900 mm热轧生产线精轧活套控制系统优化
Optimization of the Finishing Mill Looper Control System on 900 mm Hot Rolling Production Line

文章对900 mm热轧生产线精轧活套控制系统的功能及其对带钢质量的影响进行了分析。为提高活套控制系统对不锈钢窄带生产的适应性，从轧机主速度补偿、起套响应速度、稳套工作张力、落套等待时间四个方面进行了优化。生产实践表明，优化后的控制系统稳定性明显提高，轧制精度得到了改善。
The function of the finishing mill looper control system on the 900 mm hot rolling production line and its impact on strip steel quality were analyzed in this paper. In order to improve the adaptability of the looper control system to the production of stainless steel narrow strips, optimization was carried out from four aspects: main speed compensation of the rolling mill, response speed of the looper, working tension of the stable looper, and waiting time for the looper to fall. Production practice shows that the stability of the optimized control system is significantly improved, and the rolling accuracy has been improved.
