Análise da influência geométrica no tempo de homogeneização da temperatura de peças em forno de tratamento térmico

Abstract

In the present work, an important problem in the thermal treatment procedures used in industry was investigated. The influence of the samples geometries on the homogenization time of metallic samples during heat treatment procedures was studied. To accomplish that, a series of experiments with different geometries was conducted. Also, Computer Fluid Dynamics (CFD) simulations were made in order to contribute to the understanding of the problem, in which the same cases that had been experimentally tested were simulated. Based on the results of these simulations, the ways in which several geometrical aspects of the samples influence the time required for the completion of the thermal treatments were discussed. However, some simplifying hypotheses were assumed due to limitations in the experimental procedures.
