ABSTRACT:
A thin metal sheet is produced in a continuous rolling operation by passing the hot workpiece through a succession of size-reducing compression roller stands. Between the furthest downstream stand and the stand immediately upstream therefrom there is provided a stretcher which decreases the workpiece's thickness between 5 and 15%, whereas the furthest downstream rolling stand merely reduces the thickness between 3 and 6%. Thus irregularities in planarity and the like are completely eliminated by the stretcher and the furthest downstream rolling stand serves merely to accurately size the workpiece.
