连轧作业区的微张力控制轧制的应用实践

Application of Micro Tension Controlled Rolling Process in Continuous Rolling Operation Area

分析连轧作业区棒材生产线的微张力自动控制过程,并通过对机架出口轧件的型铁面积,轧制表上的主设定等参数的修改,采用中轧区张力封锁等措施,使控制过程得以稳定,成品尺寸精度得到提高。

This paper analyzed the micro tension automatic controlling process for the bar production line in the continuous rolling operation zone. The control process was kept to be stable and the size precision of finished product was improved by changing some parameters such as the area of profiled iron for outlet rolled pieces in the rack, the main settings in the roiled table, taking measures of locking tension in the middle rolled region and so on.
