摘　　要：简要介绍了唐钢150 t转炉双渣冶炼技术工艺试验的研究分析,结合不同吹炼时期冶炼特点,确立了操作控制的关键措施,对倒炉温度、碱度、炉渣中的FeO和MgO含量及熔渣流动性等因素的合理控制,是取得良好脱磷效果的重要保证,运用控制轻烧白云石加入造渣的双渣生产试验使唐钢取得了良好的经济效益。This paper describes the research and analysis of 150 t converter double slag smelting process, test in Tangsteel, and combines with metallurgical characteristics of different blowing period, establishing the key measures of operational control. The reasonable control of the content and the slag liquidity of FeO and MgO in furnace temperature, alkalinity, slag are important guarantee to achieve good results of dephosphorization. The use of controlled light burned dolomite with double slag production test makes Tangshan Iron and Steel achieve good economic results.
