为了降低能耗,用炼钢电弧炉冶炼当地废钢,在国外非常盛行,它不仅在发展中国家,即使在发达国家也同样如此,废钢——电炉——连铸——轧机设备先进模式的中小钢厂的出现令人瞩目。据有关资料介绍,1984年世界电弧炉炼钢的钢产量已达1.6亿吨,预计,至1900年世界电弧炉炼钢的钢产量将以4.4％的年增长率上升,小钢厂的发展正方兴未衰。在我国,电炉炼钢也取得较大的发展。1982年和1983年全国电弧炉炼钢,分别占全
In order to reduce energy consumption, the use of steelmaking electric arc furnace smelting local scrap, very popular in foreign countries, it is not only in developing countries, even in developed countries as well, scrap - electric furnace - continuous casting and rolling mill equipment advanced model of small The emergence of steelworks is remarkable. According to relevant information, in 1984, the world’s EAF steel production reached 160 million tons. It is estimated that the world’s EAF steel production will increase at an annual rate of 4.4% by 1900 and the development of small steel mills Hing is not bad. In our country, EAF also made great progress. In 1982 and 1983, the national electric arc furnace steelmaking, respectively, accounted for
