In hot rolling processes occur changes in the profile of the rolling mill rolls (expansion and contraction) and\udconstant wear due to mechanical stress and continuous thermal cycles of heating/cooling caused by contact rolled\udmaterial- working roll and the cooling system by water jets in their surface, decreasing their lifetime. This paper presents\uda computational model to simulate the thermal performance of rolling mill rolls. The model was developed using the finite\udvolume method for a transient two-dimensional system and allows calculating the temperature distribution of the rolling\udmill rolls under various conditions of service. Here it is investigated the influence of flow rate and temperature of the\udcooling water on the temperature distribution. The results show that the water temperature has greater influence than\udthe water flow to control the surface temperature of the cylinders
