上钢一厂平炉冶炼高碳钢较多,在炉料溶清后约有8％炉数的熔毕碳偏低,通常采用铁水增碳。装入量达100吨的平炉,增碳铁水约需七吨左右,往往使出钢量超过钢包容量,很不安全也不合理。为了解决这一问题, The upper steel plant flat furnace smelting high-carbon steel more, after the charge is clear about 8% of the furnace number of low carbon melting, the commonly used hot metal by carbon. Loading capacity of 100 tons of open hearth, about seven tons of molten iron, often make the amount of steel over the ladle capacity, it is not safe or reasonable. In order to solve this problem,
