This work presents a theoretical-experimental study on the solidification of metals, initially at a temperature above the melting point, in cooled cylindrical moulds. A literature survey was carried out regarding the heat transfer methods applied to solidification in metal/mould systems. Using a radial water cooled device simulating the solidification of cylindrical geometries, experimental values of the solidified thickness as function of time were obtained. A method was developed to analyse the solidification kinetics of superheated metals in cooled cylindrical moulds and the predictions furnished by this method were compared with the experimental data. Possible applications of the proposed method to the solution of practical problems in the foundry process 3re presented. Finally a comparative study of the solidification kinetics of solidified metals in plane, cylindrical and spherical geometries is presented.
