The paper presents the results of the experiments on the solidification of superalloys in shell moulds. The analysis of heat transfer during the solidification of castings in ceramic moulds was carried out theoretically and confirmed by the results of earlier experiments conducted on model shells. Results of experimental temperature measurement were compared with numerical calculations (performed using the ProCast software) and corrections of the calculation parameters were proposed. A model of structure simulation was verified on a selected real casting. It can be assumed that simulating the structure will be a theoretically and computationally demanding problem.
