Abstract
PURPOSE: To restrict the increase of the amount of the crop even if the breadthways rolling reduction increases, and also, to contrive the improvement of the yield, by forming either one of forefront or tail end of the slab into a tapered shape in respect of the breadthways rolling reduction, at the titled rolling method by the vertical and horizontal rolls.
CONSTITUTION: At the titled rolling method in which the slab is subjected to the edging pass in the direction of the breadth by the vertical roll and to the flat rolling pass in the direction of the thickness by the horizontal roll, the plane shape of said slab F is formed into a tapered shape in at least one of its forefront or tail end. That is, when this taper forming depth m1 in the direction of the breadth is made smaller than the taper forming length l1 in the longitudinal direction, and the breadthways rolling reduction is taken as ΔW, these values are selected so as to satisfy the formula I; meanwhile, when the taper forming depth m2 in the direction of breadth is made larger than the taper forming length l2 in the longitudinal direction, and the breadthways rolling reduction is taken as ΔW, these values are selected so as to satisfy the formula II; after finishing these adjustments, said rolling work is carried out. Hereby, the amount of the crop is reduced and the yield is improved.
