Abstract
The invention relates to a method for processing a metal slab or billet, in which the slab or billet is passed between a set of rotating rolls of a rolling mill stand to roll the slab. According to the invention, the rolls of the rolling mill stand have a different peripheral velocity, the difference in peripheral velocity amounting to at least 10% and at most 100%, and the thickness of the slab being reduced by at most 15% for each pass or the diameter of the billet in the plane of the rolls being reduced by at most 15%. The invention also relates to a plate or billet produced using the method, and to the use of this plate or billet.
