Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

Use: In electrometallurgy, direct-reduced iron is exclusively used as a source of iron for steelmaking. It is a major and very serious contender for scrap and pig iron. A further DRI twist is provided by its development inextricably linked with that of electric steel production. Average annual growth rate of DRI production is estimated at 9 % ...

"When I moved to this lovely 2-1/2 acre parcel of land, I was elated. Then mowing season came. I must of destroyed 7 or 8 different types of power equipment. Then I bought the DR trimmer mower. It was amazing. This mower just hungered for my 5-6 foot high weeds and brambles. After 15 plus years of use it still is doing the impossible.
Direct Reduced Iron (DRI) (B) is a metallic material of a manufacturing process formed by the reduction (removal of oxygen) of iron oxide at temperatures below the fusion point of iron. Cold-moulded briquettes should be defined as those which have been moulded at a temperature of under 650oC or which have a density of less than 5.0 g/cm 3.
The Direct Reduced Iron (DRI) is usually used in its briquette form (Hot Briquetted Iron (HBI)) for easier transportation and it can be charged in the blast furnace (BF), inside the converters (BOF) and in the Electric Arc Furnace (EAF). The cycle of EAF is based on the metal scrap melting. The HBI manufacturing process involves the usage of a ...

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
ArcelorMittal Belgium will reduce CO2 emissions by 3.9 million tons per year by 2030, by building a 2.5 million-ton direct reduced iron (DRI) plant and two electric furnaces at its Gent site, to operate alongside its state-of-the-art blast furnace that is ready to take waste wood and plastics as a substitute for fossil carbon.. ArcelorMittal announces that it has signed a letter of intent with ...
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 coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

Because the direct reduction of iron is a solid-state process, the product DRI has roughly the same size and shape as the starting particles, whether roughly spherical pellets or irregularly shaped lumps. Due to process kinetics and the overall economics of direct reduction, very few DRI particles actually approach metallization ...

MIDREX is an innovative ironmaking process that has been specifically developed to produce direct-reduced iron from iron ores and natural gas/hydrogen. MIDREX is a gas-based shaft furnace process that converts iron oxides - in the form of pellets or lump ore - into direct-reduced iron (DRI). MIDREX technology is highly customizable, which means ...
It is due to produce about 100,000 tonnes per year of DRI. Initially the hydrogen used will be made from natural gas, but it is envisaged that some – or potentially all – of the hydrogen needed will be generated by equipment powered by renewable energy sources, once it is available in sufficient quantities and at a commercially viable cost.
