Iron and Steel Industry | The Canadian EncyclopediaSolidstate reduced ore and/or pellets, known as DRI (Direct Reduced Iron), are melted in electric arc furnaces and converted to steel in the same way as scrap metal. During the steelmaking process, the gangue in DRI is removed; the gangue minerals contained in DRI .

It reviews the present status of the direct reduction (hereinafter referred to as "DR") technology at Kobe Steel and examines the role played by DRI in achieving a paradigm shift in the iron and steel industry. 1.
What is the difference between sponge iron and billets ...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. It is a substitute for scrap and is mainly used in making steel through the secondary route.
Direct Reduced Iron |authorSTREAMIntroduction of DRI Sponge iron is a term given to the product obtained by reduction of iron ore in solid state. Sponge iron is a mixture of reduced metallic iron, unreduced iron oxide and the associated with gangue constituents of the original ore.
Coal in the sponge industryof coal firing are used, namely, a) Direct firing and b) Indirect firing. Coal in an essential component in production of sponge iron. Coal based direct reduction technologies involve reduction of iron oxides in a rotary kiln by using noncoking coal as a reducing agent. .

Reduction Kinetics of Egyptian Iron Ore by Non Coking CoalAbstract: Reduction kinetics of ElBaharia iron ore by solid coal briquettes in liter/min nitrogen flow rate were investigated at different temperatures ranging from 700˚C to 950˚C. It was found that the best reduction properties were found at 950˚C, so the kinetic models weredetermined.
Energy Audit Methodology of Sponge Iron Manufacturing ...Most of the plants in India use DRI process—a solid state direct reduction process by which iron ore is reduced to sponge without phase change (Figure 1). Raw material mixiron ore, dolomite and coal are fed to one end of rotary Kiln and product sponge iron along with char is taken out from the other end. Apart from this, primary
