PROCESS AND DEVICE FOR CENTRIFUGAL CASTING OF COPPER AND COPPER ALLOYS

摘要

Method for centrifugal casting of copper and copper alloys or other oxygen sensitive alloys, in particular bronze, at least a flux is incorporated in the mold in order to avoid or limit the formation of a layer oxide on the inner surface of the molded part. Is applied as a flux on the inner surface of the still liquid casting, immediately after the casting operation, the solid borax, preferably in powder form, optionally together with mixtures of fine metal particles affinity for oxygen, for example Mg, Li, Cer and / or graphite powder and / or chamotte and / or charcoal, all in the form of a layer of a thickness of 0.5 to 4 mm, preferably 1 to 3 mm.
