高速线材轧线夹送辊工作过程分析及其参数设置

WORK PROCESS ANALYSIS AND PARAMETER SETTINGS OF HIGH SPEED WIRE PINCH ROLL

介绍了国内某进口高速线材生产线吐丝机前夹送辊的生产工艺过程。阐述了夹送辊的重要作用及控制逻辑,就参数设置对线材生产的影响进行了逐项讨论。分析表明:为保证夹送辊的功能正常,控制分为张力模式和速度调节模式两个阶段。操作人员对超前速度、夹紧压力、张力控制等参数的设置决定夹送辊的功能能否正常发挥,并对轧线生产连续性有直接影响。

This paper introduced the working process of pinch roll of an improted high-speed wire production line before spinning machine in China.The importance and control logic were clearly stated,while the settings on the production of wire rod were discussed item by item.It was concluded that the control process could be categorized as tension control mode and speed regulation mode,and that the setup of lead speed,clamping pressure and tension control parameters could significantly influence the continuous production of the whole mill.
