ABSTRACT:
A method for rolling out a slab, preferably a slab produced by continuous casting, to form a billet having a square cross section, in which the width of the slab is reduced by repeated powerful edging passes, a temperature drop starting from the central region of the slab being provided during rolling, for example by spraying the edge regions of the slab with coolant, in order to give the edge regions greater deformation resistance and thus to prevent bulges at the edge regions. The bulge occurring in the central region of the slab is rolled away by guide rollers located at right-angles to the edging rolls. A rolling mill with suitable heating means is also provided.
