一、前言电弧炉传统冶炼工艺的特点是钢液要在白渣下长时间保持进行扩散脱氧。优点是能够对钢液进行充分脱氧、脱硫,故钢中夹杂含量一般较低。但是该工艺的缺点是钢液易吸气。炼钢还原期由于碳氧反应基本停止,钢中气体含量会不断增加,特别是过分延长还原期,该缺点就更为突出,而且电能、造渣材料消耗多,炉衬侵蚀加剧。因此缩短、甚至完全取消还原期是当前炼钢节能的一项重要技术措施。电弧炉单渣冶炼技术早在四十年代已由英、美等国提出并作为一种常规的冶炼工艺应用于生产,到1976年美国单渣钢的产量约占电弧炉钢总产量的三分之二。国内早在五十年代就开展过单渣钢的试验
First, the foreword The traditional EAF smelting process is characterized by liquid steel to stay in the white residue for a long time to spread oxygen. Advantages of being able to full deoxidation of molten steel, desulfurization, it is generally lower inclusion content in steel. However, the disadvantage of this process is that the liquid steel is easily sucked. The reduction of the steelmaking period due to the basic stop of the carbon and oxygen reaction, the gas content of steel will continue to increase, especially the excessive extension of the reduction period, the shortcomings are more prominent, and electricity, slagging material consumption, furnace lining erosion intensified. Therefore, reducing or even completely canceling the restoration phase is an important technical measure for energy saving in steel making. Arc slag single slag smelting technology as early as the forties has been proposed by the United Kingdom, the United States and other countries as a conventional smelting process used in the production of the United States by 1976 single slag production accounts for about one-third of EAF steel production of two. As early as the fifties of the country had carried out a single slag test
