WebIron Ore Lump, Ferrous Sulphate Pellets & Iron Ore offered by Bagalkot Steel Tradersfrom Bagalkot, Karnataka, India WebSince the 1970s, direct reduction (DR) processes, which rely on natural gas rather than coal or coke, have emerged and gained traction. In DR processes, iron ore in the form of lumps, pellets, or fine powder is reduced in the solid state to direct reduced iron (DRI), which is thereafter converted to steel in an electric arc furnace (EAF).

WebOct 25, 2013 · The results were compared to that of reformed natural gas (RNG), which is already applied in the commercial direct reduction processes. The reduction of lump ore was carried out at temperatures in the range of 1073 K to 1323 K (800 °C to 1050 °C) to simulate the reduction zone in direct reduction processes. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
