How much does it cost to cut a 230mm thick steel plate?

It mainly depends on the equipment used. Generally, CNC flame cutting is used to cut medium-thick steel plates.

The cost is mainly based on gas consumption, mainly acetylene, propane and natural gas. Among them, acetylene is the most expensive, and the hourly cost of cutting a 230MM plate is about 140 yuan. Now industrial gas is replaced by new energy. According to Xinhuanet, Beijing, September 22, a new green distributed gas supply for industrial cutting that can replace acetylene, is energy-saving and environmentally friendly The system was successfully developed and put into use by Beijing Jiangtan Technology Co., Ltd. after 12 years. If you use this cutting method, the cost is about 16 yuan per hour.

The most widely used traditional industrial gas is acetylene (carbide gas). Since its introduction in the 19th century, it has been used for metal cutting and welding. It has a history of more than 100 years. However, acetylene has shortcomings such as complex production process and high production cost; low safety factor during production and use, easy to temper and explode; high energy consumption, high emissions, and serious pollution.

In recent years, countries around the world are replacing acetylene with propane, propylene, natural gas, petroleum gas and other gases. Our country began to promote acetylene gas alternatives in the early 1990s, mainly propane (liquefied petroleum gas). Later, it was proposed to develop a new industrial gas production concept that is safe, stable, energy-saving, emission-reducing, and environmentally friendly.

According to Qiu Yunhao, chairman of Beijing Jiangtan Technology Co., Ltd., at the on-site display and press conference of new industrial gas held in Beijing recently, the production process is like this. Our Qiangtan Technology is committed to research and development, production, A new energy technology company that integrates sales and sales, now the company has equipped our flame cutting machine tool with an air supply system. Use water as fuel. Production costs can be greatly reduced. Artificial. It is used for emergency delivery and is very safe. Including cutting quality and speed, it is also a great improvement compared to the traditional one.

Since 2014, China Energy Construction Group, China Fifth Mining Group, including Beijing, Shanghai, Hebei, etc. have successively used new energy for operations.

Advantages of using water instead of traditional gas

Energy saving ~ We mainly do research on hydrogen energy. Our company invented this gas supply system, which produces a mixed gas of hydrogen and oxygen, which can It can replace traditional cutting gas such as acetylene and propylene, but its low cost and energy saving are 85% of traditional fuels. Production can be achieved with ordinary tap water.

Safety~ It is a pressureless gas, ready for use, completely solving the explosion risks and dangers of traditional propylene acetylene bottles.

Environmentally friendly~ The raw materials are water and electricity, water turns into fire, and after the fire is completed, it turns into water. It has zero carbon emissions and zero pollution. Unlike traditional fuels, which release a large amount of harmful gases and cause physical and mental harm to employees~

It does not produce any waste gas or residue, and the cutting effect is obviously better than that of acetylene. It has fast preheating and cutting speeds, smooth and clean cut surfaces, no carbon deposits, no hardening, no slag hanging, and is easy to clean, which can reduce tool wear and can also cut cast iron. The product solves the problem of being able to cut but not weld with similar gas-fired products. It not only has good welding and shaping, but can also be used for sintering, smelting, drilling, baking, straightening, continuous casting and water-containing operations. The most important thing is that it will not burn without an open flame and will not return. fire.

Workers' on-site demonstration of the cutting effect showed that the explosion limit range of this product is extremely small (1.3%-7.3%), and the maximum flame temperature can reach 3450°C. It is non-toxic and non-polluting. Only one bottle is used. Equivalent to more than 8 bottles of acetylene. The experiment also shows that the energy saving and emission reduction effect of using new industrial gas is extremely obvious.

It is reported that this new type of industrial gas has been actually used in the Sixth Aerospace Institute and other units, and the effect is remarkable.
