An improved approach to the simulation of the radiative heat exchange in a furnace is proposed. This approach is realized with the use of the computer program REFORM based on the well-known Monte Carlo ray tracing algorithms. The method proposed allows one to determine the factors of radiative heat exchange in furnaces for which the method of direct numerical integration is difficult to use due to their geometries. The indicated REFORM program was validated and the results obtained with it were compared with corresponding existing solutions. It has been established that the approach proposed makes it possible to more accurately represent the radiative heat exchange between a steel load and its surroundings.
