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 .
Iron And Steel Production
Iron And Steel Production ... Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the blast air to form molten reduced iron, carbon monoxide .

Hydrogen in steel production: what is happening in Europe ...
· Iron ore is reduced with hydrogen while in a solid state, hence the name direct reduction, to produce direct reduced iron (DRI) called sponge iron. Sponge iron is then fed into an EAF, where electrodes generate a current to melt the sponge iron to produce steel. Some carbon is needed so that steel can be produced. This carbon can come from ...

/ Plasma direct steel production / Electrolytic processes 3 A SOLID SOLUTION ... 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 .
Sponge Iron Production By Direct Reduction Of Iron Oxide ...
This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is 'directly reduced' in the solidstate, using either natural gas or noncoking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces ...

Sponge iron, also called Directreduced iron (DRI),[2] is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H 2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the ...
Modelling and optimization of a rotary kiln direct ...
In this paper the direct reduction of iron ore to sponge iron is used as an example. The model incorporates a large number of variables, covering, among others: feed properties and rates, combustion options, kiln operating information (speed and fill level), blower loions and flow rates, and the environmental conditions. Due to the high level of detail included in the model, a .

first sponge iron refining process/beneficiation of raw materials in comminution and magnetic separation, due to the local iron ore raw materials are still many impurities which would lead to lower levels of iron in the material standard so that the standard product manufacture sponge iron will be difficult to achieve if there are impurities in the raw materials. The following are .
Direct reduced iron
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) into iron by a reducing gas or elemental carbon produced from natural gas or ores are suitable for direct reduction. Direct reduction refers to solidstate processes which reduce iron oxides to metallic iron at temperatures .
