Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace.

Sieurin invents sponge iron method The Höganäs Method is invented by engineer Emil Sieurin. The method means reducing iron ore with the help of coke, lime and clay. After patenting the method, Höganäs starts production in 1911 and in 1912 a plant is built. Later on, Höganäs will start grinding the reduced iron to powder, sponge iron powder.
