| 摘要 |
A method for producing steel, particularly for producing steel with electric furnaces, comprising a step of charging ferrous material in a melting furnace, a melting step during which heat energy is supplied to the ferrous material to raise its temperature to a level that is higher than the melting temperature, and a step of refining the liquid steel produced by the melting of the ferrous material. A simultaneous injection of methane or of another hydrocarbon and of oxygen in the bath of liquid steel is performed, at least during the refining step, in replacement of the coal fines and/or sized coal that are conventionally used. <IMAGE> |
