Investigation of thermal conditions of the molding process of slurry beryllium oxide

Abstract

Results of experiments and calculations of the mathematical model of the motion and heat exchange of the slurry mass in the annular cavity are presented. Temperature distribution, estimated during the experiments, in the form-building cavity of bushing depending on the molding velocity and heat extraction conditions on the walls of form-building of annular cavity lets us determine the transition from liquid (viscous-plastic) state to solid-plastic one. The experiment results were analyzed and generalized using mathematical model of the thermoplastic slurry molding process. The results of calculation are in agreement with the experimental data, and they show physical validity of the proposed mathematical model of the molding process of the beryllium thermoplastic slurry.
