在采用冲天炉或双重熔炼法的马铁车间中,利用矽铁的孕育作用,可能建立高级孕育铸铁的制造工作。这项工作已经由“红色阿克塞”工厂中所进行的研究而证实了。在研究的同题中,包括:当铸件直径为30、60、90和120公厘时,矽铁最适当的加入量;浇铸温度及孕育剂的加入量对铸铁金相组织及机械性能的影响;当与正常的化 In the use of cupola or double melting method of the horse iron workshop, the use of ferrosilicon inoculation, may establish the manufacture of advanced inoculation of cast iron. This work has been confirmed by research carried out at the “Red Axel” plant. In the study of the same title, including: when the casting diameter of 30,60,90 and 120 mm, the most appropriate addition of ferrosilicon; casting temperature and the addition of inoculants on the cast iron microstructure and mechanical properties When normalized
