摘　　要：以年产10万t灰铸铁缸体、缸盖铸件的车间为对象,针对铸造生产是采用冲天炉+保温电炉的双联熔炼方式还是采用中频感应电炉的单一熔炼方式问题,从熔炉自身特点、对原料要求、余热利用可行性、操作维护难度、投资及运行成本等方面进行了综合对比;认为,虽然冲天炉的初期投资较高,但其熔化运行成本低、对炉料要求低、供液连续、铁液冶金性能好、余热和固体排放物可回收利用、能源消耗少,建议采用冲天炉+保温电炉双联熔炼方式。With a foundry shop having productive capacity of 100 000 t of gray iron cylinder block and cylinder head castings as object of analysis,the problem whether the cupola ＋ electrical holding furnace duplex melting or the single medium frequency induction furnace melting to be adopted for the casting production was comparatively analyzed in the aspects of the characteristics of melting furnace itself,raw materials requirements,usage possibility of the afterheat,operation and maintenance difficulties, investment and running cost, etc. It was considered that, although the initial investment of the cupola is relatively higher,however its melting running cost is lower,its melting charge requirements are lower,it can supply molten iron continuously,metallurgical properties of its molten iron are better, its afterheat and solid emissions are reusable,its energy consumption is less. It was suggested finally to adopt the cupola ＋ electrical holding furnace duplex mehing.
