Alternative Iron making processess - SlideShare

Jan 18, 2014· COREX PROCESS Charge is charged into a reduction shaft where they are reduced to direct reduced iron (DRI) by a reduction gas moving in counter flow. Discharge screws convey the DRI from the reduction shaft into the melter –gasifier. In Melter-gasifier final reduction and melting takes place. Hot metal and slag tapping are done as in

FINEX (steelmaking process) - Wikipedia

FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO.Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke.Elimination of preliminary processing is claimed to make the plant for FINEX less expensive to build than a blast

Raw materials for Corex and their influence on furnace

Jul 18, 2013· The Corex process has been developed as an alternative to BF iron-making, which uses non-coking coal and a small amount of coke as fuel, and pellet/lump ore as iron-bearing feed. JSW Steel operates two Corex units each of 0⋅8 Mtpa, commissioned in 1998 and 2001 respectively.

Minimization of Exergy Losses in the COREX Process

Oct 12, 2011· The COREX process is being projected as an alternative for blast furnace iron making. The coal consumption of the COREX process is large with a net fuel rate of ~1000 kg/tone of hot metal (THM). The reason for a higher net fuel rate of the COREX process compared with the net coal rate for the blast furnace process has been investigated.

MIDREX® — THE LEADING DRI PRODUCTION PROCESS

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). The Midrex technology is highly adaptive to our customers

Emerging Technologies for Iron and Steelmaking

The Corex process, 24 commercialized by Voest Alpine, coines 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.

MIDREX® Process - Midrex Technologies, Inc.

May 04, 2021· Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H ₂ and CO content. These gases react with the iron oxide in the iron ore and convert it to metallic iron, leaving H ₂ …
