special granulate for Al-Si-cast-alloys
easy binding of oxids in the slag
Addition quantity approx. 0.1%.
 
 
In the molten state, aluminum, wrought and cast alloys tend not only to form oxide and absorb hydrogen, but also to form undesirable dross and aluminum oxide foam, which has an extremely high metal content. The granules bind oxides and transport them to the surface through a flotation process, where they can easily be skimmed off as slag.
 
Application:
Depending on the amount of melt, approx. 0.1 weight - % is added,
i.e. for 1 kg of melt, approx. 0.01 kg (=1g) is required.
Shortly before pouring, the required amount is carefully stirred into the melt.
After a short reaction time of approx. 1-2 minutes, the "dross" can be skimmed off with a preheated spoon and watering can begin.
