Direct reduced iron production

Use: In electrometallurgy, direct-reduced iron is exclusively used as a source of iron for steelmaking. It is a major and very serious contender for scrap and pig iron. A further DRI twist is provided by its development inextricably linked with that of electric steel production. Average annual growth rate of DRI production is estimated at 9 %

    BASED DIRECT REDUCED IRON – SHAFT FURNACE How it works: Instead of a carbon reductant such as coke, H 2 is used to reduce iron ore pellets to direct reduced iron (DRI, or sponge iron). The reaction takes place in a shaft furnace, a type of furnace that uses gas reductants to make DRI. The operating temperature can be fairly low, around 800 C

    Jan 05, 2012 Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of natural gas
