摘要
造成武钢热轧厂带钢宽度精度偏差的主要原因是粗轧机组的头尾失宽现象，而头尾失宽的主要原因是板坯在立辊中的变形特点、头尾与中间部分的温度差及初轧坯料的缺陷所致。改善工艺和设备可以减少失宽现象。根本措施是采用调宽压力机。
The main reasons causing strip steel width exceed standard are that the width of piece rolling in rough mill can not be controlled.This is decided by characteristics of slab deformation,temperature different in head and tail,defect of slab. The condition of width lose controlling can be decreased by impproving technology and equipment.In order to solve this problem thoroughly, the width adjust pressure machine must be used.
