Abstract (en)

[origin: EP0839587A1] The method concerns rolling of thick sheet metal from a preliminary material in several successive stages, with different numbers of passes (n) according to a particular desired end product, in one or several roll stands, but preferably in a single hot revers-ing stand. The method is characterised by the fact that from a pass (n-k) onwards to a pass (n-1), where k lies in the range from 1 to n-1, the pass reductions produced at the beginning of the strip are greater than those produced at the end of the strip.
