The dependence of the temperature distribution during hot rolling of a steel slab on the speed of rolling, reduction and initial temperature is investigated. It is observed that while the center of the slab cools, the surface loses heat at a much higher rate following which significant reheating occurs. Because of that different parts of the slab receive significantly different thermal-mechanical treatments, possibly resulting in a nonhomogeneous product.
