The smelting reduction in the blast furnace is the most important option to produce the pig iron (raw material for the production of steel), although the Corex …
Related to a unit amount of pig iron, these quantities are called energy characteristics of the blast-furnace assembly. They may be used to assess the energy process effects of applying COREX gas in the blast-furnace process.
COREX is one of the methods used for production of hot metal from iron ore. It is a coal-based process.[1] The method was developed by Primetals as a more environmentally friendly alternative to the blast furnace.[2][3] A corex process eliminates the need to prepare iron ore and coal, and can be used fairly directly in a smelting reduction process.
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 …

Corex Process for Production of Iron. During the late twentieth century, several new initiatives have been taken for the development of the smelting reduction technology which can become …
The Corex process is a more environmental-friendly method of pig iron production than the blast-furnace process. Additionally, this technology is accompanied by production of a fuel gas with a LHV … Expand
This process bypasses cokemaking and requires less charge preparation, but usually needs a pre-reduction step. COREX, FINEX, and HISMELT are major examples. The more fully commercialized COREX and FINEX may be considered as processes that separate the shaft and the lower smelting sections of a blast furnace . Pre-reduction of iron ore is first ...
One of the modern technologies of producing pig iron (p.i.), connecting the processes of the reduction and smelting, already applied practically, is the Corex process [1], [2]. In the course of the passed twenty-five years several installations based on the Corex process have come into being [3].
This document summarizes several alternative iron making technologies to the traditional blast furnace process, including direct reduction processes like FINEX and HIsmelt, and smelting reduction processes like Corex and Ausmelt.
Smelting-reduction process for ironmaking is a smelting process to produce liquid pig iron without using blast furnace ironmaking method. Smelting reduction falls into one-step and two-step methods according to the presence or absence of prereduction unit. ... among which the COREX process has been industrialized, but the technology …
The rapid development of gas-based (Midrex, HYL, ENERGIRON) and coal-based (DRyIron, Iron Dynamics, Fastmet, Fastmelt, Itmk3) technologies for the direct production of iron and blast-furnace-less iron metallurgy (COREX, FINEX, Hismelt, ROMELT) in the second half of the 20th Century failed to lessen the dominant role of …
From a wider point of view, an additional production of pig iron as the Corex process replaces the pig iron produced in other blast furnaces, which results in further decrease in CO 2 emission. There are many possibilities of utilizing both Corex and blast-furnace gases inside the integrated system consisting of Corex installation, blast ...
Smelting reduction processes are used to reduce iron ore to produce pig iron. The process combines coal gasification with melt reduction of iron ore, eliminating the need for coke production and ore preparation, thereby lowering energy requirement in comparison to a Blast furnace.[1][2]
Three types of iron input materials for both processes are liquid hot metal or in solidified form as pig iron, direct reduced iron (DRI) and hot briquetted iron (HBI) as well as steel scrap. Hot metal, pig iron, DRI and HBI are iron materials, which have to be produced from iron ore by the so-called ironmaking technologies.
Cleaner Iron Production with Corex Process. A special manufacturing process is making the production of iron much more environmentally friendly. The outstanding feature of the "Corex process" is that it uses conventional coal instead of coking coal, the customary ingredient.
The COREX®-process is the first commercially operating smelting reduction process for the production of pig iron. For this reason, it can be seen as an alternative to the common industrial iron-making route via the blast furnace. For both, the COREX® melter-gasifier (MG) and the blast furnace, good gas-solid contact is essential …
For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.
The Corex process combines coking plant, sinter plant and blast furnace into a single iron making unit. ADVANTAGES OF COREX. Product quality – hot metal quality suitable for all steel applications. Economic benefit – low investment and operational costs due to the …
