一、工艺过程武钢是我国深冲冷轧薄钢板的主要生产厂家,近年来汽车制造行业同时采用武钢、鞍钢和日本的深冲冷轧薄板制造汽车的覆盖件。武钢和鞍钢的产品同属国家优质产品。武钢深冲冷轧薄板的生产始于1978年10月,开工初期以西德St14钢用于冷轧生产,按DIN1623考核。1979年武钢根据YB215—64开始了08Al超深冲薄钢板的试生产,到1980年原料全部自己生产,并根据自产料的具体情况制订了生产工艺。历年的生产情况如表1和图1所示。
First, the process Wuhan Iron and Steel is China’s deep-drawn cold-rolled steel sheet of the major manufacturers in recent years, the automobile manufacturing industry at the same time using WISCO, Anshan Iron and Steel and Japan’s deep-drawn cold-rolled sheet to cover the car. WISCO and Anshan Iron and Steel products belong to the same high-quality products. WISCO deep-drawn cold-rolled sheet production began in October 1978, the early start to West Germany St14 steel for cold-rolled production, according to DIN1623 assessment. In 1979, WISCO started the trial production of 08Al ultra-deep-drawn steel plate according to YB215-64. By 1980, all the raw materials were produced by themselves and the production process was formulated according to the specific conditions of the self-produced materials. The past years of production as shown in Table 1 and Figure 1 below.
