Presented are solutions of some problems typical for thermalphysic processes in an ore-smelting electrothermal reactor. Its reaction bulk comprises several zones of diverse phase compositions, where proceeding of physical-chemical target transformations is intensifying by turbulent energy transfer. Chemical reducing processes are proceeding on isolating the gas phase, which is bubbling the melt and actively transporting energy and reaction products. Problems of analysis of thermalphysic processes in a reaction zone and in separate elements of electrothermal reactor are considered in a two-dimensional formulation. Obtained are analytical solutions for describing thermalphysic processes in circumstances of the target product manufacturing. There is carried out structure analysis of a reaction zone and a raw material melting zone. Analytical solutions are obtained for problems of heat exchange in self-baking electrodes with regard to physical-chemical processes which take place during sintering. The electrode temperature field analysis makes it possible to guarantee reliable operative conditions and allows to form conditions needed for providing the required degree of anode paste hardening. The derived solutions may be used as references ones for numerical analysis of thermalphysic processes in a bath of oresmelting reactors.
