Overview | ISPCFormation of DIRECT REDUCTION IRON CO. DIRECT REDUCTION IRON CO. was founded. 2006: AL ITTEFAQ STEEL II – Makkah: Acquisition of the Azizya Steel Factory, which had a steel rolling capacity of 100,000 tons per annum. Following acquisition, its capacity was increased to 360,000 tons per annum,with 150,000 tons per annum downstream capacity. 2006
Direct reduced ironProcess. Direct reduction processes can be divided roughly into two egories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
Direct reduced ironDirect 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 below the melting ...
Use of Direct Reduced Iron in Electric Arc Furnace – IspatGuru · Direct reduction can be defined as reduction in the solid state at O2 potentials which allow reduction of iron oxides, but not of other oxides (Al2O3, MnO, and SiO2 etc.), to the corresponding elements. Since reduction is in the solid state, there is very little chance of these elements dissolving (at low thermodynamic activity) in the reduced iron, so the oxides which are more stable than ...

North Africa: Focus on Direct Reduction Ironmaking ...Direct reduction of iron – extracting metallic iron from iron ores without melting the material – is one of the first industrial processes developed by humans. Early ironmakers were unable to achieve the high temperatures required to melt iron ores, so they heated them together with charcoal to produce a pasty, metallic substance which they could hammer into tools and other implements ...

DirectReduced IronDirect 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 (, Mexico produces virtually all ...
Direct Reduced Iron (DRI) | International Iron Metallics ...Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. See more information about the production of DRI. Most gasbased direct reduction plants are part of integrated steel minimills, loed adjacent to the electric arc furnace (EAF) steel plant. DRI can be either hot or cold charged to ...
