Direct Reduction Process An Overview Sciencedirect Topics

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 Iron HBI and Cold Briquetted Iron CBI; also Low Reduced Iron
