Conclusions
Functions were derived for the stresses occurring in a lining being heated up which make it possible to determine the thermoelastic stresses at a given point through the lining at a given instant during the inertia period of heating.
Extrema analyses of the stress functions gave the maximum tension and compression stresses during the heating-up process.
Equations were derived for calculating the thermal flux on the lining for the permitted level of tension and compression stresses. The thermal power for heating the lining can be calculated from the thermal flux on the lining.
