FIELD: process engineering.
SUBSTANCE: invention can be used for production of hexahedral pies for sealed storage in nuclear power station ponds and transportation of used nuclear fuel. Cast produced by electroslag remelting, turned to remove foundry defects, heated to ductility storage and pierced at cross-rolling mill to sleeves. Mandrel with ring is fitted at pilgrim mill mandrel head. Cylindrical carbon jar washer is fitted on mandrel to be fitted in said sleeve. Then, tapered cylindrical carbon jar washer is fitted on the mandrel and centered relative to mandrel axis by taper section of carbon jar washer. Assembled sleeve is shaped at variable-profile gages to steel pipe with seed end and pilgrim head fitted on carbon jar washers.
EFFECT: lower metal input and higher efficiency.
