冷连轧生产过程同步数据的建立与应用

Building and Application of Synchronized Data in Tandem Cold Rolling Process

针对冷连轧生产过程中现有的数据采集与分析系统的不足,结合某1450 mm五机架冷连轧机组仪表配置,提出了一种冷连轧机带钢段同步数据的建立方法.该方法主要包括快照数据建立和同步数据构建两个过程,可以将带钢轧制过程中实时采集的实测轧制参数映射到成品钢卷的长度上,通过同步数据可以查看每卷带钢在任意长度上的轧制数据.本文所提出的带钢段同步数据的建立方法已投入到某1450 mm冷连轧机组生产中,自投入运行后控制系统运行稳定,为快速诊断生产故障、分析成品钢卷质量提供了有力的手段.

In view of the shortcomings of existing data collection and analysis system in the production process of tandem cold mill, a synchronization method of strip segment data for tandem cold mill was proposed based on the mill equipment and instrument configuration of a 1450 mm five-stand tandem cold mill, which consists of two parts： photo data building and synchronized data building. With this method,the various measurement parameters of rolling process can be synchronized to the rolled length at the last stand, and the rolling parameters o f any coil length can be monitored through synchronized segment data. The method of synchronizing the strip segment data has been applied successfully in a five-stand tandem cold mill, and the control system runs steadily after putting into operation. The method of synchronizing segment data offers a convenient way for the technicians,who can diagnose production fault and analyze products quality rapidly.
