Direct Reduced Iron (DRI) - Cargo Handbook - the world's ...

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.

A leader in metal powders born in Sweden | Höganäs

The method means reducing iron ore with the help of coke, lime and clay. After patenting the method, Höganäs starts production in 1911 and in 1912 a plant is built. Later on, Höganäs will start grinding the reduced iron to powder, sponge iron powder. It is named after what the iron particles look like in a microscope: sponge. 1940-61

Analyses of Different Modifications Proposed for the ...

Abstract. In the present work, an effort is made for best utilization of waste heat to reduce energy requirements in sponge iron plants. For this purpose, based on the principles of process integration, three design modifications, scheme-1, scheme-2, and scheme-3, are proposed and applied on actual data of two sponge iron plants being operated in India.
