Sheet Camber and Cambering of Rolls

The middle of roll becomes hotter than its ends and hence roll diameter in the middle of roll increases. In hot rolling mills this effect is quite pronounced and should be taken into account while calculating the roll camber. In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effect.
