1. Brief Introduction
The 850mm five stand tandem cold rolling production line is controlled by mechanical and hydraulic pressure, and the control is flexible, stable and controllable. The first four frame for all four and combined with tension sensor and bending roller plate thickness control and five stand for six and intermediate and throbbing and roll bending of plate increased controllable means maximum guarantee the accuracy of the board. In the entrance of the rolling mill is equipped with electric power in place, S roll leveling and other equipment, hydraulic cutting, manual welding machine and screw sets and other equipment, to achieve a continuous rolling, improve production efficiency, improve production capacity.
2.Unit level
