PROPERTIES: Euroslag

Steelmaking slag (BOS or EAF) mainly consist of dicalciumsilicate (Ca 2 SiO 4), dicalciumferrite (Ca 2 Fe 2 O 5) and wuestite (Fe 1 -x- y,Mg x,Mn y)O z. The physical properties of iron and steel slags depend on the chemistry as well as the cooling condition and can be influenced by processing once the slag is removed from the furnace.

Effect of super-gravity field on metal–slag separation ...

The effects of super-gravity field on metal–slag separation at different gravity coefficients were investigated in this study. In a super-gravity field, the liquid metal concentrated along the direction of super-gravity, while the molten slag migrated and aggregated along the opposite direction thereafter separated from the metal.
