3 sponge iron process as the name implies, the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. the iron content of the product so obtained varies from 90 to 94 and the balance represents the traces of gangue and residual iron oxide.
A process and an arrangement for the production of steel from sponge iron. in order to be able to process sponge iron with high contents of acid gangue andhosphorus content of more thann an economic and operationally safe manner, the following measures are taken melting the sponge iron charge, if desired, together with scrap, in an acidlined electric furnace,.

Description application shipment storage risk factors. directreduced iron dri, also called sponge iron, is produced from direct reduction of iron ore in the form of lumps, pellets or fines byeducing gas produced from natural gas or coal.the reducing gas isixture majority of hydrogen h2 and carbon monoxide co which acts as reducing agent.
Direct reduction is an iron making process for the new era, which utilizes natural gas to reduce iron ore to produce direct reduced iron dri. articles production of sponge iron through tunnel kiln process.
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 8001200 c. iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
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.
In the year 1908 use of tunnel kiln started for iron oxide reduction. this process was invented by e.sieurin 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.
Inr process, iron ore pellets andor lump iron ores are reduced byeducing gas to produce dri or hot briquetted iron hbi. depending on the generation of the reducing gas, two different dr processes are commercially available gasbased and coaloilbased. the sponge iron dri produced as solid end product is melted in electric arc.
Inuge container calledlast furnace. iron ores such as haematite contain ironiii oxide, fe 3.the oxygen must be removed from the ironiii oxide in order to leave the iron behind.
Iron is mainly produced through two methods the blast furnace, bf, route pig iron, and the direct reduction, dr, route sponge iron. according to the world steel association, 2011 crude steel production was standing at 1.4 billion tonnes by the end of 2010.
Iron ore consists of oxygen and iron atoms bonded together into molecules. to create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. to purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. to coax the oxygen atoms away from the ore requires.
