ABSTRACT:
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.
