More Information
Summary:A carbonaceous-based metallizing method and apparatus wherein a metallic oxide is converted into a carbon-containing, metallized intermediate that is melted in an induction channel furnace to produce liquid metal from said metallic oxide. In the application of iron ore in the form of fines or concentrate, using low-cost coal will greatly reduce capital and operating costs by virtue of eliminating agglomeration of ore, cokemaking, and blast furnace operation. The liquid iron so produced is efficiently converted into steel in a steelmaking furnace such as a basic oxygen furnace (BOF), especially when it is physically integrated to the induction channel furnace wherein the liquid iron is directly poured into the integrated BOF by the induction channel furnace, producing low-cost steel, little heat loss, and minimum emissions.
