Abstract

A knowledge of the temperature distribution in the roll-gap during hot rolling is essential for accurate prediction of the roll force and of the microstructure in the rolled strip. Theoretical models that are used to predict temperature distribution in the roll-gap require accurate values of the coefficient of heat transfer between the surfaces of the roll and strip (hRS). Measured values of hRS applicable to hot rolling of aluminum are reported. The effect of different pass reductions, roll pressure distribution and lubrication on the coefficient of heat transfer is examined.
