日本住友金属王业公司的第一台冷轧机——和歌山钢铁厂的冷轧带钢轧机于1963年开始运转。自1971年鹿岛厂的新轧机开工以来,和歌山钢铁厂轧制薄带的比例正在增加。而且,市场对冷轧带材和镀锌钢板的质量要求愈来愈高,特别是对厚度公差的要求,更为严格。这些趋向促进了和歌山钢铁厂轧机实现现代化的进程。这个现代化规划涉及到对目前存在的问题进行调查研究。为同新近建设的现代 Japan’s Sumitomo Metal Wangye’s first cold-rolling mill - Wakayama Steel Plant’s cold-rolled strip mill started operation in 1963. Since the start-up of the new mill at Kashima plant in 1971, the ratio of rolling strip at Wakayama Plant has been increasing. Moreover, the market demand for cold-rolled strip and galvanized steel higher and higher, especially for the thickness tolerance requirements, more stringent. These trends have promoted the modernization of the rolling mill at Wakayama Steel Plant. This modern planning involves the investigation of existing problems. For the same with the recent construction of the modern
