1986年8月21日至23日,冶金部组织了北京钢铁学院、钢铁研究总院、中国科学院化冶所以及全国各大钢厂等十五个单位的二十多名科技人员参加对首钢炼钢厂研制的单流道二次燃烧氧枪进行了技术鉴定。转炉二次燃烧氧枪是在普通顶吹氧枪上增加二次氧流,以一定比例向炉内供氧,把熔池上面的一氧化碳部分燃烧成二氧化碳,并将产生的热量传递
From August 21 to August 23, 1986, the Ministry of Metallurgy organized more than 20 scientific and technical personnel from Beijing Iron and Steel Institute, China Iron and Steel Research Institute, Chinese Academy of Sciences, China Metallurgical and Metallurgy Institute and other 15 major steel mills in China to participate in the first steelmaking Steel developed a single-channel secondary combustion oxygen lance technical appraisal. BOF secondary oxygen lances are used to increase the secondary oxygen flow in a conventional top-blown oxygen lance to supply oxygen to the furnace in a certain proportion. The carbon monoxide above the molten pool is partially combusted into carbon dioxide and the generated heat is transferred
