1. The 20-high cold rolling mill belongs to the high-precision equipment, in which the crown adjustment of the cold rolling mill shape belongs to the precision. For many years, it has been a pain point in equipment manufacturing in our country, only relying on imports. Our company independently developed "servo crown control system" has been equipped with more than 20 cold rolling mills at home and abroad.

2.The technology and equipment can automatically eliminate the gap between the roll system and the stand of the rolling mill, and greatly improve the stiffness and accuracy of the pass. When the rolling mill has no clearance, i. e. zero clearance, the position of each backing bearing can be adjusted by hydraulic servo system and closed loop to meet the requirement of adjusting the concave and convex flatness.
