<p>PURPOSE:To surely control the camber without providing plate thickness differences between right and left by reducing the friction factor in the external side region of a metal cambered by a friction factor adjustment means when a camber is produced in the metal. CONSTITUTION:On the basis of the lubrication condition required for correcting the camber, the lubrication oil of the selected kind is supplied from a nozzle 10a located in the specified width direction between a metal 1 and a work roll 2 by a rolling oil supplying device 9 and a width direction part lubrication oil supplying device 10, and adjustment is executed so that the friction factor between the external region of the metal and work roll 2 of the rolling mill 3A may be reduced. Thus, when a camber is produced in the metal 1 while the metal 1 is rolled in the condition where the movement in the width direction of the metal is restricted on the inlet side of the rolling mill 3B, the external region of the metal 1 is adjusted so that the friction factor between the work roll of the rolling mill 3B may be reduced, leading to the control of the camber of the metal 1 with good precision.</p> |
