目前,全世界生产的钢有40％是用废钢炼成的,西德可在大约十年内增加到55％。因此废钢在将来还要有更为重要的商业地位,西德马克斯修特钢厂已研究发展出一种方法,使底吹氧转炉有可能大量增加废钢用率。这种方法包括利用转炉底部的吹氧风管作为予热废钢用的燃烧喷头,以及装在转炉上部的侧风管作为转炉发生气后燃烧用的喷头。在平均予热时间2.5
At present, 40% of the world’s steel is made from scrap and West Germany can increase to 55% within about a decade. As a result, scrap is expected to have a more significant commercial presence in the future, and Sdeter Maxter Steel has developed a methodology that will make it possible to significantly increase scrap utilization at the bottom blowing oxygen converter. This method involves the use of an oxygen blowing duct at the bottom of the converter as a burner for preheating scrap and a side duct mounted on the upper portion of the converter as a burner for the afterburning of the converter. The average preheating time 2.5
