Abstract

1496946 Rolling sheets NIPPON KOKAN KK 8 July 1975 [6 Aug 1974] 28653/75 Heading B3M The flatness of a metal sheet 5 being rolled between rolls 1 is controlled by changing the tension distribution across the width of the sheet by means of short rollers 4 which are individually vertically displaceable against the sheet. A local increase in tension in the sheet produces a slight decrease in reduction produced by the rolls 1 in the same region of the sheet. Sensors 6 detect any non-flatness in the sheet and are used to regulate the rollers 4 to produce the desired tension changes. An auxiliary roller 5 may be located on the side of each set of rollers remote from the mill rolls, the roller being cylindrical or crowned and serving to regulate the basic tension acting on the sheet. The method can be applied to hot, cold, or skin-pass rolling.
