MEANS FOR EXTRACTING AND REFINING METAL | 2 |
| 20150061200 | Apparatus for making liquid iron and steel - A metallizing apparatus which is carbonaceous-based 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. | 03-05-2015 |

Iron ore powder, coal powder, and other such raw materials supplied into the reactor are irradiated with microwaves from microwave oscillators and are heated. The iron ore is reduced, and the resulting molten pig iron flows out through a hole into a crucible, and then is poured out of the crucible through another hole into a ladle. It is thereby possible to manufacture molten pig iron with high energy efficiency, instead of using blast-furnace iron-making. | 02-12-2009 |
