FIELD: foundry, centrifugal casting in particular; manufacture of multi-layer vessels, pipe lines, bottles, connecting parts and other articles.
SUBSTANCE: proposed method includes placing the thermit mixture in cavities of article, followed by rotation, initiating of exothermic reaction, melting of thermit mixture, cooling of external surface of article and crystallization of molten thermit mixture. Thermit mixture contains additionally fluid material. Cooling of external surface of article is continued till temperature of its internal surface gets equal to melting point of metal of article.
EFFECT: reduced thickness of coat; improved control of heat removal.
