to carry out on-site environmental management work to improve the working environment of on-site positions. The main projects include: rectifying the dust problem at the refrigerated tail section.

7. Continue to strictly implement safe operation systems such as "approval of hot work", "use of maintenance operation plates" and "maintenance programmed safety measures" to prevent illegal command and illegal operations. Maintenance
