Web23 dec. 2024 · The shaft furnace is fed with pellets or lump ore at the top, which descend by gravity and encounter a rising flow of H2, fed laterally at mid-height of the reactor and exiting at the top. The reduction reactions take place in the upper section between the reducing gas outlet and inlet. WebThe Corex Process is a smelting reduction process created by Primetals as a more environmentally friendly alternative to the blast furnace. Presently, the majority of steel production is through the blast furnace which has to rely on coking coal. That is coal which has been cooked in order to remove impurities so that it is superior to coal. [1]

WebA process for the production of direct reduced iron (DRI), with or without carbon, using hydrogen, where the hydrogen is produced utilizing water generated internally from the process. The process is characterized by containing either one or two gas loops, one for affecting the reduction of the oxide and another for affecting the carburization of the DRI. WebDirect reduction of iron ore with hydrogen DRI is a manufacturing process to produce steel using hydrogen to reduce iron instead of coking coal. Hydrogen is used as the main reduction agent in the process of making sponge iron through the direct reduction of iron ore in a shaft furnace.
