Overcoat: An alternative to bone ash, OverCoat™ is a packing material safely used to prevent metal adhesion on the runner and repair any opening and cracks developed on the refractory surfaces. OverCoat™ produced from carefully selected raw materials, exhibits high performance against metal sticking due to the stability in chemical analysis and the minimum grain size distribution.
Overall: It is used to efficiently remove the slag in the aluminium and alloys. It raises the temperature of the aluminum alloys to allow rapid slag formation and easy separation of the slag from the ductwork. Thus reducing melting losses.
