FEATURES OF THE DISTRIBUTION OF HEAT FLUXES IN THE ANODE-VAPOR-GAS SHEATH SYSTEM IN ANODIC ELECTROLYTIC HEATING

摘要

An expression for the density of the heat flux acting between a vapor-gas sheath and a vertical cylindrical anode has been obtained from solution of the heat-conduction equation in the vapor-gas sheath and experimental measurements of he anode-specimen temperature. It has been shown that the heat flux from the sheath to the anode acts just in the lower part of the system. In its upper part, heat fluxes are directed from the anode to the sheath, which limits the possibility of applying the heat-transfer coefficient to description of heat exchange in anodic heating. The values of the vertical temperature gradient in heating of the cylindrical anode and the fraction of heat coming into it have been measured.
