Abstract
A method of rolling plates from input stock in several successively arranged work steps, wherein, depending on the desired end product, different numbers of n passes are carried out in one or more roll stands, preferably in a hot-rolling reversing stand. From a pass n-k to a pass n-1, greater pass reductions (smaller strip thicknesses) are rolled at the strip beginning than at the strip end, wherein k is a counting number in the range of from 1 to n-1.
