Direct Reduced Iron and its Production Processes IspatGuru

Mar 16, 2013 Fig 1 DRI process principle. Major DRI production processes are either gas based or coal based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor, the reduction reaction takes place is a shaft furnace.

MIDREX Processes kobelco.co.jp

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

GASIFICATION AND THE MIDREX? DIRECT REDUCTION

The production of direct reduced iron (DRI), a basic raw material for making steel, is concentrated in a few countries in the Middle East and Latin America. One primary reason is that natural gas, the main fuel source for most DRI processes, is too costly in many of the steel making regions of the world.

Steelmaking Wikipedia

Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladles.
