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.

Direct Reduced Iron and its Production Processes –

2013-3-16  DRI production process. The DRI production process involves the intimate mixing of prepared (sized) iron ore with a reductant, which is also generally used for heating of the ore bed to the temperature needed to achieve adequate reduction rates. The reductant can be a gas or a solid. Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore

MIDREX Processes - KOBELCO

2011-1-6  The MIDREX process produces direct reduced iron (hereinafter referred to as DRI ). The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed.
