Direct Reduced Iron (DRI Steel)
Description of Direct Reduced Iron (DRI Steel)
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore(in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for making direct reduction iron.
Direct reduction refers to solid-state processes that reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C in the presence of the reducing gas syngas, a mixture of hydrogen and carbon monoxide. DRI, dri direct reduced iron, is produced through the removal (reduction) of oxygen from iron ore in its solid-state. This technology encompasses various processes based on different feedstocks, reactors, and reducing agents. DRI processes can reduce CO2 emissions by using natural gas instead of coal due to the replacement of carbon reductant by hydrogen from methane.
Basic characteristics of Direct reduced iron (DRI)
Direct Reduced Iron Process
Indirect reduction plant, the oxide pellets produces in the dri in steel plantenters the reduction plant from the top into the furnace after it has had its chemical and physical properties checked, and loses its oxygen to the reducing gas which flows upwards from the bottom of the module.H2 and CO and H2O is the initial mixture of the reducing gas with the radio of 1.5 to 1.7. This mixture absorbs the oxygen content of the pellets and changes into CO2 and H2O and gets out of the furnace from the top.
