太钢炉卷轧机液压压下改造从1974年底开始,经过调研、设计、模拟试验、在小型轧机上试验、加工制造、试验室动态试验和现场安装、调试等阶段。现场安装、调试由太钢负责组织,钢铁研究总院、冶金部自动化研究所、丹东电子研究所等单位参加组成联合试验小组,从1979年9月中旬开始工作,于10月12日用APC控制炉卷轧机轧钢,一次试验成功。从1980年开始,除二月份因油缸检修和更换密封圈没有使用外已生产试运转三个多月,并取得
Taichung furnace roll hydraulic pressure transformation from the beginning of the end of 1974, after research, design, simulation test, small mill test, manufacturing, laboratory dynamic test and site installation, commissioning and other stages. On-site installation and commissioning was organized by TISCO. The Steel Research Institute, the Institute of Metallurgy Automation, Dandong Institute of Electronics and other units participated in the formation of a joint experimental group. Starting from mid-September 1979, they were controlled by APC on October 12 Steel rolling mill, a successful test. From 1980 onwards, in addition to the oil tank overhaul and replacement of the seal did not use outside the production test run more than three months, and made
