Imerys metallurgical active slags are sold under the names AKTIV-DESULFAT, AKTIV-DEPHOSPHAT and GLUTIN SLAG. They are applied during the secondary metallurgy treatment (ladle) and tundish covering, to achieve deoxidation, desulphurisation, degassing and alloying. Furthermore, these slags are applied in the tundish of the continuous casting process.
The benefits of using such slags are:
- Lower sulphur concentrations
- Lower phosphorus concentrations
- Spheroidisation of non-metallic inclusions
- A high degree of purity
- Prevention of re-oxidation
- Absorption and dissolution of impurities from the steel
