1 . DESCRIPTION
Protecting and drossing-off flux for aluminium and its’alloys.
2. PROPERTIES
Physical state: Solid, crystalline powder .
Density: 1.1 gr/cm³
3. OTHER CHARACTERISTICS
Hygroscopic. Composition: Salt mixtures highly composed by alcaline
chlorides. It contains also some fluoridated salts.
4. METHOD OF USE
Tekpural A is employed to protect and dross-off aluminium and its alloys
melted in reverbatory furnaces or crucibles The temperature range for optimum
drossing off reaction is between 720 °C and 760 °C. The addition amount
can vary between 0,2% and 0,5% of the weight of the treated melt.
5. ADVANTAGES
The application during melting of a protective cover of TEKPURAL A
on aluminum alloys significantly reduces the formation of dross. The final
drossing-off, such as injection by fluxing wands, results in powdery dross
which poor in metallic aluminium and easy to remove from the melt with a suitable perforated tool. Therefore it is very
useful for economics of the melting process by preventing aluminum being
trapped in the dross.
6. PACKING
In bags of 25 kgs. 7. STORAGE
Store in the dry place in the original sealed packing.
8. SAFETY
Subject to moisture pick up. Avoid contact with the skin and inhalation
of dust and fumes evolved. Work with forced fumes draught.
