Mathematical Modelling of Blast Furnace Processes for

The blast furnace is a multi-phase, multi-species moving bed metallurgical reactor with counter-current exchange of heat and mass between gas and solid involving phase changes and complex reactions at high temperatures. Its dynamic behaviour, being typical of a Get price

Coal agglomeration in blast furnace injection coals

However, due to differing feed systems between the DTF and blast furnace, the precise form and extent of agglomeration in the blast furnace remains uncertain. Based on char combustion and gasification analysis, chars characterised by fine agglomerated material are not likely to be problematic for blast furnace operators relative to 'standard' injection coals.

A COMBINED EXPERIMENTAL AND NUMERICAL STUDY OF

2019/11/5Carbonisation is a pretreatment process for upgrading biomass to the so-called biochar or charcoal. Charcoal is a suitable alternative to coal in many fossil-based especially carbon-based industries, for example, the ironmaking blast furnaces (BFs). In this study, a combined experimental and numerical method is used to investigate the influence of biomass pretreatment schemes on charcoal Get price

Durability of traditional plasters with respect to blast

Abstract Blast furnace slag is a residue of steel production. It is a latent hydraulic binder and is normally used to improve the durability of concrete and mortars.

Pellet Degradation Effect on Blast Furnace Performance

A full survey of the laboratory and blast-furnace tests on 2 types of acid pellets is given. From the laboratory tests out in an atmosphere containing hydrogen, it appears that type B, produced out of magnetitic ores, has a far better low temperature disintegration index and a lower reductibility index than type A, produced from a hematite/magnetite mixture. The swelling index, chemical Get price
