在铸造车间配制不同牌号的铁水各有一定的炉料配比,除非要求铁水有新的成分需要变动配比以外,在通常的情况下配比是固定下来的。这样化铁炉熔炼的配料,实际上常常是计算由于炉料中硅量和标量的不足,应向炉内补充硅铁和锰铁的数量。除去铁合金外常用的金属炉料不外是生铁,回炉铁,废钢。各级回炉 In the foundry to prepare different grades of molten iron have a certain ratio of charge, unless the need for a new composition of molten iron need to change the ratio, the ratio is fixed under normal circumstances. In fact, the ingredients of smelting iron smelter, in fact, often calculate the amount of ferrosilicon and ferromanganese that should be added to the furnace due to the lack of silicon and scalar quantities in the charge. Remove the commonly used outside the iron alloy metal charge is nothing but pig iron, iron back, scrap. At all levels to return
