宝钢第三热轧线液压活套控制方式实现

The Realization of the Third Looper Hot Line Hydraulic Control in Baosteel

宝钢第三热轧线活套采用新型伺服液压系统,比其它两条热轧线活套马达控制方式响应更快、精度更高。三热轧活套控制系统除了传统控制方式之外,还有较为先进的张力与角度结耦控制的ILQ控制方式,前机架间还可以选择投入微张力控制。针对三热轧活套的特点,对活套的控制方式和时序进行研究分析,提高活套在生产过程中的稳定性。

Loopers in No.3 hot rolling mill adopt the servo hydraulic system, which have quick response and high accuracy than the motor control loopers in NO.1 and NO.2 hot rolling mill. Besides the convention control mode, there is also ILQ control mode in NO. 3 hot rolling mill, which uses the coupling control in tension and angle. It also can choose to use Iooperless control in the frontal stand. It analyses the control mode and timing through the loopers characteristic in NO.3 hot rolling mill in order to advance the looper stability in production.
