Sponge iron is produced through direct reduction of iron ore in the solid state. Sponge iron is an iron source relatively uniform in composition, and virtually free from tramp elements. It is mainly used in Electric Arc and Induction furnaces to dilute the contaminants present in the scrap.

Sponge Iron and ItIron For I:led:ric Furnace, of the sponge iron reduction furnace, the resulting cost of the sponge iron, and the cost of removing the residual oxide in the steel furnace While sponge

Sponge iron is rich in Metallic Iron (Pure Iron) with consistent chemical physical characteristics. This provides steel makers flexibility in preparing their furnace charge to produce finer quality steels than what is possible using steel scrap only.

Iron making (Mini Blast Furnace, Sponge Iron Plant, Sinter plant). Steel Making (Electric Arc Furnace, Ladle Refining Furnace (2Units), Vacuum Degassing, Argon Oxygen Decarburization). Casting (Continuous Casting Ingot Casting).

Large scale iron ore smelting has been carried out in numerous types of blast furnaces since the industrial revolution, with the basic ingredients of coke, iron ore and limestone remaining unchanged, being loaded into the blast furnace from where the molten iron is tapped into molds.

Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore.

The sponge iron plants can also be set up quite rapidly and it now takes just 18 months to go on stream for a major plant. . the furnace (rotary kiln) . DESIGN OF WASTE HEAT RECOVERY SYSTEM IN A SPONGE IRON PLANT

India, the world's largest producer of sponge iron 23 MMT, expected to maintain its lead in the near future. Sponge iron production grew at a CAGR of 11 per cent to reach a level of million tonne in 200809 compared to million tonne in 200405.

Smelting will also pause if one leaves the dimension the furnace is located in. If the player sleeps in a bed while a furnace is smelting items, the furnace's progress will be the same as if the bed had not been used and no additional time had passed.

Unlike steel scrap, iron scrap, and pig iron, the sponge iron is characterized by (i) high porosity,(ii) low density, (iii) low thermal conductivity, (iv) high specific surface area, (v) high oxygen content, and (vi) intermediate carbon content. Sponge iron has uniform chemical and physical characteristics.

induction furnaces is steel scrap, cast iron and sponge iron. India is the only country where use of sponge iron contributes a large share in annual crude steel production. The amount of sponge iron in the charge mix varies from 0 to 90 % depending on its availability and economics of production.

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.

The source of both pig iron and sponge iron are iron ore. In case of pig iron, the ore is reduced and melt in the blast furnace and the preliminary product id liquid iron, which solidifies to pig iron. On the other hand, sponge iron is achieved by reduction of iron ore in a solid state process. The ore is never melted.

the sponge iron. The reduction process consists of two procedures, which are primary reduction (solid carbon reduction) and secondary reduction. The primary procedure mainly includes: (iron ore, rolled steel scales, etc.) → Drying → Magnetic Separation → Crushing → Sieving → Canning → Entering Primary Reduction Furnace → Sponge Iron.
