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 LRI , which is ...
