钢材是钢铁工业与用户见面的最终产品。三十多年来,我国已形成了一定规模的轧钢生产体系,品种、数量逐年增长,质量逐年提高,基本上与国民经济各部门的发展相适应。我国现有轧机约一千套,虽然也有像武钢一米七那样的七十年代的装备,但年产三千万吨左右的钢材主要还是靠五十年代甚至更古老的轧机生产出来的。技术装备落后,工艺陈旧,产品结构不合 Steel is the final product that the steel industry meets with customers. In the past three decades, a certain scale of rolling production system has been formed in our country. The varieties and numbers of them have been increasing year by year, and the quality has been increasing year by year, which is basically in line with the development of various departments of the national economy. There are about a thousand sets of existing rolling mills in our country. Although there are also some 70-year-old equipment like the one in Wuhan, the annual output of 30 million tons of steel is mainly produced by even the older mills in the 1950s. Outdated technology and equipment, technology obsolete, product mix
