<p>PURPOSE:To control easily the shape of a rolling material, by using variable crown rolls as backup rolls and providing plural stands of multiple roll mills whose work rolls are made small in diameter for constituting a continuous rolling equipment. CONSTITUTION:Variable crown type rolls are used as the upper and lower backup rolls 1, 1 and 2, 2 of a multiple rolling mill, and also the work rolls are made small in diameters. Or the lower and upper backup rolls 1, 2 are formed into different variable crown shapes, or work rolls of different peripheral speeds are constituted by making the work rolls small and different in diameters. Thus the shape and the profile or a rolling material are easily controlled by using a continuous rolling equipment equipped with plural stands of said multiple rolling mills.</p> |
