Constant rolling force control system（AFC）、Automatic elongation control system（AEC）,Now has become one of the necessary technology to produce high quality plate and strip，To increase the rate of finished products and raw material saving and Convenient operation and so on Can play an important role.The system has high response speed, high control precision, high reliability, perfect system protection ability and fault diagnosis ability.The system fully meets the thickness control of single machine or multi frame flat machine. The system can also be based on the situation of the equipment and the requirements of the rectangular options.

Our company research and design of the Skin pass mill / Planisher design of the control system has been running in the factory in Zhejiang, Shandong and other places, but also exported to Vietnam. Mill rolling force fluctuation is less than ±1 ton, greatly reduce wrinkling and breaking of belt, constant extension rate control precision can reach ±0.1, greatly improves the plate yield, improve the product value.
