一、前言近年来气体稀释脱碳法和真空脱碳法的发展,使钢液优先脱碳的炼钢技术取得了重大进步,在生产不锈钢时可以使用高碳炉料,因而对原料要求的灵活性有了飞跃的提高,大幅度地降低了不锈钢的生产成本。特别是复合吹炼转炉炼钢和铁水预处理技术的进步,有些转炉炼钢厂家也都积极发展利用复合吹转炉精炼不锈钢的新工艺,日本川崎钢铁公司千叶厂发展的K-BOP法,即川崎碱性氧气转炉法,就是其中最典型的一个例
I. Introduction In recent years, the development of gas dilution decarburization method and vacuum decarburization method has made significant progress in the steelmaking technology that preferentially decarburization the liquid steel, and the high-carbon charge material can be used in the production of stainless steel, thereby requiring the flexibility of raw materials With the leap of improvement, greatly reducing the cost of stainless steel production. Especially the compound blowing converter steelmaking and hot metal pretreatment technology advances, and some converter steel manufacturers are also actively developing the use of composite blower refining stainless steel new technology, Japan’s Kawasaki Steel Chiba plant developed K-BOP method that Kawasaki basic oxygen converter method, is one of the most typical example
