Sponge Iron CompositionManufacturing Process . Process. Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled with a ‘select’ grade of iron-coking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise inExtractive Metallurgy: Sponge Iron Making,Sponge Iron Making The process of sponge iron manufacturing involves removal of oxygen from iron ore.,Iron and Boudouard reaction Diagram . After processed in rotary kiln, the product sponge iron come to the water cooled cooler where its temperature reaches to 80 to 100°C.Direct reduced iron - Wikipedia,Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes,

Therefore, the ore should be high in iron content and low in gangue, Physical Specification – Size - 5-20 mm Oversize - < 5 % max

Sponge Iron - an overview | ScienceDirect Topics

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. The reduction takes place using gaseous reductants (CO + H,SPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE,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.

Sri Subramanya Sponge Iron Pvt. Ltd., (SSSIPL), in the year 2007. They had installed 1 x 75 Tons per Day (TPD) Sponge Iron Plant, to produce the sponge iron from iron ore lumps and pellets, to cater to the growing demand for sponge iron in Bellary-Hospet

Ironmaking 101 – From Ore to Iron with Blast Furnaces,

Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.Sulphur removal in ironmaking and oxygen steelmaking,BF-BOF steelmaking process comes from coke. Even though roughly 40% of the sulphur in coal is removed in the coking process, typical sulphur levels in coke remain around 0.5%. Iron ore contains typically 0.01% sulphur and is only a minor source of sulphur in the steelmaking process [2,8]. In the BF-BOF process there are four process steps whereSPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE,In the year 1908 use of tunnel kiln started for iron oxide reduction.
