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 two reactors; the reduction shaft, and the melter-gasifier. The process involves multi-phase, multi-component, having about five raw materials, and three main products.
It is the process according to which most steel ( 60 % ) is produced worldwide. With the help of the LD process it is possible to economically process large quantities of pig iron and scrap and supply crude steel of special quality.. Other milestones were the establishment of a steel degassing plant, the construction of a 120 m rail flow adjusting plant and a plant for the heat treatment of ...
Corex is a smelting reduction process combining a melter gasifier with a reduction shaft. The process takes lump iron ore or pellets, non-coking coal, and oxygen as main inputs. Similar to the blast furnace process, the reduction gas moves in counter flow to the descending burden in the reduction shaft.
Jul 02, 2013· Corex Process for Production of Iron; Share This. ... HIsmelt process of Ironmaking ... process is liquid iron or hot metal which can be used in steel melting shop or cast in pig casting machine to produce pig iron. The byproduct of the process is slag and the off gas.
The COREX process offers high smelting intensity and hence higher productivity, ability to use various types of non-coking coals, use of iron ore fines to an extent, low net operating cost, possible generation of power or other alternative use of export gas generated from the ironmaking unit, besides being eco-friendly.
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 ...
One of the modern technologies of producing pig iron, connecting the processes of the reduction and smelting, already applied practically, is the COREX process, . The traditional technology "blast furnace — LD (Linz-Donawitz) Converter" now dominates in the production of steel all over the world.
Midrex is an innovative ironmaking process, developed for the production of direct-reduced iron (DRI) from iron ores and primarily natural gas. Midrex is a gas-based shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct reduced iron (DRI).
COREX ® /MXCOL ® Option; Hot Transport Systems ... ITmk3 ® is an ideal way for iron ore mining companies to process either magnetite or hematite and supply a premium quality pig iron product to the steelmaking industry. Plants can be located at mine sites or in steelmaking facilities.
Pig Iron . Iron pellet ... We finally come into a solution that COREX® process is the most applicable technology, in regards to the availability of our raw material resources. With over a decade Research & Development on environmentally friendly production of hot metal directly from non-metallurgical coal and iron ore (coal reduction process ...
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal. The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to ...
The Corex Process is a smelting reduction process created by Siemens VAI as a more environmentally friendly alternative to the blast furnace.Presently, the majority of steel production is through the blast furnace which has to rely on ever decreasing amounts of coking coal.
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.
Smelting reduction processes are the latest development in pig iron production. These processes combine the gasification of coal with the melt reduction of iron ore. Energy intensity of smelting reduction is lower than that of blast furnace, as the for coke production is not needed and the need for ore preparation is reduced.
In all, the energy supplied by pig iron obtained by the Corex process amounts to 530 kW.h/ton. As a result, electric power consumption decreases when such pig iron is used in an electric furnace (Fig. la), and this is accompanied by a sub-
