据日本《日经产业新闻》报道,最近日本住友金属工业公司研究成功了一项使用转炉采熔化废铁的新方法。据称,这是一种有效地利用焦炭、不必使用高炉产生的铁水、只将废铁进行熔化的方法。目前,转炉炼钢法使用废铁的比率为10％左右。高炉厂家为了增加废铁的使用量,长期实施了转炉中除使用高炉产生的铁水之外,同时还投入焦炭,将废铁熔化的方法。
According to Japan’s Nikkei Business News, Japan’s Sumitomo Metal Industries recently succeeded in finding a new method using converter melting of scrap iron. Allegedly, this is an effective way to use coke, without having to use the molten iron produced by the blast furnace, only to scrap iron melting method. At present, the converter steelmaking method using scrap iron ratio of about 10%. In order to increase the amount of iron scrap used, blast furnace manufacturers have long implemented a method of melting scrap metal by adding coke to the converter in addition to the hot metal used in the blast furnace.
