1.60年代,我国自力更生建设了几套大轧机,如舞阳4200mm厚板轧机,本溪1700mm热带轧机,太钢2300mm单张冷轧机等。当时受外来因素影响,采用全部国内制造的错误作法,降低了水平,耽误了生产。但是,只要布局好,以后通过改造提高水平还是可能的。 2.70年代以来,有目的的引进了国外设备,收效很好,如太钢冷轧不锈带钢轧机,武钢1700mm轧机,宝钢二期工程2套轧
1.60 years, our country self-reliant construction of several sets of large rolling mill, such as Wuyang 4200mm plate mill, Benxi 1700mm tropical mill, TISCO 2300mm sheet cold rolling mill and so on. Influenced by external factors at that time, all the mistakes made in China were used to reduce the level and delay the production. However, as long as the layout is good, it is still possible to raise the level through renovation. 2.70 years since the purpose of the introduction of foreign equipment, with good results, such as Taigang cold-rolled stainless steel strip mill, 1700mm mill Wuhan Iron and Steel, Baosteel 2 sets of two rolling project
