In a method and apparatus for producing sheets or plates by hot rolling slabs in a number of passes, the slabs are alternately deformed more strongly and less strongly between a pair of rolls at least in one pass, and when the slabs are less strongly deformed, a condition according to which alpha ' is equal to or smaller than rho is observed, while when the slabs are more strongly deformed, a condition according to which rho is smaller than alpha smaller than 2 rho is observed, alpha and alpha ' being the angles of engagement and rho being the angle of friction, and differences in thickness in longitudinal direction of the slabs are levelled out in a subsequent pass. |
