DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet andor lumpy form.
The Sponge Iron Manufacturers Association SIMA established in 1992 is an all India apex body of Indian sponge iron industry.

As a not-for-profit society, SIMA has been mandated to communicate the viewpoints of its constituents amp al ...
The ability to regulate oxygen consumption evolved in ancestral animals and is intrinsically linked to iron metabolism. The iron pathways have been intensively studied in mammals, whereas data on distant invertebrates are limited. Sea sponges represent the oldest animal phylum and have unique struct
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 8001200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants CO H ...

Jun 21, 2021 SSAB, LKAB and Vattenfall AB have now produced the worlds first hydrogen-reduced sponge iron at a pilot scale. The technological breakthrough in the HYBRIT initiative captures around 90 of emissions in conjunction with steelmaking and is a decisive step on the road to fossil-free steel.
Sponge Iron can be utilized as a substitute for steel scrap. It plays a pivotal role as feed material in all mini steel plants. Sponge Iron is an apt material as it can be utilized as a coolant in Integrated Steel Plants. Sponge Iron is manufactured by reducing iron ore without the melting process thereby making it energy efficient. The ...
A method for manufacturing sponge iron includes heating iron oxide together with a solid reducing agent to reduce the iron oxide into sponge iron, wherein the iron oxide includes a mixture of powdered hematite and powdered iron ore or a mixture of powdered hematite and powdered mill scale, the powdered hematite has a specific surface area of 2.0 m 2 g or more, and the content of the powdered ...

Mar 16, 2013 In the gas based reduction processes, a vertical shaft kiln is used in which iron ore is fed into the top of the kiln and finished sponge iron is drawn off from the bottom after cooling it so as to prevent its re-oxidation.
The Midrex and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Finmet Finored gas-based process utilizes iron ore fines as feedstock. The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.

For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI HBI In this process route, iron oxides are converted to the DRI HBI by using natural gas in a vertical shaft furnace. For steel producers, it is a preferred metallic, energy efficient and much more eco-friendly route.
