Brief Introduction
The 550mm 5 stand tandem cold rolling line adopts the pressing mode of the mechanical press, the control is flexible and stable. The three racks are all four rollers and combined with the force sensor to realize the control of the thickness of the plate. In the mill at the entrance with a shearing machine, manual arc welding machine and live sets, such as equipment, endless rolling process, improve production efficiency, improve productivity.
