direct reduction process

11/3/2016· The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.

SPONGE-IRON - Shakambhari Group

In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).

DRI production | International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
