Abstract

PURPOSE:To prevent the growth of a fish tail in hot rolling by pressing the end of a rolling material in the longitudinal direction, by a die having a formed recessing part, from the axial direction of the material and forming the whole outer peripheral part of the end face of material and a projecting part at the end of material. CONSTITUTION:In forming projecting parts at both ends of a rolling material 1; the material 1 heated to a prescribed temperature is transferred to a turn table 8 by rolls 7, and the turn table 8 is turned to place both end faces of material 1 oppositely to dies 5 having formed recessing parts, and the dies 5 are passed against the end faces 2 of material 1 by presses 6 to form the end faces 2 simultaneously. Then the rolling material 1 having projecting parts 3 formed at its both ends is hot rolled by rolling rolls 9. In this way, the generation of fish tails formed at the ends of rolling material is prevented, and crop loss is reduced and rolling yield is improved.
