What exactly does this mill model mean?

Hot-rolled strip mill is named after the length of roll body, and the length of roll body is above 9 14mm, which is called wide-band steel mill. The length of work roll of finishing mill is 1700mm, which is called 1700mm strip hot rolling mill. The mill can produce strip coils with a width of 1550 mm. ..

Therefore, 900 is the length of the pinch roller,

Automatic strip thickness control system (AGC) is an important factor and means to control strip thickness. In practice, it is found that the load and response characteristics of electric AGC can not adapt to the working conditions of large rolling pressure and high speed rolling. The hydraulic system has fast response and high control accuracy!

The hydraulic system is used to adjust the roll gap and realize the automatic control of strip thickness (AGC hydraulic control), which is different from AGC electrical control in that the adjustment mode of roll lifting is different when changing rolls. Hydraulic AGC has the characteristics of fast response speed, fast screw down speed, high precision of roll gap setting, simple control system and high precision of strip thickness.
