摘　　要：研究了Cr-Cu合金灰铸铁在有覆盖剂的情况下,中频感应电炉熔炼过程中合金元素的烧损规律。研究表明:在有覆盖剂覆盖的中频感应电炉熔炼条件下,铁液熔化温度在1400～1500℃之间时,铁液中的C、Si、Mn、P、S、Cr、Ni、Cu、Mo、Ti的含量基本不变;高于1500℃,铁液中的C稍稍下降而Si含量稍稍升高,其它合金元素依然未发生变化。作者解释了出现上述现象的原因。Burning rules of elements in Cr-Cu alloy cast iron have been studied in MF induction furnace melting with covering agents.Studies showed that in such condition and at melting temperature between 1400℃-1500℃,C,Si,Mn,P,S,Cr,Ni,Cu,Mo,Ti content in molten iron was basically unchanged.At higher temperature than 1500 ℃,in the molten iron C content slightly decreased while the Si content increased slightly,and other alloying elements remain unchanged.The above phenomenon has been explained.
