This material is intended for dilution of slag in casting ladle during out-of-furnace processing in a ladle furnace installation.
-briquettes 30-100 mm (fraction is under discussion)
-powder, in PP bags 10-20 kg.
Al2O3 60 – 80;

Provides high slag fluidity, its refining and assimilative capability.
Usually is delivered to the jet during the metal tapping from furnace to ladle, or delivered with lime and other additives after filling the ladle.
- Metal desulphurization process speed increases by high slag activity.
- Avoidance of using fluor-spar.
- Decrease of negative impact on refractory lining.
- There are best conditions for diffusion metal deoxidizing through slag in a ladle-furnace installation.
