Sponge Iron, also known as Direct Reduced Iron is the product produced out of using iron ore. The iron ore is processed through reduction process by the use of gas that emits from natural coal gas resource. CASE Group of Industries manufactures sponge iron by using tunnel kiln, following reduction of iron ore through Static Kiln Briquetted Iron.
Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed in Tunnel kiln being stationary, it does not require high.

Sponge Iron Production From Ore Coal. In the year 1908 use of tunnel kiln started for iron oxide reduction This process was invented by ESieurin as Hoganas process 3 In 1954 more kilns came in operation in SWEDEN and USA Presently it is more popular in China for sponge iron production from beneficiated iron ore fines cakes In this process the material passes through.
Tunnel Kiln. Ceramic Tunnel Kiln Project We are supplier and manufacturer of Tunnel Kiln, Kilns for large volume production of Tableware, Pottery, Sanitary-ware, Refractories and Technical Ceramics. Regardless of the product to be fired we offer a complete range of tunnel kilns.
Lumps in total iron ore production has been about 40 with the rest being accounted for fines and concentrates. Iron Ore Finesblue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed. Moreover, the excessive fines generated from the iron ore crushing units are mostly stored as waste.
Steel Technology Roadmap 1Chapter 2 Ironmaking 2.0 Ironmaking Ironmaking involves the separation of iron from iron ore. Ironmaking is not only the first step in steelmaking but also the most capital and energyintensive process in the production of steel. There are three basic.
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. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore.
The Technology . Iron Ore Fines and Coal Fines mixed together are loaded into SiC Silicon Carbide beakers which are then loaded onto the cars. The cars are made to pass through the Tunnel kiln. The material goes through a series of Chemical Changes owing to the temeperature and pressures of the kiln.
Iron ore and non-coking coal are the prime raw materials for the production of sponge iron. These are charged into a rotary kiln in requisite proportion along with some dolomite. Coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at 950-1050 o C.
Production of Sponge Iron through Tunnel Kiln Process. April 2010 the quality of which is directly related to quality of iron ore. Ladle metallurgy is very important technology when it comes.
In place of sized graded iron ore, tunnel kiln process uses iron ore fines, and Request Quotation The technical force of our company is strong, has a number of invention and proprietary technology of tunnel kiln of direct reduction sponge iron.
This is the Latest Technology to Produce the Pig Iron or MS Iron out of the Iron Ore Fines and Non-coking Coal. In this Technology, the Coal Consumption is the minimal as compared to the Tunnel Kiln Process or Rotary Kiln Process. Through RHF, either Pig Iron Fe96-97 C3.0-4.0 or MS Steel Fe99 C0.2 Mn0.3 etc or HBI Hot Briquetted.
Mar 09, 2013018332The sintering technology was originally developed for the purpose of utilizing in the blast furnace the iron ore fines and the iron present in the metallurgical waste of a steel plant. But currently the focus has changed. Now the sintering process aims to.
CASE gave this technology to India and this was also first of its kind in India. The process has been established now after earlier hiccups. The process of Tunnel Kiln uses fines of Iron ore and Coal which are mixed together in specified propotions to eventually make DRI.
Iron OreTaconite In the ironmaking process, the blast furnace or direct-reduced iron DRI plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln.
The process of Tunnel Kiln uses fines of Iron ore and Coal which are mixed together in specified propotions to eventually make DRI having quality grades of 90 plus metallization The Technology Iron Ore Fines and Coal Fines mixed together are loaded into SiC Silicon Carbide beakers which are then loaded onto the cars.
We offer iron ore pelletisation plants from a reputed manufacturer in China, based on the grate kiln technology. The plants are available in capacities from 1,00,000 tons to 1,20,000 tons per annum.
However, in the world, almost 80 of sponge iron is being produced by the gas-based DR process. Both the gas and coal based DRI technology are gaining importance due to comparatively less investment cost, flexibility in using raw materials like cheap iron ore fines, non-coking coal and natural gas.
In order to explore the efficacy of iron orecoal composite pellets over ordinary green pellets, indurated pellets, briquettes as well as standard charging of material in the form of concentric layers of iron ore and coal fines, or their mixture, these pellets were tested at 1,150 176C in a 7 tons per day 7 tpd pilot tunnel kiln.
Coal Based Rotary Kiln for Direct Reduced Iron Sponge Iron 100 TPD, 350 TPD, 500 TPD Solid state reduction of Iron Ore using either coalgas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron DRI.
The iron ore fines cannot be directly As a new kind of ironmaking raw material, iron coke and carbon reduced iron in a rotary kiln and induration of wet iron ore pellets on a moving packed.
