摘　　要：总结归纳了当前不同原料条件下300系不锈钢冶炼工艺流程。根据原料结构的不同,目前广泛应用的300系不锈钢冶炼流程有5种。概述了5种300系不锈钢冶炼工艺流程的优缺点,并结合生产数据分析5种冶炼工艺路径的成本差异。结果表明,全冷料冶炼时,中频炉(IFF)流程具有成本优势;相比全冷料冶炼,以小高炉镍铁水或矿热炉(RKEF)镍铁水为主要原料的工艺流程成本更优;而所有的原料构成中,采用矿热炉镍铁水作为主要原料是最具有成本竞争力的工艺流程。研究结果可为300系不锈钢生产原料和工艺流程的选择提供参考。The common 300 series stainless steel smelting process under different raw material conditions was summarized.According to the different raw material structure,there are five kinds of 300 series stainless steel smelting processes widely used at present.The advantages and disadvantages of five kinds of 300 series stainless steel smelting processes were summarized,and the cost differences of five kinds of smelting processes based on production data were analyzed.The results show that the process of intermediate frequency furnace has cost advantage in the process with total cold raw materials.Compared with total cold raw materials,the process cost is better when the main raw material is nickel hot metal in small BF or RKEF(rotary klin electric furnace).Among all the raw materials,the most cost-competitive process is to use nickel hot metal of RKEF as the main raw material.The research results of this paper can provide reference for the selection of raw materials and process flow of 300 series stainless steel production.
