Which friend can help me translate this passage about rolling mills into English?

At present, the single-station and double-station types of open training board factory are widely used to produce plates, which are suitable for Russian and foreign factories.

One of the only mills still in operation is Lauter's. This is a three-high mill, with larger diameter and smaller idler rollers driven at the top and bottom. The barrel length can range from 1800 to 4000mm.

Steel plates with a thickness of 4 to 25 mm are usually produced on these Lauter mills with only three heights. These rollers have the following dimensions: roller length 1800 to 3000 mm, top and bottom rolling diameters 700 to 850 mm, middle roller diameter 450 to 550 mm, and the ratio of roller length to diameter is 2.5 to 3. The rolling speed ranges from 2.5 to 3.5 meters per second. The coil is usually powered by an AC motor through a reduction gear and the end position of the bird wing; The flywheel is installed on the end shaft of the driving bird wing with reduction gear.

The only Lauter-style factory with three heights is often quite modernized. This may require them to rebuild into a two-station mill with four-high finishing positions.

The only rolling mill with three heights is widely used to roll wide plates and armor plates. The length of the roll body of the largest four-high vertical rolling mill is 5230mm. The working roll diameter is 1 100 mm, and the standby roll diameter is 1650 mm. ..

The newly developed medium plate mill is a two-station tandem unit. You are a finishing post such as rough grinding. The width of these rollers ranges from 1500 to 2600 mm.

Because the plate is rolled from the flat plate with the shed in the rough grinding position at the finishing position of these rolling mills, the plate with better quality is obtained, and the product life of the roller is prolonged, so the frequency of replacing the roller is reduced. According to the design of coiling position, double-stand vertical rolling mill can be divided into: 1) three-roll Laut finishing position, 2) two-roll rough grinding position and three-roll Laut finishing position, 3) two-stand rough grinding four-roll finishing stand and 4) four-roll rough grinding finishing stand.

When using the three-roller rough grinding position, the application of the two-roller twisted rough grinding position has certain benefits, such as: a) no need for a heavy tilting table, b) larger bite angle, so higher inclination can be applied, and c) reduced idle time between butchers.
