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.
