DRI production. In the DRI plant, iron ore in the form of DR pellets 8 Production of DR pellets is not entirely carbon neutral due to natural gas or oil residues used in baking. is reduced with hydrogen in order to form DRI. 9 Hydrogen with a purity of > percent needed as a reduction agent in the DRI.
Direct reduced iron ( DRI ), also called sponge iron, [1] 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.

• DRI is a high Fe, low residual metallic material for producing high quality iron and steel products in a wide variety of furnaces • DRI is shipped as old DRI, but in integrated DRI/EAF mills can be charged hot directly to the EAF (furnace discharge temperature is 650700°) The valueinuse of DRI is different for each melt shop and will ...
Iron ore, coking coal, scrap, DRI/HBI and merchant pig iron trade data by major country. Monthly price forecasts for MBR's major steel raw materials benchmarks. Future 3 month prices, open interest and trade volumes for iron ore, coking coal, coke, wire rod and HRC.
It is also the world's thirdlargest producer of LNG and is forecast to be the world leader by 2020. Reduction of iron ore to reduced iron form adds value and provides more compact products, which reduces shipping costs. The specific iron content of the direct reduced iron is a function of the iron content of the iron ore.
DRI: This iron production process directly reduces iron ore in solidstate with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gasbased DRI) or coal (coalbased DRI) called syngas, a mixture of H 2 and CO. Although DRI production is more energy efficient than pig iron production from BF ...

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 .
The shaft furnace direct reductionelectric arc furnace (DREAF) route (Fig. 1) is the primary alternative to the BFBOF route, which reduces lump ore/pellets to direct reduced iron (DRI) primarily using natural gas (NG), and further converts the DRI in an EAF. The DREAF route significantly reduced the consumption of coke and coal while ...

In Germany, the group already operates Europe's only DRIEAF plant in Hamburg, where the switch to using hydrogen instead of natural gas in the iron ore reduction process is being prepared. The objective is to reach industrial commercial maturity of the technology by 2025, initially producing 100,000 tonnes of sponge iron a year. Background
However, overseas DRI producers benefit from lower hydrogen costs, lower iron ore sourcing costs, potentially simplified supply chains, and lower shipping volumes. 7 Shipping volume assumes metric tons of iron ore per metric ton slab versus metric tons of HBI.
It was found in the literature that a tumble index above 92% and an abrasion index below 6% show quite good strength for iron ore pellets for the Midrex process [21]. For C 1 A1100 • C, the ...

The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the noncoking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
Traditionally, DRI is produced from the direct reduction of iron ore using natural gas, but emerging technology is enabling the production of DRI using hydrogen as well. Depending on the source of the hydrogen, this offers the potential for truly green steel.
