日本川崎钢铁公司水岛厂生产方钢和圆钢的钢坯车间,为提高生产率和降低成本,采用无孔型轧辊(平辊)进行轧制方法,取得成效。钢铁联合企业采用连铸设备对降低生产成本效果极大,故实现以连铸为中心的生产工序合理化,正成为降低成本的主流。而在生产流程上,将这种新轧制法与连铸相结合具有很大意义。水岛厂钢坯车间第一阶段仅在可逆式粗轧机组(第一机列5个机架,第二机列2个机架)上采用平辊进行轧制,后来扩大到连 Japan’s Kawasaki Steel Mizushima plant production of square steel and round billet workshop, in order to improve productivity and reduce costs, the use of non-perforated roll (flat roll) rolling method, and achieved results. The use of continuous casting equipment in the iron and steel complex is extremely effective in reducing production costs. Therefore, rationalizing the production process centered on continuous casting is becoming the mainstream of cost reduction. In the production process, the combination of this new rolling method and continuous casting is of great significance. The first phase of Shuidao Plant’s billet workshop was carried out by means of a flat roll rolling only on a reversible roughing train (5 racks in the first train and 2 racks in the second train)
