日本住友金属工业公司鹿岛厂投资400亿日元,新建了2号冷带轧机。该轧机生产厚0.35～2.4 mm、宽600～1880 mm、卷重最大为46.5 t的冷轧宽带钢,出口速度最高为1300 m/min,月产能力10万吨。为了适应汽车轻量化的要求,此轧机以生产超高强度材和高成形性产品为主。为此,该五机架全连续式冷连轧机的前三架首次采用轧辊成对交叉式四辊轧机(三菱重工业公司制造),可进行高压下轧制和获得高的板厚精度;后两架轧机采用六辊式
Japan’s Sumitomo Metal Industries Kashima plant invested 40 billion yen, the new No. 2 cold strip mill. The mill produces cold-rolled wide strip with thicknesses of 0.35 to 2.4 mm, widths of 600 to 1880 mm and a maximum roll weight of 46.5 t with a maximum exit speed of 1300 m / min and a monthly capacity of 100,000 t. In order to meet the automotive lightweight requirements, this mill to produce high strength materials and high formability products. For this reason, the first three of the five-stand full tandem cold mill are for the first time used a pair of crossed four-roll mill (manufactured by Mitsubishi Heavy Industries, Ltd.) for high-pressure rolling and high sheet thickness accuracy; the latter two Rolling mill with six-roll
