Rotary Kiln Process of Making Sponge Iron C. Rotary Kiln Process of Making Sponge Iron HISTORICAL BACKGROUND The production of steel began in ancient times; but because of the complexity and slow. iron ore pellets are mixed and stone bandsealer. sponge iron. the process of sponge iron making aims to remove the oxygen from iron .
The size distribution of sponge iron lumps varies with decrepitating behavior of iron ores. 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.
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.
KOLKATA: Sponge iron and pellet manufacturers in Odisha are reeling under a severe shortage of iron ore fines, because their mining leases haven't been renewed. The short supply has also driven up the price of the key raw material for these companies.
Pellets, Bahrain Steel has secured its highquality iron ore requirements for its plants from the most reliable and reputable iron ore suppliers through longterm (up to 25 years) contracts. Bahrain Steel's major suppliers include the following suppliers: Anglo American PLC, Brazil Companhia Siderurgica Nacional (CSN), Brazil.
Oct 20, 2018· Sometimes known as directreduced iron, sponge iron is a product that is produced using iron ore. The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source.

Sponge iron is the product created when iron ore is reduced to metallic iron, in the presence of coal, at temperatures below the melting point of iron. The external shape of the ore is retained with 30% reduction in weight due to oxide reduction resulting in change in .
Advantages of Pellets: Pellets are uniformely sized, with purity of 63% 68% contributing to faster reduction and high metallization rates. Pellets with their high, uniform mechanical strength and high abrasive strength increase production of sponge iron by 25% to 30% with same amount of fuel.
In order to explore the efficacy of iron orecoal composite pellets over indurated iron ore pellets, standard charging of concentric layers of separate iron ore, coal fines, or their mixture, these pellets were tested at 1200oC in the tunnel kiln.
Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 816 mm in diameter .
