sponge iron and or pig iron is also used for chemical balance. In basic furnaces slag formers like limestone, fluorspar, sand, and quartzite are used to form a slag to refine the metal. For decarburization oxygen lancing is used. Iron ore is also added. Ferromanganese, ferrosilicon or al uminium are used for deoxidation. To produce alloy ...
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or ores are suitable for direct reduction. Direct reduction refers to solidstate processes which reduce iron oxides to metallic iron at temperatures below the melting ...
Sponge iron is a metallic product obtained by reduction of iron oxide in solid state, which is used for manufacturing steel. Steel is manufactured from iron ore mostly using blast furnace (BF) and basic oxygen furnace (BOF) and using electric arc furnace (EAF) in case of manufactured from scrap materials. Molten iron is produced in BF in presence
Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, and 500 TPD) Solidstate reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of connecting pores ...
· The iron feed to an Inmetco furnace is in the form of disk pellets made of fine iron ore under 250 micro meters in size and fine coal or coke or char with less than 25 % volatile matter. They are distributed onto the RHF in a layer which is around 3 pellets deep by means of a pivoting belt conveyor. The process uses a quick acting binder which allows the pellets to be transported to the hearth ...
Sponge iron induction furnace. The sponge iron used in induction furnace should have a high metallization. This will result in a high melting efficiency. In fact, there is no possibility of using second grade sponge iron in the induction furnace due to the structure of these furnaces. While the electric arc furnace type are less sensitive to induction. Sponge iron carbon percentage. Sponge ...
· A sponge iron has indistinguishable iron content from the pig iron; therefore it is an excellent feedstock for the electric furnaces utilized by smaller factories. It enables them to use lower grades of scrap for whatever remains of the charge or to create higher grades of steel. Appliions Of Sponge Iron. Sponge iron has a wide number of ...

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 prime raw material for induction furnace is steel scrap, sponge iron and cast iron. The percentage of directly reduced iron in the burden differs from 10 to 95 percent, depending on its inventory and monetary value of manufacturing. Large scale of steel formed through secondary route is alloy steel and plain carbon steel. [2] In the present work, our objective is to set up preliminary info ...
Blast furnace: This kind of furnace is used primarily to extract iron from its ore. But it can also be used for extracting gold from iron ore plant. This means that once the iron has been extracted through blasting, gold will become part of the remnants or remaining materials. The usual dimensions of the blast furnace can be anywhere from 60 meters tall to 15 meters in diameter. This furnace ...
draft finalized by the Sponge Iron Sectional Committee had been approved by the Metallurgical Engineering Division Council. During the past few years the use of sponge iron has become increasingly important, in the electric arc and other steel making furnaces mainly due to irregularity in price and the poor quality of scrap available. Also, due to its inherent plus points like nature ...
