1 前言 有后燃烧和无后燃烧的试验结果证明电弧炉内后燃烧的潜力。它们还证明在工业实践中,通过优化氧枪设计和操作方法可以获得的效率。 从六十年代初期开始,熔池下吹氧已经是电炉炼钢中的一个标准作业。20多年来,用于吹氧的常用耗氧量已从2Nm~3/吨增加到17.5Nm~3/ 1 Foreword The post-combustion and post-combustion test results demonstrate the potential for post-combustion in an EAF. They also demonstrate the efficiency that can be achieved in industrial practice by optimizing the oxygen lance design and method of operation. Since the early 1960s, oxygen blowing under the bath has been a standard practice in EAF. For more than two decades, the usual oxygen consumption for oxygen blowing has increased from 2 Nm 3 / t to 17.5 Nm 3 /
