HEAT BALANCE CALCULATION FOR MC FERROMANGANESE PRODUCTION IN "EIGHT ONE METHOD"

论述了"八一法"生产中碳锰铁新流程的热平衡计算,为该新工艺的实施及节能降耗提供了理论依据。新工艺采用两个摇包实现锰硅合金的3次脱硅,将精炼炉作为提供热量的化渣炉,从而得到合格的中碳锰铁。热平衡计算结果表明:依靠炉料显热和化学热,采用两个摇包3次连续脱硅生产中低碳锰铁的新工艺可行,且不会出现摇包冻包现象。

This paper focuses on the heat balance calculation for new process of producing medium carbon ferromanganese with＂Eight One Method＂,provides the theoretical basis for the implementation of this new process and energy-saving and consumption-reducing.The new technology uses 2 shaking ladles to finish the desiliconization for 3 times of silicomanganese, uses the refining furnace as slag-melting furnace to offer heat,thus the qualified medium carbon ferromanganese is obtained. The heat flow contains 3 types which are sensible heat,hear of chemical reaction,heat absorbed by lining of furnace and heat emission from the furnace body.The heat balance calculation results show：it is feasible to produce medium carbon ferromanganese with the new process of continuously desiliconizing in 2 shaking ladles for 3 times depending on sensible heat and chemical heat burden,the ladle-freezing can not occur.
