活套控制技术在莱钢热轧带钢生产线上的应用

Application of Loop Control Technology in Hot Rolled Strip Production Line in Laigang

介绍了莱钢1500m m热轧带钢生产线精轧机组活套系统中采用的活套位置检测自动校零技术、活套升套过程软接触技术以及自适应活套落套控制技术。通过这几种技术的应用,解决了各种干扰所导致的带钢流量和张力的扰动,保证了轧制顺利和带钢质量的改善,成材率由原来的94%提高到98%。

Introduces the loop location detection automatic check zero technique, the soft contract technique of loop-rising process and the self-adapting loop-dropping control technique used in the finishing train looper system of the 1500mm hot rolled strip production line in Laigang. Though the application of these techniques, the turbulences of the strip flux and the tension resulted in all kinds of interferences are debarred, ensuring the rolling all right and improvement of the strip quality. Therefore, the rolling yield is increased to 98% from 94%.
