ABM Proceedings

Within the scope of the Austrian K1-MET programme this work aims to investigate the char conversion behaviour by its usage under conditions in Corex/Finex smelting reduction processes. Char samples were produced by pyrolysis of two coals and four coal briquettes; the thermo shock conditions at 1,000C were simulated. Get price

The Corex Process Part Right Steel. nbsp 0183 32 The most interesting feature of the Corex process is the separation of iron reduction and smelting operations into two separate reactors which are reduction shaft and melter gasifier therefore it is a two stage process The Process The Iron ore is directly charged into the reduction shaft along with limestone and dolomite additives Get price

Corex – Wikipedia

Das Corex-Verfahren ist ein zweistufiges Schmelzreduktionsverfahren („smelting-reduction"), in dem Roheisen auf Basis nicht verkokter Kohle und Eisenerzen hergestellt werden kann.

The FINEX Process :: Total Materia Article

The DRI fines are then hot-compacted to hot-compacted iron, transferred to a charging bin positioned above a melter gasifier where smelting take place. The tapped product, liquid hot metal, is equivalent in quality to the hot metal produced in a blast furnace ore Corex plant. Get price

CFD‐DEM Study of Heat Transfer in the Reduction Shaft of Corex

Corex Process

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. That is coal which has been cooked in order to remove impurities so that it is superior to coal. In addition, the Blast Get price

Environment

Environment-friendly Corex process of iron and steel making: The highlight of the process is it does not require coking coal. The process differs from the conventional blast furnace route; where un-treated non-coking coal can be directly used for ore reduction and melting work, eliminating the Get price

Production of Pig Iron by Using the Romelt Process

The spent heat in the smelting and reduction process of the charge material is higher than the heat from carbon burning to carbon monoxide (CO) near the lower tuyeres. Thus, the main feature of this process is what happens in the post-combustion (where carbon monoxide (CO) is oxidized to the second carbon (CO2) and hydrogen (H2) to water vapor Get price

Briquetting of Coal Fines for Use in Smelting Reduction

Nov 01, 2013COREX/FINEX smelting reduction processes require lumpy coal for stable operation. The screened-off coal fines must be briquetted by means of binders to be utilizable for the COREX/FINEX processes. Optimal binder types, their amount, and briquetting conditions are identified by systematic experimental analyses. Experimental work is based on a critical review of Get price

Copper Smelting Process

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised Get price
