A Mathematical model has been developed to predict the temperature profile of the strip in the Run-out Table (ROT) of the Hot Strip Mill (HSM) at Tata Steel, India. The prediction of temperature profile across the thickness of the strip shows good results. A simple correlation for heat transfer coefficient has emerged from this study. A polynomial as a function of strip surface temperature has been found to represent the heat transfer coefficient at water-strip interface accurately. The salient features of this paper are described as follows: 1) An off-line model has been developed to predict the through thickness temperature of the strip in the Run-out Table of a Hot Strip Mill. 2) The heat transfer coefficient at water-strip interface on the water-cooled zone over the bed of Run-out Table can be considered as a polynomial of strip surface temperature. Tests have been performed to validate the correlation of heat transfer coefficient against several thousand coils.
