Sponge Iron - an overview ScienceDirect Topics

The process involves heating the naturally occurring iron oxide in the presence of carbon, which produces “ sponge iron.” In this process, the oxygen is removed without melting the ore. Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface ...

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) 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 ...

What is Sponge Iron? (with pictures) - Info Bloom

04/02/2021  Malcolm Tatum Date: February 04, 2021 Sponge iron is created from iron ore.. Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore.The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source.

Sour gas sweetening - PetroWiki

06/07/2015  Iron sponge (Iron Oxide) Iron sponge consists of wood chips that have been impregnated with a hydrated form of iron oxide. The material is placed in a pressure vessel through which the sour gas is flowed. Because this is a batch process, usually two vessels are installed—one in service and the other on standby. The H 2 S reacts with the iron oxide to form iron sulfide. In due course, the ...

Direct Reduced Iron and its Production Processes –

16/03/2013  Fig 2 Principle of direct reduction process. Gas based process. In the gas based reduction processes, a vertical shaft kiln is used in which iron ore is fed into the top of the kiln and finished sponge iron is drawn off from the bottom after cooling it so as to prevent its re-oxidation. The reducing gas is passed through the ore bed, and spent ...

Carburizing - Wikipedia

Carburising, carburizing (chiefly American English), or carburisation is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide.The intent is to make the metal harder.Depending on the amount of time and temperature, the affected area can vary in carbon content.

What is Sponge Iron? (with pictures) - Info Bloom

04/02/2021  There are several benefits associated with sponge iron that allow it to compete effectively with other types of smelted irons. One has to do with the actual composition of the final product itself. For example, this type of iron is considered

A Thesis Submitted for Partial Fulfillment of the Degree ...

following advantages sponge iron production is rising. Pelletized iron ore or natural "lump" ore are used in direct reduction process. Exceptionally in the fluidized bed process sized iron ore particles are used. Few selected ores are suitable for direct reduction process.

Carburizing - Wikipedia

The process is environmentally friendly (in comparison to gaseous or solid carburizing). It also provides an even treatment of components with complex geometry (the plasma can penetrate into holes and tight gaps), making it very flexible in terms of component treatment.

DESIGN OF WASTE HEAT RECOVERY SYSTEM IN A SPONGE IRON

process uses coking coal. The DRI process doesn‟t require coking coal and therefore is advantageous. In the present work waste heat recovery system is designed to integrate the heat of waste gas in the sponge iron process. For this purpose a case study of typical sponge iron production process is considered. The waste gas from a sponge iron plant exits at a temperature of around 200-300 C. A

10/09/2020  Design and Process Advantages. In the newly designed sponge iron rotary kiln system, a coarse coal branch pipe and fine coal branch pipe are added at the kiln head. The original way of adding 100% coal at the kiln head is changed to 50-70% coal is added together with fine iron ore and dolomite through the mixing mode at the kiln tail, and the remaining 30-50% coal is added by the kiln head. The

Direct Reduced Iron Industry in India — Problems and Prospects

`the quality requirements for the rotary kiln sponge iron process. The sponge iron fines generation is high and ranges from 15 — 30% depending upon the ore used due to high reduction degradation. This will not only reduce the sales realization of the product but also will lead to accretion formation in the kiln shortening the campaign life. Many plants are using pebbles for this reason which will help to a

Direct Reduced Iron (DRI) Production Plant NIPPON STEEL ENGINEERING CO., LTD. Basic Concept or Summary S-16 u A direct reduced iron (DRI) production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases. u While the produced DRI is mainly used as the raw material of electric steelmaking,

Coal based Direct Reduction Rotary Kiln Process – IspatGuru

The process has the advantage of low capital expenditure and no requirement of coking coal. The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct

Difference Between Sponge Iron and Pig Iron Compare

30/04/2011  Furthermore, we can produce sponge iron from many types of furnaces such as blast furnace, charcoal ovens and oxygen furnaces. Sponge iron has many advantages over other similarly smelted iron forms. Sponge iron is superior to pig iron as it is richer in iron content. Because of this property, it has many uses in electric furnaces. We can mix sponge iron, in its powdered form with many other metals to manufacture a variety of iron
