碳素锰铁是含有少量 Si、P、S 杂质的 Mn—Fe—C 三元合金。它用于炼钢上作脱氧剂和合金添加剂,是炼钢上用量最大的一种铁合金。碳素锰铁可在高炉或电炉中熔炼。我国生产的碳素锰铁有相当一部分是在电炉中熔炼的。电炉熔炼炭素锰铁有无熔剂法和熔剂法之分,无熔剂法是炉料中不加熔剂(石灰)并使用不足的还原剂(焦炭)控制锰的还原,使之既能得到含 Mn>35%的低磷富锰
Carbon ferromanganese is a Mn-Fe-C ternary alloy containing a small amount of Si, P, S impurities. It is used for steel making deoxidizer and alloy additives, is the largest amount of steel on the iron alloy. Carbon ferromanganese can be melted in a blast furnace or electric furnace. A considerable part of the carbon ferromanganese produced in our country is smelted in an electric furnace. Melting carbon ferromanganese furnace with or without flux method and the flux method of points, no flux method is the furnace without flux (lime) and the use of less reducing agent (coke) to control the reduction of manganese, so that both can get Mn> 35 % Of low phosphorus rich manganese
