What Is Involved in Sponge Iron Production (with picture) 8 Dec 2014 Sponge iron production is a technique of purifying iron ore by reacting it with gas mixtures to remove oxygen via a reduction process. Iron ore.
The innovation added capacity in production will enable the company to use the entire production of Iron ore produced at the mines for manufacturing sponge iron and further production billets by end of 2016 by adopting the means of forward integration.
Sponge iron production. Sponge Iron is a processed iron ore prepared and manufactured for use in induction furnaces and arcs in several stages. As you know, direct use of granulated iron ore, which often has a purity range of 50 to 65 , or use of iron ore pellets having a purity of between 64 and 69 is unlikely for these types of furnaces.
Iron could be lowered to 3.5-3.7 kilo-caloriesIton of sponge iron with partial recirculation of char. The trials yielded adequate data for designing a commercial prototype, or for industrial production of sponge iron. Introduction The direct reduction - processes, developed for converting iron ore directly into metallic.
Products [1-2]. In the year 1908 use of tunnel kiln started for iron oxide reduction. This process was invented by E.Sieurin as Hoganas process . In 1954, kilns came in operation in SWEDEN and USA. Presently it is popular in China for sponge iron production from beneficiated iron ore.
Sponge iron is a highly processed form of iron ore that contains metallic iron in the range of 83-88 obtained by direct reduction through reaction with carbon in the form of coal at approx. 1100 degree Celsius. Due to high porosity, the resulting iron is called sponge iron. Sponge iron is also referred to as direct reduced iron or metalized iron.
Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of.
A laboratory study was carried out to explore the prospect of obtaining a high quality pelletizing concentrate suitable for sponge iron (SI) production by concentration of an iron ore rich in.
2 KILN BASED SPONGE IRON PRODUCTION PROCESS Rotary kilns are found in many processes that involve processing of solids. This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The.
184.108.40.206 Direct Reduced Iron. DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
Sponge Iron Units 18.50 29.60 Total 53.31 Note Assuming no scrap is being used. For producing one tonne of crude steel, 1.6 tonnes of iron ore consumption has been assumed. If we add iron ore requirements of RINL of about 5.00MT (3.13 MT x 1.6 tonnes), the total iron ore requirements from non-captive mines work out to 58.31MT or about 60MT. Out of the total.
Sponge iron production process discussed herein are selected from known methods of which the references are available and referable. We look at the 4 different methods of producing sponge iron Midrex process. HYL process (4th generation) or Energiron. SL RN process. Tunnel furnace process.
Grade iron ore and lack of economies of scale. Under the current backdrop we will analyze the industry dynamics, challenges and outlook. Production Trend Sponge Iron production in India witnessed a CAGR of 14.77 during the period 2004-05 to 2009-10. However, the growth rate was.
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 co-current to said gas stream as a solid reducing agent by means of oxygen containing gases through an inlet pipe, and said solid reducing.
In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.
Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. – 5.
Jul 28, 2017 The iron ore mining was banned in Karnataka (July 2011) and Goa (September 2012) because of environmental concerns, land use and other covenants. Consequently, the sponge iron production declined by ~23 between 2011-13. The price of sponge iron gained momentum during the period owing to demand-supply mismatch. The sponge iron prices increased.
Unlike pellets, which still contain oxygen and must be further processed by the customers, sponge iron is pure, ready-made iron. Today's iron ore pellets must be reduced to iron before being used in steelmaking. To do this, customers use our pellets either in a blast furnace or in a direst reduction plant for production of sponge iron, often.
Pellets are small balls of iron ore produced from the iron ore fines with a better tumbler index than the parent iron ore and are effectively used as a substitute for lump ore for the production of sponge iron and in a blast furnace for the production of hot metal.
Typically, the Integrated Steel Plants(ISPs) use medium High grade Iron Ore whereas the Sponge Iron plants require only High Grade iron ore, preferably, with +67 Fe . Lumpy Fine Ore Iron Ore is traded in lumps (i.e. sized ore) or in fines. Production availability of lumps is limited by virtue of the natural occurrence and also because of.
Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. See rmation about the production of DRI . Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF.
In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850 C -1,500 C).
