following advantages sponge iron production is rising. Pelletized iron ore or natural "lump" ore are used in direct reduction process. Exceptionally in the fluidized bed process sized iron ore particles are used. Few selected ores are suitable for direct reduction process. Sponge iron is produced in a powdered form so, it acts as a good raw material that can very well mixed with other metals ...
SPONGE IRON PRODUCTION FROM ORE COAL COMPOSITE PELLETS IN TUNNEL KILN . 1*, G. G. Roy2 1 Project Engineering Consultancy, Keonjhar, Odisha, India 2 . Indian Institute of Technology, Kharagpur – 721302, India. Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. .
Sponge iron production process requires accurate monitoring and control of the process parameters. The performance of rotary kiln sponge iron based processes is normally affected by accretion build up along the kiln linings. Accretion build up is the accumulation of semimolten material which form rings along kiln lining. These rings narrow the kiln diameter thereby hindering efficient ...

· In the coalbased DR process, reducing gas is produced from noncoking coal in the reduction zone of the furnace, typically a rotary kiln. (Sponge Iron Plants) Typical examples of coalbased process include SL/RN and ACCAR processes. Such coalbased sponge iron making from iron ore is popular both in India and China. However, in the world, almost 80% of sponge iron is being produced .
Sponge Iron Production Process Process description This is the case study of typical coal based sponge iron plant of 500 tonne per day capacity. The process flow diagram (PFD) of the sponge iron process is shown in Fig. 1. Different streams in the PFD are .
Primus Process For Sponge Iron Production quoraindia is the worlds largest producer of sponge iron, most of which is produced primarily through the coal based method of production growth in the sponge iron production can be attributed largely to the popularity of secondary steelmaking route,.Direct reduced iron wikipediadirectreduced ironget priceSPONGE IRON PLANT,The major .
· Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gasbased shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas. The principle of the reduction process using reducing gas is shown in Fig 1. Fig 1 Principle of ...
`the quality requirements for the rotary kiln sponge iron process. The sponge iron fines generation is high and ranges from 15 — 30% depending upon the ore used due to high reduction degradation. This will not only reduce the sales realization of the product but also will lead to accretion formation in the kiln shortening the campaign life. Many plants are using pebbles for this reason which ...
in sponge iron Fines — It refers to cold sponge iron fines with size 03mm obtained during production of sponge iron through solidlgaseous reduction route. Binders — They refer to additives used in the briquetting process for increasing the strength of the briquette and as lubricants to decrease the roll wear.

1. Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and desulphurizing agents (limestone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge ...
Explain manufacturing process of sponge iron . Sponge iron production is very sensitive to the characteristics of raw materials. Therefore, it is very important to study the chemical and physical properties of raw materials separately in the composition. Raw materials for the production of sponge iron include iron ore, noncoal, and dolomite. For direct iron ore regeneration, the main kiln ...
Process for production of sponge iron by direct reduction of iron ore wherein iron ore admixed with a carbonaceous reducing agent is passed through a rotary kiln countercurrent to a gas stream, and wherein granular coking high volatile coal is injected cocurrent to said gas stream as a solid reducing agent by means of oxygen containing gases through an inlet pipe, and said solid reducing ...
Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non coking coal as the fuel and reducing agent in Rotary Kiln. Sponge iron is rich in Metallic Iron (Pure Iron) with consistent chemical physical characteristics. This provides steel makers flexibility in preparing their furnace charge ...
The relates coalbase direct reduction process for sponge iron with different shape by tunnel kiln without outer combustion chamber and the combination comprises as shown in abstract figure: to iron concentrate, firing pellet, cooling or compacting; preparing the reducer; blending, loading into retort; entering the kiln; out the kiln; and sorting.

· Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using noncoking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes. The reducing agents are carbon monoxide (CO) and hydrogen (H2 ...
