摘　　要：由于开卷机运行过程中,对于剩余带钢长度计算不正确,自动控制效果已不能满足生产要求;由于设备条件所限,对宽厚带材的矫直能力不够;开卷机带钢自动甩尾功能效率降低等原因造成宝钢分公司2030冷轧酸洗机组开卷机自动刹车失控。通过对开卷机圆周自动补偿计算,选用卷径平均值处理模块,增设带钢来料长度递减模块和刹车双重控制功能,优化开卷机自动刹车控制模块,提高了开卷机剩余带钢长度的计算精度,避免了入口带钢高速甩尾现象的发生以及由此产生的设备故障停机。In the process of the payoff reel＇ s operation, the steel strip＇ s leftover length can not be calculated correctly, which has made the automatic control effect fail to meet the requirement of the production. The payoff reel＇ s automatic brake for 2030mm cold mill pickling line failed to function due to the limited equipment condition, poor flattening ability for wide and heavy strips and unqualified automatic tail out action of the payoff reel. With the follow- ing measures like calculating the reel＇s circumference in an automatic compensative way, choosing a module to deal with the average value of the coil diameter, adding a module that makes the strip＇ s length decrease gradually, and a brake with double control function, and optimizing the automatic control module of the payoff reel brake system, the counting precision for the length of leftover steel strip has been improved. It can avoid the tail out happening once more and reduce the downtime for the equipment failure.
