Abstract
PURPOSE:To improve the dimensional accuracy by correcting the shape of a rolled stock after rolling by facing rolling rolls by use of equally arranged correction rolls and by applying a sufficient pressure which reduces dimensional variations of the stock and then finishing rolling the stock by orthogonally installed and faced finishing rolls. CONSTITUTION:The shape of a rolled stock is corrected by facing correction rolls 8 installed between faced finishing rolls 6 and faced rolling rolls 7 installed in the upstream side of the rolls 6 by applying sufficient pressure on the rolls 8. Then, the rolls 6 installed orthogonally to the rolls 8 perform finishing rolling. By this method, dimensional deviations are reduced to improve the dimensional accuracy.
