Smelting reduction in iron baths
Steel Research, 1989A joint venture between Klöckner‐Werke and CRA was formed to work out the application of coal injection into the iron bath to smelting reduction. In the Hlsmelt process of CRA smelting reduction of prereduced fine ore is to be carried out directly in the iron bath. Post combustion, different coal grades, and metallurgical reactions were investigated in

Behaviour of coal in smelting reduction installation
Ironmaking & Steelmaking, 2000AbstractA model for the behaviour of coal particles under conditions of the ROMELT liquid phase iron reduction smelting process is presented. Values of the main parameters of the model have been determined on the basis of experimental data. The model allows evaluation of the content and fractional composition of the coal mixed into the slag, for ...

Mathematical model for post combustion in smelting reduction
Steel Research, 1996Post combustion in the top space of iron bath smelting reduction furnaces is analysed with three‐dimensional mathematical modelling. Momentum transport and continuity equations in combination with a k‐ɛ model of turbulence are numerically solved for the gas flow field.

Evolution or revolution to produce steel : direct reduction vs. smelting reduction
Revue de Métallurgie, 1991Reduction is an important step in steelmaking. Two routes have practically been developed : a smelting reduction route, and a melting route.This situation can be changing :– gradually (« evolution »),– or radically (« revolution »), with the research effort.The article aims at giving the state of the art, with regard to direct reduction, smelting ...
