An analytical model for the prediction of hot roll temperatures in a hot rolling process [PDF]
Materialwissenschaft und Werkstofftechnik, 2016 Temperature variations in the hot roll during a hot rolling process were analysed by solving heat conduction equations for boundary conditions using an analytical method. The analysis was conducted in a steady‐state regime, taking into account the effects of process parameters such as the contact surface, roll velocity and various cooling boundary ...
