Study and Application of SSC Model on Hot Rolling Wide Strip Mill

Abstract

According to cutting loss of the head and the tail of hot rolling wide strip mill for the loss of width, the control conditions, the control mode and control model of short stroke control (SSC) of the rough mill are researched and given by dynamical changing the rough mill roll gap for SSC simulation and basing on infinite element method (FEM) analysis and results. When the SSC model is put into use in the field, the width difference of the head and the tail with the body of the strip are decreased. Therefore, the SSC model greatly improves the control accuracy of strip head and tail, and achieves the desired results.
