FIELD: foundry.
SUBSTANCE: method comprises steps of forming beads (by crimping or pressing) on end surface of bimetallized blank; placing first technological lid inside vertically arranged blank; pouring desired quantity of charge into blank; placing second lid under formed bead; placing blank in centering device of centrifugal machine; subjecting blank to rotation and heating its outer surface till charge melting temperature. In order to provide complete melting of charge, isothermal soaking is realized and then blank is cooled.
EFFECT: simplified procedure for filing blank with charge, enhanced fluid-tightness of blank, improved efficiency of process.
