武钢从西德引进的一米七带钢冷连轧机,每秒轧制速度可达30米,是国内仅有的现代化宽五机架冷轧机组。在该机组上工作的φ610×1700毫米冷轧工作辊是重要的消耗部件,苛刻的轧制条件,要求轧辊具有高的硬度,良好的耐磨性和抗事故能力。武钢冷轧厂1978年投产至1980年11月完全使用主要从西德进口的冷轧工作辊,每年要耗费大量外汇。轧辊自给问题亟待解决。 1978年至1980年原第一机械工业部和冶金部曾联合进行过初次研究试制,由于经验不足等原因,未能研制成一对供上机考核的试验辊。 1980年冶金部组织试制攻关,攻关组成员有齐钢、邢冶、衡冶、北京钢铁学院、钢
WISCO introduced a one-meter-seven strip tandem cold rolling mill from West Germany at a rolling speed of up to 30 meters per second, making it the only modern cold rolling mill with a wide range of five stands in the country. The φ610 × 1700 mm cold rolling work roll working on this unit is an important consumable part. Harsh rolling conditions require the roll to have high hardness, good wear resistance and resistance to accidents. WISCO cold-rolled steel plant was put into operation in 1978 to November 1980 Full use of cold-rolled work rolls imported mainly from West Germany consumes a large amount of foreign exchange each year. Roll self-sufficiency problem to be solved. From 1978 to 1980, the former Ministry of Machinery Industry and the Ministry of Metallurgy jointly conducted the first trial trial. Due to lack of experience, it failed to develop a pair of test rollers for on-board evaluation. In 1980, the Ministry of Metallurgy organized a pilot program to tackle trial production.
