The important amongst them are COREX, Direct Iron Ore Smelting Process (DIOS), Hi Smelt Process etC, NML has developed a process using non coking coal as reductant to produce sponge iron in a vertical retort direct reduction furnace developed at NML And the sponge iron so produced is

(1) The experience of melting sponge iron in induction furnaces infers that the best usage and melting of the sponge iron can be achieved if the particle size of the sponge iron is in close range and its metallization is + 90%. The density of its particle should be as high as possible. (2) Even acidic slag facilitiates the melting of sponge iron.

Of the total domestic consumption of iron ore, about 98% accounts for pig iron and sponge iron industries. sponge iron also referred to as Direct reduced iron (DRI), based both on coal and gas as well as to produce .. Process Technology: A simplified flow diagram of sponge .

Ironprocess iron making process YouTube. Sep 29, 2012 · Sponge iron is not useful by itself, but can be processed to create wrought iron. The sponge is removed from the furnace, called a bloomery, and repeatedly beaten with heavy hammers and folded over to remove the slag, oxidise any carbon or carbide and weld the iron together.

Unlike the Kroll process that tends to form sponge high in iron near the reactor walls, sponge throughout the Hunter reactors is of uniform grade and low in iron content. The 1974 NMAB report alluded to the desirability of doing the second stage, as well as the first stage, of the Hunter reaction in a continuous manner as was investigated by ...

Sponge Iron Production From OreCoal Composite . Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution.

Carbon mitigation using biomass gasification to displace natural gas, during sponge iron powder production ... The next few pages the sponge iron process at Höganäs, that is used to produce iron powder, ... Inside each retort, there is a tube formed sponge iron cake with a porosity of about 75%, and residue of unburned coke breeze blended ...

For those who don't know, the bloomery process (also referred to as direct reduction) is the original method of producing iron. Operating on a small scale and at relatively low temperatures, it produced a sponge of malleable iron and slag that was forged directly into a wrought iron bar or billet.

We manufacture Centrifugal Castings via Horizontal Vertical Process. Ranging in size from 50 mm up to 1200 mm OD up to meters long, typical minimum wall thickness of 6mm. Pipe and tubes made by Centrifugal Casting and Welding, enables us to provide pipes and tubes 7 meters in length with weld joint.

Related manufacture(s) Description of manufacturing process M1: Iron Powders (Iron Powder made by sponge iron process, atomization processes (gas and water) and electrolysis)

Natural gas is reformed to enrich with 112 and Co mixture and this enriched and reformed gas mixture is preheated in gasbased process. A vertical retort is used for the reduction of iron ore as against a rotary kiln in coal based sponge iron process. When the gases are traveling upwards the charge moves downward by gravity.

The process of DRI or sponge Iron making can be classified into different categories, which are as follows. Rotary Kiln Processes Rotary Kiln Processes are very useful for Sponge Iron Production using noncoking ... In Retort process the reactor vessel is a retort where the charge is fed from top end

In this process, heat was supplied through the direct electricalresistance heating of the coke in the charge. The most serious disadvantage of the improved retort processes was that they were restricted to ore concentrates with a low iron content, because high iron content in the feed caused plates of iron to form in the retorts.
