摘要
回顾了我国电炉炼钢发展情况,指出:由于目前我国废钢及电力紧缺,电炉钢成本较高,电炉炼钢存在一定困难,中国电炉钢的比例正面临着1990年以来第二次逐年下降的局面。使我国电炉钢生产走出困境的措施主要有3条,一是生产高附加值钢;二是通过电炉加部分铁水冶炼和强化用氧,缩短冶炼周期,降低成本;三是引导企业发展现代电炉,进行第二轮投资。
Development of EAF steelmaking in China is reviewed. Because the scrap and the electric power are in short supply, the difficulty of EAF steelmaking is that the EAF steel cost is higher than that of converter steel. And this has resulted that the rate of EAF steel is decreasing year after year, as second case since 1990 in China. There are three measures to deal with this difficulty, the first one is producing high added value steel, the second one is shortening the tap to tap time for decreasing cost by adding a part of hot metal and increasing oxygen blowing rate in EAF steclmaking; and the third one is guiding the steelmaking plants to carry out the second round investment to develop the modern electric arc furnace.
