摘要： A method and an apparatus, wherein heat can be effectively transferred to molten metal (12) contained in a reaction vessel. The pressure of gaseous atmosphere (16) within the vessel is maintained higher than atmospheric pressure. Oxygen gas is blown to a layer (14) of molten slag contained in the vessel through tuyeres set in the reaction vessel, thereby to achieve post-combustion therein. The pressure in the vessel is controlled within the range of 2.0 to 5.0 kg/cm 2 by pressure regulator (26).
