FIELD: production of cast products, namely centrifugal casting of copper alloys.
SUBSTANCE: method comprises steps of mixing ultra-fine powder of zirconium dioxide produced by plasma-chemical process and taken in quantity 15 - 20 mass % with technical oil; applying prepared mixture by layer having thickness in range 0.05 - 0.15 mm onto surface of casting mold preliminarily heated up to temperature 150 - 170°C. Such coating has melting temperature higher than that of melt metal.
EFFECT: improved heat insulation properties of coating, elimination of metal sticking to surface of chill mold and of burnings of cast pieces.
