  • Preliminary Treatment Of Fibers (AREA)

Abstract

Inventia se refera la un procedeu pentru tratamentul termic al sculelor dinh oteluri înalt aliate, în special a cutitelor taietoare utilizate la taierea fibrelor elastice. Procedeul constp din încalzirea sculelor pana la 950 degree gradr cu o treapta de preîncalzire la 550 degree C, racirea realizandu-se în ulei. Dupa calire se aplica o revenire joasa pentru a se obtine o duritate cuprinsa între 60,0 si 62 HRC.
