汽车板钢生产及其主要发展方向增加板材在钢材总量当中的比例数,是现代技术发展的规律之一。这是由焊管生产、汽车业、电工业及其他工业部门发展所决定的。各大产钢国都在扩大其板钢生产规模,情况甚引人注目。80年代以来,轧板生产不断发展 Automobile slab production and its main development direction Increasing the proportion of plate in the total amount of steel, is one of the laws of the development of modern technology. This is determined by the development of welded pipes, the automotive industry, the electric industry and other industrial sectors. The major steel producing countries are expanding their production of sheet metal, the situation is very noticeable. Since the 1980s, rolling production continues to grow
