There are many different resources involved in the construction of a building but the most important resource is the reinforced steel bar. The types of reinforced steel bar grades are Fe 415, Fe 500, Fe 550, Fe 600. The manufacture of steel begins with the steel making process, in which pig iron is purified and alloyed to make ingots.
In addition to blast furnace (BF) process in iron and steel production Corex, Romelt, Midrex, Hyl-3 processes are used currently. Pig iron or sponge iron with scrap iron addition are loaded into electric arc furnaces (EAF) for steelmaking [1-4]. There is a problem of comparative assessment of carbon dioxide through emission (carbon
PDF | COREX process for pig iron production is a commercially proven process, and is currently considered as the main competent to blast furnace for pig iron production. COREX process consists of ...
The Corex process, 24 commercialized by Voest Alpine, combines an iron melter/coal gasifier vessel with a pre-reduction shaft to produce a liquid product that is very similar to blast furnace hot metal. Coal, oxygen, and pre-reduced iron are fed into the melter/gasifier to melt the iron and produce a highly reducing off-gas.
Given that background, the article confuses the readership with the term Pig Iron Pellet to refer to COREX (process (5) above) iron ore pellet charge used by HISARNA's predecessor plant at Corus, with perhaps a solid sponge iron product of say SLRN (process (1) above), or the powdered iron product of ITmk3 (process (2) above), or the hot ...

Corex process captures most of the pollutants in an inert state in the slag and the released hydrocarbons are destroyed in the dome of the melter-gasifier. The challenge Economical iron making basis for a new steelworks in an isolated area with limited access to fuel gas.
In the past twelve months, Siemens VAI has been the first company to utilize new technologies which make an active contribution to protection of the climate in full scale production sites: the Corex and Finex methods for the production of pig iron and Meros for the treatment of waste gases from the sinter process.
The plant rated capacity is ranging fromtons per year totons per year. After being reduced, the DRI is redirected to the char proceds where the iron and slag are melted and then directed to the hearth zone. Corex Process. Meanwhile, in a two-stage process, like Corex, the ore is reduced in one shaft and melted and purified in another.
Experience of COREX at JSW suggest that still ~ 15% coke is required in the process to control VM of the input reductant. Same may be the case for FINEX process. Use of pellet atleast partially is a must for COREX process . For FINEX & HISMELT process, iron ore fines can be directly used.

Well that is a lengthy one from refinement of ore of its impurities to pig iron, blast furnace is one commonly used an alternative eco-friendly process - Corex process is used. JSW Steel claims to be the first Indian company to adopt the corex pro...
The main product, the hot metal can be further treated in either EAF or BOF or can be cast and sold as pig iron (US DOE, 2003). A modified version of the Corex process enables the recycling of off-gases back to the process and thereby reduces the energy consumption of the process further.
· Pig Iron. Pig iron is the basic material from which, wrought iron and steels are produced. It is obtained by smelting (chemical reduction) of iron ore in the blast furnace. In addition to iron, Pig iron contains varying quantities of other elements such as carbon, …
Blast furnace iron making is the main method for modern steel production,the process of blast furnace is an important part.
The Corex process reduced sulfur and nitrogen oxide emissions as well as ultrafine dust particles in exhaust gases, by as much as 90 percent compared to conventional pig iron processes. And the export gas from the Corex plant was used to generate electricity in a combined-cycle power plant, and to heat the entire Baosteel mill.
Production of Pig Iron by Using the Romelt Process . In the iron and steel industry in the world there are currently two types of factories that produce ferrous metals. There are so-called integrated plants, which start from the extraction of iron ore from the mine to the final rolled products.
Pig iron production used akome iron sand (with high titanium content, as 5% or more of TiO 2) which was added after the charcoal charge; ... The COREX process is a two-stage process, as is shown in Figure 1.1.40. In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced ...
Reduction Process direct reduced iron (DRI)/hot briquetted iron (HBI)/EAF routes to the new innovative Alternative Iron Sources (AISs)/steelmaking routes such as the FASTMET Process, the ITmk3 process, FASTEEL, FASTOx, COREX and HIsmelt. Definitions of the process …
