Abstract
Inventia se referta la o metoda de tratament termic al valturilor de lucru din otel de scule aliat, pentrz fabricarea profilelor goale din metal, pe a caror periferice s-a prelucrat un profil de calibru unuiform sau neuniform. Scopul inventiei este marirea duratei de functionare a valturilor prin intensificarea efectului de calire în zona de calibru prelucrata. Valtul de lucru, austenitizat, este solicitat într-un timp scurt, în pozitie orizontala, în zona formei calibrate, cu o ceata de apa sub presiune mare, prin care stratul de tunder sau de sare, aflat pe calibru, este îndepartat. în pozitie orizontala aflat în baia de calire cu ulei valtul de lucru este solicitat suplimentar, în zona formei de calibru, cu diferiti curenti de ulei sub presiune mare, care sînt îndreptati aproape tangential pe suprafata formei de calibru.
