Abstract
A flux for use in galvanizing contains aluminium oxide together with ammonium chloride, zinc ammonium chloride, or zinc chloride. It may also contain one or more other metal oxides, viz. lead oxide, stannic oxide, iron oxide, bismuth oxide, copper oxide, or cadmium oxide, metallic zinc or aluminium, or zinc-aluminium alloys, fluorine compounds, alkali chlorides, and alkali aluminium chlorides. The aluminium oxide may constitute about 1 per cent by weight of the flux. The flux may be used with molten zinc or zinc-aluminium baths, or it may be used on the surface of the molten lead in a lead-zinc galvanizing bath, in which case the zinc layer may contain aluminium. The constituents of the flux may be fused on the surface of the bath or may be applied to the surfaces of the articles to be coated. Where rollers are used to handle the articles, the flux may be used to clean the rollers.
