Direct Reduction Process

Direct Reduction Process

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 pre .

Sponge Iron

Sponge Iron

DRI also known as sponge iron is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace rotary kiln or fluidized beds in the form of pellet iron ore lumps or fines. The reduction takes place using gaseous reductants CO H .

Model And Simulation Of A Ported Kiln For Iron Oxide

May 19 2008 A mathematical model of a ported kiln for iron oxide pelletizing was developed to simulate the effects of under‐bed air injection on kiln fuel requirements and magnetite oxidation. A tanks‐in‐series model was used to set up material and energy balance equations for countercurrent flow of solids and gas through the kiln.
