一、前言众所周知,为了提高铁水质量和铸件成品率以满足高牌号灰铸铁,特别是合金铸铁日益发展的需要,用感应炉易得到高温过热的铁水,铁水中氧化夹杂物少,化学成份均匀,且容易控制,然而人们在生产实 First, as we all know, in order to improve the quality of hot metal and casting yield to meet the high grade gray cast iron, especially the growing needs of alloy cast iron, easy to get high temperature overheating with induction furnace hot metal, molten iron less oxidizing inclusions, chemical composition, And easy to control, but people are producing real
