Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF rout In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction
the sponge iron The reduction process consists of two procedures, which are primary reduction (solid carbon reduction) and secondary reduction The primary procedure mainly includes: (iron ore, rolled steel scales, etc) → Drying → Magnetic Separation → Crushing → Sieving → Canning → Entering Primary Reduction Furnace → Sponge Iron

What is Sponge Iron? Sponge Iron is formally called Direct Reduced Iron and is produced by way of the direct reducing of iron ore India is the global leader of sponge iron ,
Since DRI is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting por These pores results in a large internal surface area which is about 10,000 times greater than the internal surface area of solid iron Due to it the DRI is also known as sponge iron
The company has the world's largest coal-based sponge iron manufacturing facility at Raigarh, Chhattisgarhand stands out as the market leader in coal-based sponge iron industry within India Efficient backward integration has rendered it as the only sponge iron manufacturer in the country, with its own captive raw material resources and power .
Jul 29, 2010· The size distribution of sponge iron lumps varies with decrepitating behavior of iron or As the Fe metallic content in sponge iron varies for each size fraction control of feed size of iron ore is very important for achieving uniform Fe metallic content The typical size distribution and Fe metallic for each fraction is as given below
A Choudhury 42 2 Description of Sponge Iron Manufacturing Process Most of the plants in India use DRI process—a solid state direct reduction process by which iron ore is reduced
Dec 25, 2016· Sponge iron is produced through direct reduction of iron ore in the solid state It is a substitute for scrap and is mainly used in making steel through the secondary route The process of sponge iron making aims to remove the oxygen from iron oreSponge iron is not useful by itself, but can be processed to create wrought iron
Sponge iron, or Direct Reduced Iron (DRI), is a process of extracting iron from its raw ore The process involves using gas, coal or dynamite to separate elements and remove impurities, which is .
→ Sponge Iron The secondary procedure includes: Sponge Iron→ Brushing → Magnetic Separation → Entering Secondary reduction furnace → becoming powder lump → crushing → magnetic separation → sieving → classifying → mixing →packing→finished iron powder product
A soldering iron stand keeps the iron away from flammable materials, and often also comes with a cellulose sponge and flux pot for cleaning the tip Some soldering irons for continuous and professional use come as part of a soldering station, which allows the exact temperature of the tip to be adjusted, kept constant, and sometimes displayed
Sponge Iron definition, categories, type and other relevant information provided by All Acronyms SI stands for Sponge Iron
Sponge iron Sponge iron, also called direct reduced iron, is the product created when iron ore is reduced to metallic iron, usually with some kind of carbon (charcoal, etc), at temperatures below the melting point of iron
It's not hard to season a cast iron skillet Here's how to do it and how to know when it's time to do it again , Wash the skillet: Wash the skillet with warm, soapy water and a sponge or stiff brush Cast iron should not normally be washed with soap, but it's fine here since the pan is about to be seasoned Rinse and dry: .
Pig iron is denser as it is a molten product While sponge iron has a lot of pores in it, that’s why you call it a sponge iron No doubt that both are iron, but the reduction process is different for each and so is the density of the product
Now a days,sponge iron is a name in steel making processThere are different methods to manufacture sponge iron but in India largely coal based process are carried outIn this process .
Iron sponge consists of hydrated iron oxide impregnated onto redwood ships The main drawback of this system is that during media changeout, the unreacted iron oxide can react exothermically with the air and catch fire
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams This process is applied to gases with low H2S concentrations (300 ppm) operating at low to moderate pressures (50-500 psig) Carbon dioxide is not removed by this process
We quote from the book Sponge Iron Industries  More pictures iron factories (page 5) “India is the largest producer in the world of sponge iron, a product derived from iron and used to make steel
Sponge iron can also be used to produce a powdered ore that works very well when mixed with other metals in the production of different types of iron-based products One of the more common uses .
