直拉式冷轧实验机自动控制系统

为了满足钢铁企业加强冷轧生产技术研究能力的需要,轧制技术及连轧自动化国家重点实验室(RAL)自主设计开发了垂直方向采用液压自动厚度控制(HAGC),水平方向两侧通过液压缸和夹头产生张力进行自动张力控制(ATC)的新型直拉式可逆冷轧实验轧机.概要地介绍了直拉式冷轧实验机的设备构成及设备的主要功能和特点,详细说明了控制系统构成及自动控制功能的实现,通过系统测试给出了系统控制精度.测试结果表明冷轧实验工艺过程可以模拟生产工艺过程,进行冷轧钢种开发和工艺研究.

Automatic Control System of Direct Tension-type Pilot Cold Rolling Mill

To meet iron and steel enterprises requires to strengthen research capacity in cold-rolled production technology,State Key Laboratory of Rolling and Automation(RAL) independently designed and developed a new direct tension-type pilot cold rolling mill,which includes a vertical hydraulic automatic gauge control(HAGC) generating tension through the hydraulic cylinders and chucks on both sides of the horizontal direction to realize automatic tension control(ATC).The equipment constitute,main functions and features of direct tension-type pilot cold rolling mill were introduced briefly.The control system structure and the realization of automatic control functions were illustrated.The control precisions were gotten through system testing.The testing results showed that the experimental process may simulate the cold rolling production process to develop steel grade and research technology.
