Abstract:
     This invention relates to a method for the production of molten steel. It features that iron ore and coal are continuously added into the molten metal, whose carbon content is equal to or less than 1%, while the molten metal is oxygen-blown by an oxygen lance; at the same time of doing above operations, a stirred gas is blown into the molten metal via gearth jets with the flow of 0.05-0.5 Nm to the third/min/ton molten metal. The manufactured scoria and molten steel can be continuously or periodically poured-out.
