Sponge Iron (DRI) | The Hira GroupCoal based Spongeiron is a metallic product produced through direct reduction of iron ore in the solid state .As such it is also known as Direct Reduced Iron (DRI). Iron Ore Pellet is used for reduction.
Suspended Hydrogen Reduction of Iron Oxide Concentrates ...Suspended Hydrogen Reduction of Iron Oxide Concentrates The ultimate objective is to eliminate or drastically reduce the generation of CO 2 in the steel industry. The process would use gaseous reducing agents, such as hydrogen, natural gas, a reducing gas generated by partial combustion of coal or waste plastics, or a combination thereof.
Process Analytics in the Iron and Steel IndustryDirect reduction is a gasbased ironmaking technology, using natural gas instead of coke. The natural gas reacts with CO 2 to CO and H 2. The CO then acts as reducing agent. Smelt reduction technology is a coalbased iron making process. Smelting reduction technology, as the name clearly suggests, involves both solidstate reduction and ...

The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called
A study on the accretion formation in DRI kilns and ...processes) producing slagfree pig iron. On the other hand, direct reduction processes include reduction of iron oxides in the solid state, below the fusion temperature of pure iron (1535o C), utilizing hydrocarbon gases and or carbonbearing materials as reducing–carburizing agents.
Investigation of Chemical Looping Combustion by Solid ...CuO reduction by solid fuels can start at temperatures as low as approximately 500 °C. Tests indicated that the solid fuels with higher reactivity (higher volatile matter) would be desirable for the development of the chemical looping combustion process of solid fuels, such as subbituminous Powder River Basin coal and solid waste and biomass.
Al Buraq Steel Industry Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore.
