日本神户制钢所利用改建的转炉发展了一种铁水预处理新技术。1983年11月,该技术已成功地用来生产大批量的高等级钢水。这种铁水预处理炉容量为80吨,配备两个从顶部插入的喷枪,分别用来喷吹脱磷或脱硫剂和氧气。在精炼的第一阶段采用顶吹氧气和喷吹石灰-铁氢化物系熔剂(CaO-轧钢屑-CaF_2)及从顶部添加锰矿石、块状生石灰和转炉渣等进行铁水脱硅和脱磷,其后则
Japan’s Kobe Steel used the converter to transform a new hot metal pretreatment technology. November 1983, the technology has been successfully used to produce large quantities of high grade molten steel. This hot metal pretreatment furnace has a capacity of 80 tons and is equipped with two spray guns inserted from the top for spraying dephosphorization or desulfurization agents and oxygen respectively. In the first stage of refining, desliming and dephosphorizing of hot metal were carried out by using top-blowing oxygen and jetting lime-ferric-hydride flux (CaO-rolling steel-CaF2) and adding manganese ore, massive quick lime and converter slag from the top, Followed by
