铁水经过加镁球化处理及加矽铁墨化处理以后,为了快速鉴别水是否球化,及时进行浇铸,我厂发现用火焰可以来鉴别铁水的球化情况。球墨铸铁是在容量为700公斤的铁水包中处理的,当加镁及加矽铁以后,要将大包中的铁水倒入抬包中,当铁 Hot metal after magnesium plus spheroidization and add ferrosilicon after treatment, in order to quickly identify whether the water is nodular, timely casting, I found the flame can be used to identify the hot metal spheroidization. Ductile iron is processed in a capacity of 700 kg of hot metal ladle, when plus magnesium and add ferrosilicon later, the large package of molten iron into the lorry, when the iron
