27/4/2016· Another alternative to hot molten iron making is the direct reduction method. In this method, iron is reduced in its solid state using either coal or natural gas as a fuel. One advantage of this method is that iron can be added as lumps, pellets, or fines, and if coal
The direct reduction process uses palletized iron or natural ‘lump’ ore. Process Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tuled with a ‘select’ grade of iron-coking coal little dolomite inside an inclined rotary kiln
Process Description. R&D Trends. In a direct reduction process, lump iron oxide pellets and/or lump iron ore, are reduced (oxygen removed) by a reducing gas, producing direct reduced iron (DRI). If the cooling stage is omitted, the DRI can be immediately briquetted into hot briquetted iron (HBI). The reducing gas can be generated externally to
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.
The Midrex ® direct reduction process is the industry’s most productive technology for making high-quality direct reduced iron (DRI) products, accounting for approximately 60% of the world’s total annual production. DRI and its derivatives, including hot briquetted iron (HBI), are a iron feedstock that is often used in steelmaking

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.
Direct-reduced iron (DRI), also called sponge iron, 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 (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron

In a 2 stage-smelting reduction process, it is favorable to lower the reduction degree of iron ore in a pre-reducing unit by lowering its temperature to avoid any troubles due to stickiness of high reduced iron ore. However, less pre-reduced iron ore can induce direct
The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes. The noncaking coal is

14/8/2020· Iron making The primary objective of iron making is to release iron from chemical coination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here.Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
The present invention concerns a process and a apparatus for the direct reduction of iron ores by gaseous agents resulting from the alytic conversion of methane. Several processes are known for the direct extraction of iron from ores, these methods attempting to replace the blast-furnace reduction method which uses as the reducing agent relatively scarce metallurgical coke.
