The calculation of the temperature field of solidifying walls of the casting is complicated by the necessity of considering the heat conduction equation of heat released during crystallization. One of the ways to solve this problem is to increase the heat capacity of the solidified material so that the heat released as a result of cooling was equal to the heat obtained during the crystallization of the casting wall. The application of equivalent heat capacity values in the finite difference method is carried out by using a piecewise continuous function. As a result of calculations piecewise continuous functions at which the average deviation of settlement values of heats of crystallization from the set does not exceed 0,06% are received, and it is possible to use them in the course of calculation of of crystallization heat in the numerical solution of thermal conductivity problems.
