Abstract

Inventia se refera la un procedeu pentru realizarea arcurilor inelare cu caracteristici mecanice îmbunatatite, în urma unui tratament termic combinat cu deformare plastica. Semifabricatele dupa laminare pe un laminor circular sau pe un utilaj corespunzator, de la temperatura de 850 degree C, se racesc timp de 5 la 20 s în ulei, dupa care sunt supuse unei reveniri la 400-480 degree C, apoi de la aceasta temperatura sunt calibrate cu un grad de reducere de maximum 5%.The invention relates to a process for making annular springs with improved mechanical characteristics following a heat treatment combined with plastic deformation. Semi-fabrics after rolling on a circular mill or on a suitable machine at a temperature of 850 ° C are cooled for 5 to 20 seconds in oil, then subjected to a return to 400-480 ° C, then at this temperature are calibrated with a reduction rate of maximum 5%.
