What is Sponge Iron? (with pictures) - Info Bloom
In addition, the gases emitted during the production of sponge iron can be harvested and used in various other applications. This by-product of the iron making process helps to offset the cost of producing the iron, as well as aid in keeping other processes that require the gas for proper production.

Direct reduced iron (DRI), also called sponge iron,[1] is produced from the direct reductionof iron ore (in the form of lumps, pellets, or fines) to iron by ...
Sponge Iron - Sambhv Steel
Sponge Iron. 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 ...
The Application and Benefits of Sponge Iron - PK Steel
Sponge iron is a metallic product produced through the direct reduction of iron ore in the strong state. It is a substitute for scrap and therefore is mostly applicable in making steel through the secondary route. The procedure of sponge iron making aims to expel the oxygen from iron ore. The level of metallization (expulsion […]
What is the completed Midrex process for sponge iron making?
Answer: Midrex Process for Direct Reduction of Iron Ore Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting...
SPONGE IRON PLANT
sponge iron, originating from Iron Ore, namely, silica and alumina and the sulphur and phosphorous contents adversely affect the economics in subsequent steel making operation. Therefore, the ore should be high in iron content and low in gangue, Physical Specification – Size - 5-20 mm Oversize - < 5 % max
Extractive Metallurgy: Sponge Iron Making
Sponge Iron Making The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. ...
Energy survey of the coal based sponge iron industry ...
Sponge iron is a metallic mass with honeycomb structure. It is produced by direct reduction of iron ore in the presence of coal and air. Since last few years, sponge iron has emerged as an alternate raw material for steel making. The Indian Government has recognized sponge iron as a vital sector for growth of Indian steel industries.
OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION …
1. Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge ...

Direct reduced iron - Wikipedia
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 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 ...
sponge iron process
We are the largest producer of sponge iron using non coking coal as a reductant and and are having the largest coal based plant in the world. We shall discuss in detail all technical aspects of coal base sponge iron making with particular reference to control of important process parameters to achieve quality sponge iron in this august gathering.
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 ...
