DRI (direct reduced iron) or another name as sponge iron, is a kind of mid product in the steel making process. It gained great prominence as a substitute for the metal scrap (steel) in the furnace. The briquette machine for DRI normally has two types – hydraulic type and hydraulic roller type .
DRI based steel making is therefore the only answer. Sponge iron, also called Direct-reduced iron (DRI), 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

In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based.

direct reduced iron (DRI): Alternative iron source produced by heating an iron ore (generally having 65 to 70 percent iron) at a temperature high enough to burn off its carbon and oxygen content (a process called reduction) but below iron''s melting point(1535°C or 2795°F). The output is sold as pellets or briquettes (called hot briquetted iron
Direct iron reduction processes produce a form of sponge iron called direct reduced iron (DRI). Smelting reduction and direct iron reduction can reduce energy input, lower greenhouse gas emissions and minimize slag byproduct generation, resulting in overall cost, productivity and life cycle enhancements.
11/8/2020· Increased scrutiny over greenhouse gas emissions in iron and steel production have prompted all parties involved in its value chain to invest significant resources into reducing their carbon footprint. ROBERT HOBSON reports.
Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, 500 TPD) Solid state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI).
