Abstract
PURPOSE:To reduce the wear of a horizontal roll and to extend the service life of a roll by specifying the taper angle of the horizontal roll of an intermediate rough universal rolling mill and arranging a straightening stage in a rolling device line. CONSTITUTION:The taper angle theta of the horizontal rolls 34a, 34b used in an intermediate rough universal rolling mill is formed in the range of 10 deg.-25 deg. and the outer face of vertical rolls 33a, 33b is also formed at about the same angle as said taper angle. The flange straightening stage 5 for standing the flange taper angle theta formed on the material 1d to be rolled is provided between the final stage rolling mill 3b of the intermediate rolling mill and a finishing universal rolling mill 4. Consequently the wear of roll is reduced and the roll consumption unit is improved.
