冷轧板材和带材是国家急需之产品,在努力实现四个现代化中尤为重要。而冷轧工作辊则是冷轧薄板生产中的大型工具,十分关键。所以,冷轧工作辊的来源与质量,将直接影响冷轧薄板生产的产量、质量及生产成本。鞍钢冷轧厂开工至今,冷轧工作辊的来源大部分是靠进口,曾先后用过苏联、英国、日本等国的辊。有部分工作辊是靠国内供应,曾使用过富重、沈重、太重、 Cold-rolled sheet and strip are the products urgently needed by the country and are especially important in striving to achieve the four modernizations. The cold-rolled work roll is a large tool in the production of cold-rolled sheet, is very crucial. Therefore, the source and quality of the cold-rolled work rolls will directly affect the production, quality and production costs of cold-rolled sheet production. Since the start of Anshan Iron and Steel Cold Rolling Plant so far, most of the source of cold-rolled work rolls rely on imports, has used the Soviet Union, Britain, Japan and other countries roll. Some of the work rolls are supplied by domestic sources. They used heavily, heavy, too heavy,
