电弧炉炼钢是黑色冶金中发展较快的一种炼钢方法。目前,世界钢产量每年在7亿吨上下波动,基本上处于缓慢增长状态,而电炉钢产量却稳定上升。1980年,全世界钢产量电炉钢产量占23.1％,平炉钢产量占24.3％,转炉钢 Electric arc furnace steelmaking is a rapidly developing method of steel making in black metallurgy. At present, the world’s steel output fluctuates 700 million tons a year, basically in a slow growth state, while the output of electric furnace steel has steadily risen. In 1980, the world’s steel production accounted for 23.1% EAF steel, open hearth steel production accounted for 24.3%, converter steel
