The article presents a mathematical model of the heat transfer process when heating metal in a furnace, which describes the thermophysical processes that occur when using industrial technology for heating castings. A simplified model of convective and radiant heating of metal in a furnace, which is based on conventional differential equations, allows to calculate the heating time of the metal. It allows you to evaluate the process of heating the metal in the furnace and find its optimal parameters. The model is widely used and can be applied to study the process of heating the casting of any metal or alloy in the furnace. The adequacy of the model is confirmed by comparing the obtained results of estimating the parameters of the model with experimental data.
