FIELD: metallurgy, possibly manufacture of double -layer rolling rolls.
SUBSTANCE: method comprises steps of casting outer layer of roll in the form of hollow cylinder by squeezing at crystallization under pressure and placing it into casting mold; before placing cylinder into casting mold covering it from inside with thermosetting composition and from outside - with refractory pickup prevention composition; after placing cylinder into casting mold, pouring it along outer surface with sand; casting metal of core part and of journals.
EFFECT: high-strength joint of working layer with metal of central part, lowered volume of mechanical working of roll barrel due to producing accurate-size castings.
