Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of connecting pores ...
Malcolm Tatum Sponge iron is created from iron ore. Sometimes known as directreduced iron, sponge iron is a product that is produced using iron iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source.
· In a plasma fired iron ore induration furnace, from conduit 10 providing hot recuperated air from the pellet cooling zone, there would be a plurality of downcomers 11, or conduits 21, leading to the laterally extending tunnels 14, or shafts 24, where the hot recuperated air would be mixed with the extremely hot air heated by the plasma torches 12, or 22, before entering the firing chamber 13.
Sponge iron powder . The Höganäs process is a direct reduction method for production of sponge iron powder using magnetite ore (Fe3O4) and carbon as raw materials. The reduction process takes place in a gas fired tunnel kiln at around 1200°C for 60 hours producing a sponge iron cake that is crushed, milled and magnetically separated from impurities. The final reduction is made in a ...
In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced iron is melted in the melter–gasifier vessel. Reducing gas (CO and H 2) used in the reduction shaft is supplied by gasifiion of coal by means of oxygen, forming a fixed or fluidized bed in the melter–gasifier ...
In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial ...

· Sponge iron is then fed into an EAF, where electrodes generate a current to melt the sponge iron to produce steel. Some carbon is needed so that steel can be produced. This carbon can come from pulverized coal, biomethane or other biogenic carbon sources. This, combined with electrode consumption, adds up to ±53 kgCO 2 per tonne of steel – if the electricity used is not fully renewable, .
