  • Process for feeding heat energy into a molten metal bath
    Patent number: 4881972
    Abstract: Solid carbon and solid metal materials, preferably scrap, which are to be melted, are introduced into a crucible which accommodates a molten metal bath, and oxygen is blown into the molten metal through nozzles or lances. Better utilisation of the carbon is achieved by the carbon being charged into the crucible in the condition of being packed in sheet metal containers, the sheet metal containers being pressed into the molten bath by solid metal materials lying thereupon when the oxygen is injected.
