Historically, the operation of an electric arc steelmaking furnace has been an intermittent operation, wherein the sequence followed is: charging of steel scrap and/or direct reduced iron, pig iron, slag formers and alloying elements; ignition or establishment of an electric arc between the electrodes in the furnace to create melting conditions for melting the charge and forming a molten metal bath covered …

processed ferrous metal and process of production

Processed low carbon iron metal and process and apparatus for its production, using high water-vapordecarburization, are provided. The iron metal product is characterized by fine grain structure with average carbon content less than about 0.04%

cogeneration process for production of energy and iron

Iron material, such as ore, is fed into a separate chamber, wherein it is exposed to hot coal gas from the melter/gasifier. The reduced ore material is then fed directly into the melter/gasifier wherein it is melted, and drawn off as pig iron. This pig iron material may be refined to steel, as described below
