corex process for pig iron

Starting in 1979, VOESTALPINE AG begins work on developing the socalled "COREX process" in cooperation with Korf Engineering , a German company in which it holds a 49 percent interest; this process makes it possible to generate pig iron directly from nonmetallurgical coal and iron ore in inexpensive and environmentally friendly ways ...

JSW Steel claims to be the first Indian company to adopt the corex process. These pig irons are removed of its impurities and alloyed to limit the presence of phosphorous, carbon, sulphur and any other impurities present to meet the standards IS 1786: 2008 and ingots are made which meets the standards. These ingots are then processed.

With over a decade Research Development on environmentally friendly production of hot metal directly from nonmetallurgical coal and iron ore (coal reduction process), founded by Korf Engineering VOESTALPINE AG in 70s, COREX® process convincingly came into a commercial in the late 90s and currently operated by several worldwide steel ...

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements.

Technical Advisor, and the Pig Iron SubCommittee, chaired by Rodrigo Valladares, CEO ... Process of reducing iron ore using a reducing agent such as coke, charcoal, etc. ... as well as by alternative iron making technologies such as Corex and ITmk3.

Another way to create steel from pig iron is the Bessemer process, which involves theoxidation of the impurities in the pig iron by blowing air through the molten. ...

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 technologies considered herein can be

furnace iron. The COREX process does use coal directly, but is still capital‐intensive, requiring pellets or lump ore, and some coke, and producing excess energy (off‐gas) that must be used for the process to be economical. The FINEX variant of COREX (developed by POSCO) uses fine ore instead.

Their diameter ranges from IRON PRODUCTION to mm. Iron and Steel production – The iron and steel production process can be subdivided into 3 Blast Furnace (pig iron) – Blast furnace (Figure 2) is a subprocesses: ironmaking, steelmaking and steel process for producing liquid raw iron by smelting pellets manufacturing.

Related to a unit amount of pig iron, these quantities are called energy characteristics of the blastfurnace assembly. They may be used to assess the energy process .

DIRECT IRON SMELTING REDUCTION PROCESSES B. ANAMERIC AND S. KOMAR KAWATRA Department of Chemical Engineering, Michigan Technological University, Houghton, Michigan, USA Direct iron smeltingreduction processes have been developed as an alternative to the blast furnace process for making molten, slagfree iron.

Industrieanlagenbau, 1996). The COREX process uses agglomerated ore, which is prereduced by gases coming from a hot bath. The prereduced iron is then melted in the bath. The process produces excess gas, which is used for power generation, DRIproduction, or as fuel gas. The COREX process is estimated to use 15 to 18 GJ/tonne steel net energy

In cooperation with the German company Korf Engineering , in which VOESTALPINE AG held a 49 percent interest, in 1979 work was begun on the development of the socalled COREX process to enable the inexpensive and environmentally friendly production of pig iron directly from nonmetallurgical coal and iron ore (coal reduction process).

around 100 kg/tpig iron, and as a result, the coke ratio decreased only to around 450 kg/tpig iron on average. In contrast, the amount of PCI increased rapidly to reach a level of 130 kg/tpig iron around 1998, lowering the coke ratio to 370 kg/tpig iron, and at its maximum, a monthly average PCI amount of 266 kg/tpig iron was recorded at

The heat is used to smelt iron and the hot gas is transported to the prereduction unit to reduce the iron Fig. 4 MIDREX Process: 1) natural gas; 2) iron ore; 3) oxides that enter the process. Reduced ironoxides (now compressor; 4) scrubber; 5) offgas; 6) air blower; 7) gas similar to DRI) are in turn transported to the smelting reformer; 8) reducing gas; 9) heat recovery; 10) reformer reduction vessel for final .
