Research in Hot-Rolling Downcoiler Dynamic Torque Control

Abstract:

Torque control of hot strip coiler affects the telescopicity of steel coil. The hot yield point of steel is different in different temperature, it affects the bending torque of steel strip, the strip coiling temperature is about 500-700,and what obtained through the study of steel hot yield point is that large change of hot yield point happens in every 50 degrees of temperature change. In order to track the load torque accurately, compensation of torque for temperature change is necessary. It can make torque tracking accurately, and improve the telescopicity of steel coil.
