ATS – ESR FLUX
In order to protect the slag makers to be used in the ESR process from atmospheric effects, we need to cut off their contact with air. For this reason, ATS Metalurji has secured its slag makers against atmospheric changes by using sealed (gasketed) sheet metal barrels and sealed aluminum packaging.
Slag has an important role in controlling inclusions in the ESR process. The chemical and physical properties of slag also have a great impact on the removal of inclusions. The role of the slag includes;
- It controls the oxygen level and chemistry of the molten metal,
- It provides the heat required for the electrode to melt by creating resistance,
- Removing sulfur content of the steel,
- Lubrication for the copper mould/Ingot interface and controlling horizontal heat transfer between the ingot and the mould.
