热轧卷取机变张力轧制改造实践

Modification of Variable Tension Rolling on Coiler of Hot Rolling Mill

介绍热轧卷取机控制系统由恒张力控制改造为变张力控制的过程及实际应用情况,就热轧卷取机变张力控制的原理、卷径记忆与测量及动态张力补偿等进行了分析。

The article describes the course and practical application of the control system in coiler of hot rolling mill,which is transformed from the constant tension control into variable tension control,as well as analyzes the coiler of hot rolling mill from the aspects of the variable tension control principle,winding diameter memory and measurement and dynamic tension compensation.
