Abstract
PURPOSE: To prevent defects of tearing at the trailing end of a thin plate rolling material which occurs at the time of pass-through by bevelling the rectangular parts at the trailing end of the rolling material prior to cold rolling of rollilg material.
CONSTITUTION: Prior to cold rolling with tandem mills, both or one of the rectangular parts of the trailing end of a rolling material 1 is bevelled to taper form by using tools such as of cutting, fusion cutting, grindstone, etc. The sizes of bevelling L, H are suitably determined from the relations between the plate width W and plate thickness T of the rolling material 1. As a result, there will be no more tearing at the trailing end of the thin plate rolling material at the time of pass-through of rolling and no more chances for giving recessed flaws to rolls, thus the rolled materil free from any flaws on the surface is produced.
