A mathematical model of the temperature field distribution in an intermediate capacity of the electron-beam furnace taking into account the electron beam power, its parametric scan functions, water-cooling parameters, phase transformations of the treated material, and the convective flow of the melt from its feeding place to pouring into the crystallizer is created. Program software making it possible to find the quantitative characteristics and visualize the heat flux distribution over the scan surface and the unsteady temperature field in the intermediate capacity volume is developed. Examples of modeling the temperature field distribution and the position of the solid-liquid interface in the intermediate capacity at various electron beam powers are shown.
