FIELD: foundry, possibly manufacture of cast blanks of cooled blades of gas turbine engines. SUBSTANCE: method comprises steps of placing mold in heating furnace; pouring melt metal and providing crystallization of casting due to removing heat from mold during two stages; at initial period of casting solidification removing heat from mold with melt metal through bottom cooled metallic crystallizer; after formation of initial structure of casting, extracting metallic crystallizer from under mold; during second stage immersing mold into crystallization chamber with fluidized heat-transfer agent and simultaneously rotating mold around vertical axis with predetermined revolution number in such a way that layer of heat transfer agent neighboring to wall of mold is washed away. It provides uniform distribution of heat transfer agent along cross section of crystallization chamber. EFFECT: improved intensity of heat removal, effective control of heat removal process and enhanced effectiveness of method. 2 cl, 2 dwg, 2 tbl
