摘要
在不锈钢带滚切加工工艺中,原料带钢要经过放卷、滚切、分条卷取3道工序完成。其中放卷与卷取过程是整条生产线的2个重要环节,按滚切工艺要求要确保不锈钢带在恒线速度恒张力条件下进行放料和卷取。采用高性能矢量控制变频器分别驱动放卷、滚切和卷取轴的执行电机,以滚切机传动为基准速,并建立了速度反馈和张力前馈校正相结合的数学模型,实现对不锈钢带恒张力卷取。
In the process of roll-cutting processing for the stainless steel strip, raw material should undergo unwinding, roll-cutting and winding by strips total three steps to complete. Of the above three steps, unwinding and winding are two important links in the entire production line. According to requirement of roll-cutting processing, unwinding and winding under the circumstances of constant tension at a constant speed of stainless steel strip should be assured. Based on transmission speed of roll-cutting shearer, high-powered vector control converter was applied to drive implementation motor for unwinding, rolling-cut and winding axis respectively. And it established a mathematical model combing speed feedback and tension feedforward correction to achieve winding of the stainless steel strip under constant tension.
