direct reduction process

in iron processing: Direct reduction (DR) This is any process in which iron is extracted from ore at a temperature below the melting points of the materials involved. Gangue remains in the spongelike product, known as directreduced iron, or DRI, and must be removed in a subsequent steelmaking process.

Finex is an innovative ironmaking process based on the direct use of fine ore and noncoking coal. In the Finex process, fine iron ore is directly charged at the top of a cascade of fluidizedbed reactors, where it is heated and reduced to directreduced iron (DRI) by means of a reduction gas derived from the gasifiion of the coal in the melter gasifier.

 · Most primary production occurs through the blast furnace–basic oxygen furnace (BFBOF) route, though a smaller amount of primary steel is produced from direct reduction of iron (DRI) followed by processing in an electric arc furnace (EAF). Most secondary production, which is less energy intensive, occurs in an EAF.

direct reduced iron process

Direct reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (, natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed.

In direct reduction processes iron oxide is reduced to iron. The resulting product named Direct Reduced Iron (DRI) has a high content of metallic iron and of low content of carbon. Being used as raw material for high quality steel making in the Electric Arc Furnace, DRI is gaining increasing prominence as feedstock for this process.
