The paper proposes the structure and the main automated system modules for calculating the annealing modes of glass products. There is the problem of modeling temperature fields for cylindrical products with asymmetric convection-radiation heat exchange with the environment and enclosing surfaces of technological equipment. The author formulated the possibility of solving the two-dimensional temperature problem in the Matlab programming environment. There was the parabolic function in the performance of the temperature field-modeling problem in cylindrical glass products. This is one of the Matlab tools for solving differential equations of parabolic type with complex boundary conditions. There are the programs based on the standard fmincon function in Matlab that allow to identify the coefficients of artificial convective heat exchange between the air and the product surface in each of the zones by using the determinate thermal material characteristics and the temperature-time regime parameters in the annealing furnace. There is a parameter identification example of the convective-radiation heat transfer in the sort glassware (glasses) annealing furnace based on the temperature field-modeling program in Matlab. The author considered the program development features associated with the need to take into account the changing initial and boundary conditions at each temperature-time stage annealing of the product. There are the program codes of the main program, the modeling temperature field functions the CilinderHolParabolic1 and the boundary conditions boundaryFileHolParabolic1. The author studied the program results and demonstrated a good match of the convective heat transfer coefficients with their physically reasonable values in artificial convective heat exchange in annealing furnaces of glassware. The attained condition identification results of the convective-radiation heat exchange with the environment and enclosing surfaces we can use to optimize the heat treatment of cylindrical products.
