摘　　要：介绍了中频炉与AOD精炼炉联合冶炼ZG07Cr19Ni9Mo的工艺流程及熔炼过程参数控制措施。通过中频炉冶炼为AOD炉提供粗炼钢水,结合AOD炉精炼工艺,降低了中频炉对原辅材料的使用标准,采用吹氮气的方式进行钢液增氮,减少了氮化合金的加入量,经实际生产验证钢液纯净度高,夹杂物含量低,生产效率高。This article introduces the process flow and parameter control measures for the joint smelting of ZG07Cr19Ni9Mo using a intermediate frequency furnace and an AOD refining furnace.The intermediate frequency furnace smelting is adopted to provide rough molten steel for AOD furnace,combined with AOD furnace refining process,the standard for the use of raw and auxiliary materials in intermediate frequency furnace is lowered.Nitrogen is blown into the molten steel to increase nitrogen and reduce the amount of nitralloy added.Through actual production verification,the purity of the molten steel becomes higher,the content of impurities is lower,and the production efficiency is higher.
