目前,世界上有些小钢厂参予了高品质钢材的生产。为生产高级钢,增加了高品质废钢的使用量。由于高品质废钢较为短缺,因此,提高了高级废钢的价格。 还原铁和生铁能稀释废钢中的杂质,这样,既可使用一般废钢,又可用生铁和还原铁代替一部分废钢。 目前,内陆钢公司的电炉使用还原铁的比率已达10～20％;纽柯公司用还原铁和生铁置换15％的废钢。 纽柯公司认为碳化铁的生产成本低,又便于搬运,因此,为了自己生产代用炉料,在特立尼达和多巴哥建设了碳化铁厂,年产能力为30万吨。
At present, some small mills in the world are involved in the production of high-quality steel. For the production of high-grade steel, increased use of high-quality scrap. Due to the shortage of high-quality scrap, the price of advanced scrap has been raised. Reduced iron and pig iron can dilute scrap impurities, so that you can use the general scrap, but also use pig iron and reduced iron instead of part of the scrap. At present, inland steel companies use 10% to 20% reduction of EAF and Nucor uses 15% reduction of scrap and pig iron. Nucor considers the production cost of iron carbide to be low and easy to handle, so that in order to produce its own charge, it has built an iron carbide plant in Trinidad and Tobago with an annual capacity of 300,000 tons.
