几年来,我国轧钢生产技术有了迅速的发展,钢材的产量、质量和品种方面都有了大幅度的增长和提高,基本上满足了国民经济各部门的迫切需要。但是,也应当看到我国的钢材品种,与工、农业生产建设各部门的实际需要比较起来,还是有一定的距离。为了指出我国今后扩大钢材品种的方向,本文参考了世界各主要钢、铁生产国家自第一次世界大战前夕迄今的钢材品种演变情况,以及部分国家的钢材用途情况,并结合我国的实际情况,加以论述。最近几年来,可以清楚地看到,,虽然各国轧钢生产的情况各有不同,但有一个共同的特点,那就是各国的板钢产量在钢材总量中所占的比例,一直在逐年的上升,尤其薄板的产量,正在迅速地增长着。美国1961年板钢产量占钢材总量的66.7%,而薄板产量即
In recent years, China’s steel rolling production technology has developed rapidly, steel production, quality and variety have a substantial increase and increase, basically to meet the urgent needs of all sectors of the national economy. However, we should also see that the varieties of steel in our country still have a certain distance from the actual needs of various departments in the fields of industry and agricultural production and construction. In order to point out the direction of our country to expand the varieties of steel products in the future, this article has made reference to the evolution of steel products in the world since the eve of the First World War and the use of steel products in some countries. Based on the actual situation in our country, To be discussed. In recent years, it can be clearly seen that although the situation of rolled steel production varies from country to country, there is a common characteristic that the proportion of plate steel production among the total steel products in various countries has been increasing year by year In particular, sheet production is rapidly growing. US steel production in 1961 accounted for 66.7% of the total steel, and sheet production that
