THE THERMAL PROCESSES’ MATHEMATICAL SIMULATION DURING CASTING INTO METAL MOULD OF THE SHORT HOLLOW CYLINDRICFL CASTING
Mathematical simulation is made for thermal processes associated with the removal overheat melt, solidification and subsequent cooling of the short hollow cylindrical casting during its manufacturing by the method of centrifugal casting in metal mould. In the paper the mentioned processes’ mathematical simulation is reduced to the solution of a number of boundary-value problems of heat conductivity theory. Some significant mathematical difficulties caused by the presence of liquid core and moving crystallization fronts or by the domains' complicated geometry etc. are overcome by adopting of the fundamental concept of calorimetric temperature, repeatedly validated both theoretically and experimentally.
