FIELD: metallurgy, repair of rollers of continuous casting machines or any other parts. SUBSTANCE: for increase of resistance of shrouded parts thanks to prevention of shroud slipping in process of usage rings of shroud are heated up to temperature not above 570 C and are cured at specified temperature in the course of ( 1.1-4.0)δ min, where δ is thickness of ring wall, mm. Depending on design of outer surface of roller barrel all rings of shroud are put simultaneously or in turn starting from midpart of roller. EFFECT: increased wear resistance of shrouded parts. 2 cl
