Abstract

PURPOSE:To reduce a crop loss at the end of a rolling sheet-material and to improve its rolling yield by setting the width rolling reduction at a slab-biting part larger than a prescribed one to roll the slab reversingly in reversing rolling the slab width by a vertical mill having vertical rolls with calibers. CONSTITUTION:In rolling a slab in the width direction by using vertical rolls 4, 6 with calibers, the fixed length of a slab biting part is rolled under a rolling reduction larger than a prescribed one, and then the slab is reversingly rolled under the prescribed rolling reduction. When the slab is reversely rolled, the formation of a fish tail is remarkably reduced by the rolling conjointly with the effect of the caliber part. Therefore the crop loss of the slab is reduced and its rolling yield is improved.
