Slag and its Role in Blast Furnace Ironmaking – IspatGuru

Slag formation is to be confined to a limited height of the blast furnace and the slag must be stable. The slag is to provide good permeability in the zone of slag formation. The melting point of the slag is to be neither too high nor too low. The final slag is to be fluid enough so that it is possible to drain it through tap hole,

Blast Furnace Slag | National Slag Association

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

Slag - Wikipedia

The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.

Role of Slag in Converter Steelmaking – IspatGuru

METALLURGICAL USES FLUXES FOR METALLURGY

The function of the slag might vary at different stages within a process prior to final melting. For example, the slag composition and behavior will change as materials descend in the iron blast furnace, or as they melt in the early stages of formation of steel- making slags. Selection of the chemistry for a slag might be in-

Blast Furnace - an overview | ScienceDirect Topics

The blast air causes the iron oxides, flux, and coke to react and iron, carbon monoxide and blast-furnace slag is produced. The molten iron and blast-furnace slag is collected at the base of the furnace, while the gases are recirculated for fuel in the sinter process, after separation of particulate material (Cooper, 2005).

Steel Slag - Material Description - User Guidelines for ...

High-grade steels have high carbon content. To reduce the amount of carbon in the steel, greater oxygen levels are required in the steel-making process. This also requires the addition of increased levels of lime and dolime (flux) for the removal of impurities from the steel and increased slag formation.
