摘要�介绍了承钢中宽带钢生产线精轧机组自动化系统改造的应用实例。在改造中对影响产品质量较
大的活套控制与压下控制做了功能性改进,特别是压下系统,在硬件设备较为落后的情况下,利用软件
精确的数学模型进行位置闭环控制,弥补了硬件的不足,满足了生产工艺对活套系统的稳定控制与压下
系统的精度要求。

Abstract It is introduced the reformation of automation system of finishing mill set in medium - width strip
,
steel line of Cheng Steel. The loop control and screw - down control systems which have an important effect
, ,
on the products quality are improved in function. Especially for the latter under condition of relatively
,
backward hardware a software mathematical model is used in location closed - loop control to perfect the
hardware system. The improvement ensures the demands of production for steady of loop and the precision of
screw - down system.
