摘    要：武汉钢铁集团公司三热轧1580 mm热连轧机精轧机活套控制系统采用先进的数学模型,精确计算活套动作的各项控制参数,实现机架间带钢的恒定套量控制和微张力控制。数学模型包括活套套量数学模型和活套张力数学模型。实际应用结果表明,采用该数学模型的活套套量控制器和张力控制器都获得了较好的控制效果,降低了精轧机堆钢和拉钢事故的发生,提高了产品产量和成材率。

Abstract: In looper control system for finishing rolling mill of 1 580 mm hot strip mill in the 3rd Hot Rolling Plant of WISCO,advanced mathematic model is adopted to calculate parameters of looper and realize constant looper height control and micro-tension control of strip between stands.The mathematic model includes looper height model and looper tension model.The model has been applied to looper height controller and tension controller.Practical application results show that good control effect was obtained,strip piling and pulling during rolling were reduced,and production output and economic benefits were improved.
