DUAL SEF – ROTOR DEGASSING UNIT
DUAL SEF is a device, designed for aluminum foundries, to carry out degassing treatments with a rotor. The controlled rotation allows the distribution of a flow of micronized nitrogen (or argon) and allows to obtain a more effective deoxidizing action of the salt compared to that obtainable with manual mixing.
Porosity, impurities and oxides are eliminated from the bath. The gas supply varies between 20-30 l/min depending on the shape of the ladle
