武钢一米七轧机专用刀片国产化。最近,97种规格的刀片全部由常州冶金机械厂研制成功,替代进口刀片,每年为国家节省外汇上百万美元。武钢一米七轧机主联动线上的主要专用刀片材质特殊,形状复杂,技术精度要求高。轧机投产后,备用刀片消耗量大,需耗费国家大量外汇。冶金部决定立足国内自制。从1979年起,常州冶金机械厂采用大冶钢厂特殊冶炼的新材料以及该厂先进的金属加工工艺和热处理方法,逐年加强检测工作,使刀片质量稳定提高。
WISCO seven meters rolling mill for domestic localization. Recently, 97 kinds of blades are all successfully developed by Changzhou Metallurgical Machinery Factory to replace imported blades, which save the country millions of dollars of foreign exchange each year. Wuhan Iron and the first seven m rolling mill main line on the main special blade material special, complex shape, high technical precision requirements. After the mill is put into production, the spare blade consumes a large amount of power, which consumes a large amount of foreign exchange in the country. The Ministry of Metallurgy decided to base itself on domestic self-control. Since 1979, Changzhou Metallurgical Machinery Plant adopted a special smelting of new materials and Daye Metallurgical plant advanced metal processing technology and heat treatment methods, year by year to strengthen testing, the blade quality and stability improved.
