由北京科技大学和唐山钢铁公司共同研究的微机控制钢筋轧后控冷工艺,已应用于唐钢一小型厂。用该工艺生产的20Mnsi及A3(K3)钢筋的性能达到了新Ⅲ级和英国BS4449—88标准要求。 1.微机控制轧后冷却工艺的设计 1.1 微机控制轧后控冷工艺系统微机控制轧后控冷工艺系统由余热处理系统、仪表调节系统和微机控制系统组成,安装在φ250小型轧钢厂成品轧机之后。其
By Beijing University of Science and Technology Co., Ltd. and Tangshan Iron and Steel Company jointly controlled by computer-controlled steel bar after cooling control technology has been applied to a small Tangshan Iron and Steel Plant. The performance of 20Mnsi and A3 (K3) rebar produced with this process has reached the new grade III and British BS4449-88 standards. 1. Microcomputer control design after rolling cooling process 1.1 Microcomputer controlled rolling after cooling control system Microcomputer controlled rolling after cooling control system consists of waste heat treatment system, instrumentation and computer control system components, installed in φ250 small mill after the mill . its
