Thermal Analysis of a Cold Rolling Process — A Numerical Approach

Simulation of interface temperature and control of lubrication in the study of friction and wear in cold rolling

“…Indeed the thermal studies for cold rolling were generally carried out on tandem mill with notably the use of bigger work rolls than on a Sendzimir one [3,4,7]. According to the value of the convective coefficient used to define the cooling by emulsion, the mean interface temperature is evaluated between 100°C and 160°C [7]. As a conclusion, the mean contact temperature cannot be defined accurately for process analysed herein: a temperature of 120°C will be first tested.…”

“…Therefore, considering all these factors, it is quite difficult to determine the mean contact temperature corresponding to the studied process from literature. Indeed the thermal studies for cold rolling were generally carried out on tandem mill with notably the use of bigger work rolls than on a Sendzimir one [3,4,7]. According to the value of the convective coefficient used to define the cooling by emulsion, the mean interface temperature is evaluated between 100°C and 160°C [7].…”

Analysis of interface temperature, forward slip and lubricant influence on friction and wear in cold rolling

“…The thermal studies for cold rolling were not exactly carried out in the same conditions of geometry, material or lubrication. Khan et al [14] carried out a coupled heat transfer analysis taking into account cooling by emulsion applied to a tandem mill with notably the use of bigger work rolls than on a Sendzimir one. The contact temperature was evaluated between 110 and 160 • C according to the value of the convective coefficient used to define the cooling by emulsion.…”

Effect of Water Jet Orientation and Other Controlling Parameters on Work Roll Temperature in a Hot Strip Mill

“…Two-dimensional finite element analysis has been carried out to predict the temperature field and the effect of various factors including the thermal relationships to the work roll and the metal slab, and the rolling speed [6]. Recent work with the coupled analysis of roll and strip temperature in cold rolling [7,8] has been reported in the literature. Sensitivity of thermal crown due to the change of roll gap heat transfer coefficient [9] has also been reported.…”

“…Researchers over the past two decades have carried out extensive investigation to develop models [1][2][3][4][5][6][7][8][9][10][11] for the prediction of roll temperature profile and means to reduce the thermal fatigue during rolling. Studies have mainly focused on the temperature profile across the boundary layer of the roll surface, 3-5 mm depth from the surface to the center.…”
