在冷轧厂,对经过罩式炉退火以后的冷轧带钢,还必须进行一次平整性质的轧制工艺处理。这样,冷轧带钢的深冲性能才能满足冲压工艺的需要。武汉1700冷轧带钢厂,按照生产具有深冲性能的冷轧带钢的设计,安装了单机架平整工艺作业线,和带有二次冷轧性能的双机架平整工艺作业线。 在正常的生产过程中,为了使单机架机组和双机架机组能够完成设计中规定的产量指标和质量指标。西德BBC公司采取的手段之一是设计了一个采用Procontic-M型超小型机为中央处理单元的延伸率控制系统。
In cold-rolling plants, cold-rolled strip after annealing in a bell-type furnace must also undergo a smooth rolling process. In this way, deep drawing of cold-rolled steel to meet the needs of stamping process. Wuhan 1700 cold-rolled steel strip mill, according to the production of deep-drawn strip cold-rolled steel design, installation of a single-frame leveling process line, and with two cold-rolled double-flat flattening process line. In the normal production process, in order to make the single-frame unit and double-frame unit to complete the design of the production specifications and quality indicators. One of the approaches taken by West Germany BBC was to design an elongation control system using the Procontic-M as a central processing unit.
