A mathematical model of conjugate heat exchange in heating 
furnaces with a moving bottom (ring furnaces and walking-beam furnaces) 
has been developed. The model allows one to determine the heating 
of steel blanks in these furnaces with account for all mechanisms 
of heat transfer in the high-temperature working region of a furnace, 
in its lining, and in the steel blanks. On the basis of this model, 
a more economical regime of operation, as compared to the existing 
ones, has been calculated for a walking-beam furnace and comparative 
analysis of the operating characteristics of a ring furnace and a 
walking-beam furnace has been performed.
