Effect of Oxide Scale on Interfacial Heat Transfer during Slab Hot Rolling

The hot rolling of slab was studied with the aid of elastic plastic and thermomechanical couple FEM. On the basis of experiment and numerical analysis, the physical models for interfacial heat transfer during hot rolling were established. The results indicated that the deformation, cracking and decohesion behavior of the oxide scale have considerable effects on temperature distribution of slab during hot rolling.
