Abstract

A numerical study of the process of continuous combined casting and pressing of experimental aluminum alloy AK12 at various capacities of the continuous combined casting and pressing semi-industrial unit was carried out. A quantitative assessment of the influence of the heating rate of the crystallizer on the temperature and time characteristics during the transition thermal process is given. The heat engineering zones characterized by different intensity of heat exchange between the melt and the walls of the crystallizer are determined. It is shown that increasing the semi-industrial unit performance reduces the duration of the transient thermal process when starting from a cold state until it reaches a stationary thermal mode. The dependence of the time when the unit reaches a stationary thermal mode on the rotation speed of the horizontal crystallizer is obtained
