Technology upgrading and application of regional automatic control system for bar rolling line
In order to improve the concentration of production factors and maximize the benefit of the bar production resources, Xuanhua Iron and Steel Company upgraded the production process of the deformed steel bar of No.3 bar rolling line in July 2020, which has been upgraded from single line rolling to single line slitting rolling. After the upgrading of the production process, the annual output of the No.3 bar roll⁃ing line is more than 1.2 million tons. With the improvement of the process and production indicators of this rolling line, the electrical and automation equipment of this rolling line must be expanded and im⁃proved to meet the current production requirements and efficiency. This paper introduces the production status of the No. 3 bar rolling line in Xuanhua Iron and Steel Co., Ltd., analyzes the problems existing in the current electrical and automatic control system, and puts forward a plan for upgrading the electrical and automatic systems in the main bar rolling line area. After the upgrading and transformation of the con⁃trol system, the production requirements of the No.3 bar rolling line after the transformation were met.
