粗钢的发展 西德粗钢生产情况表明,现在有明显地仅用氧气炼钢和电炉炼钢的发展趋势(图1)。日本也是这样。氧气炉钢占总产量的81％,电炉钢占15％,这标志着西德钢铁工业当今的形势。就世界情况看,1980年钢产量的50％是氧气炉钢,其余是平炉钢和电炉钢,各占比例大致是一半。根据以下几点原则来选择合适的炼钢方法; ——地点; ——可供使用的原材料、废钢和能源的
The development of crude steel The production of crude steel in West Germany shows that there is now a clear trend toward oxygen-only steelmaking and EAF steelmaking (Figure 1). The same is true in Japan. Oxygen furnace steel accounted for 81% of the total output, electric furnace steel accounted for 15%, marking the current situation in the West Germany steel industry. As far as the world situation is concerned, 50% of the steel output in 1980 was oxygen furnace steel and the rest were open hearth furnaces and electric furnace steels, each accounting for about half of the total. Select the appropriate steelmaking method based on the following principles; - location; - availability of raw materials, scrap and energy
