PLC control adopted; 2)Full hydraulic pressing down, the thickness is controlled by AGC automatically. The hydraulic AGC system adopts 2-stage computer controls, additional to the functions of constant roller seam, constant rolling force and thickness monitoring, it also bring tension AGC, etc; 3)The rolling mill has the functions of deviation rectifying when pressing down, work roller curve rolling positively and negatively, as well as belt shape controlling methods of mid roller positively rolling, mid roller horizontal move pre-setting, cold treating in stages, etc. The thick-difference can be guaranteed controllable by the techniques of heavy rolling force, heavy rolling force moment, heavy tension rolling methods,; 4)CPC automatic centering function is granted to uncoiler, besides, the recoiler can carry out operations of automatic reeling up (EPC), accurately stopping, circle number counting, automatically decelerate and stop when belt rear passing through; 5)The work and mid rollers can be replaced quickly; 6)Overload and belt breaking protections, emergency stop mechanisms are introduced into rolling mill electrical system. Both the master mill and the recoiler have the capabilities of automatically decelerating, actually stopping and belt circle number counting; 7)Digital indicators can exactly reflect the mill speed control, uncoiling and recoiling speed and tension control; 8)The rolling line level can be fast and automatically adjusted; 9)The rolling mill bearing lubricated by oil fog; 10)Interlocking mechanism adopted in the producing processes, failure alarms are controlled by PLC, an automatic production is therefore realized; 11)The mill is also equipped with process parameter pre-setting, procedure parameter and key equipment parameter examining, indicating and alarming systems, ensuring failure self diagnose, alarm, and belt breaking automatic protection.
