Abstract
PURPOSE: To diminish the amount of fish tail to be generated at the top and bottom ends of a material to be rolled, at carrying out an edging pass, by making the cross section of the material to be rolled, keeping a variation of rate of thickness difference larger than a prescribed value, into a domed shape.
CONSTITUTION: A sheet material 1 is rolled by a horizontal rolling mill R1 with work rolls 3, 3' whose diameter at both ends is made larger than that of the middle zone; hereby, the cross section of the sheet material 1 is formed into a domed shape. The material 1 is then subjected to an edging pass carried out by a vertical rolling mill E1 with vertical rolls 2; hereby, the breadth of material 1 is reduced to a prescribed size. The material 1, wherein a fish tail is formed as a result of the said edging pass, is then rolled by the next rolling mill R2 with work rolls 3, 3' keeping a rolling reduction so as to hold the final variation of the rate of thickness difference at ≥0.2; hereby, a sheet material with a small fish tail is obtained.
