2015年8月24日,武钢冷轧总厂二冷轧酸轧机组突破自身设计生产能力,首次成功轧制出321.5t超高强钢,其质量合格率达到98.3%。8月份,冷轧总厂接到柳州五菱汽车厂家的订单,本着快速响应市场的作法,二冷轧迅速承接生产任务。这批超高强钢产品的抗拉强度达到780MPa,产品的宽度达到1 675mm,超出二冷轧酸轧机组的设计规格。 On August 24, 2015, the second cold rolling mill of WISCO Cold Rolling Plant broke through its own designed production capacity. For the first time, it successfully rolled out 321.5t ultra-high strength steel with a passing rate of 98.3%. In August, the Cold Rolling Plant received an order from Liuzhou Wuling Automobile Co., Ltd. In line with the rapid response to the market practice, the second cold rolling mill quickly took over the production task. The tensile strength of these ultra-high strength steel products reached 780MPa, the width of the product reached 1675mm, exceeding the design specifications of the second cold rolling mill.
