新的液压ＡＧＣ技术成功地应用在１２００ＷＳ四辊可逆冷轧机上，取得了较好的控制效果，０．５～１．５ｍｍ带材的最终厚度公差小于带材厚度的±１％。本文介绍了该液压ＡＧＣ系统的组成及功能，论述了几种ＡＧＣ的控制模型和特点以及新技术在ＡＧＣ中的应用，对ＡＧＣ应用中的有关问题进行了讨论。
The new hydraulic AGC technology has been successfully applied to the 1200WS four-roller reversing cold rolling mill and has achieved good control effect. The final thickness tolerance of 0.5-1.5mm strip is less than ± 1% of the strip thickness. This paper introduces the composition and function of the hydraulic AGC system, discusses several control models and characteristics of AGC and the application of new technology in AGC, and discusses the related problems in the application of AGC.
