    Jun 21, 2018 In the direct-reduced iron (DRI) process, the iron ores are reduced directly to sponge iron by gaseous reducing agents! Electro-steel process. In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process.

  • Direct Reduction Process An Overview Sciencedirect Topics

    The direct reduction processes in combination with the melting of directly reduced iron to produce steel in the EAF offer an alternative to the BF-BOF route. The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted …

  • Direct Reduced Iron Industrial Efficiency Technology

    Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces.

  • Direct Reduction Of Iron Ore Springerlink

    Nov 27, 2014 In the search for a pure, available iron source, steelmakers are focusing their attention on Directly Reduced Iron (DRI). This material is produced by the reaction of a low gangue iron ore with a hydrocarbonaceous substance. Commercially, DRI is generated in four different reactors: shaft (moving-bed), rotary kiln, fluidized bed, and retort (fixed-bed).
