Abstract: According to the thermodynamic characteristics in the work interface o f the plastic forming of metals, a set of TCR (thermal contact resistance) experimental system under the conditions of high temperature and high pressure has be en designed. The interrelations between the thermal contact resistance (TCR) and its influence factors such as contact pressure etc, are obtained. A modified coefficient E is introduced to consider the relative slide in the contact interface. Then the interfacial TCR calculating model, which suits to the special conditions of `high temperature+plastic rheology' and frictional contact such as continuous roll casting process, is established.
