Previous issue date: 1978 / Abstract: The mould geometry's influence on metals solidification was considered the main factor investigated in this work. Thus extensive bibliographycal review work was carried out on the influence of the cylindrical mould geometry wich yielded very lit ttle information on the matter, and presented rather complex models for solidification of cylinders. Again it became apparent from th~s study that analytical models were not viable for technological solutions due to their mathematical complexity. To solve this problem, experimental equations with known parameters were applied with the intention of determining the correctian factors. so as to equate these experimental equations with the experimental datas obtained in our investigations. The experimentaIs results were obtained primarily for aluminium with two different interfaces metal/mould conditions. In arder to investigate the thermal resistence at these interfaces. The apparatus used in these experiments were: Cooled chill mould.for the purpose of determination of the solidification kinetics of cylinders. and Massive interna I mould to verify the heat build-up lin the mould as well as the salidification kinetics of the metal / Mestrado / Mestre em Engenharia Mecânica
