高炉铁水炉前直接浇铸,是早已被人们所倡导的一项节能新工艺。多年来不少单位为实现炉前铸造曾做过种种尝试和很大努力。然而,由于一些具体技术问题没有得到合理解决,加之高炉铁水温度低,杂质多,化学成份波动较大等原因,至今成效甚微。中小铁厂经营亏损和焦炭的日趋紧张,高炉—工频炉双联工艺应运而生。双联新工艺的成功,为实现炉前铸造开辟了新的途径。一、双联的理论依据 Blast furnace hot metal casting directly before, is already advocated by people as a new energy-saving process. Over the years many units have done all sorts of attempts and great efforts to realize the casting in front of the furnace. However, due to some specific technical problems have not been properly solved, combined with low temperature of hot metal blast furnace, impurities and more volatile chemical composition and other reasons, has achieved little success. Small and medium-sized iron mills operating losses and coke increasingly tense, blast furnace - industrial frequency furnace double process came into being. The success of the new twin process has opened up new avenues for casting in the furnace. First, double the theoretical basis
