Abstract

PURPOSE:To prevent the occurrence of the buckling and at the same time to increase the rolling reduction per pass, by pressing a material to be rolled with upper and lower pressure rolls at the intermediate part as well as both ends in the width direction of said material. CONSTITUTION:Edge part pressure rolls 4 and 5 are set to the positions close to the inner sides of right and left longitudinal rolls 1 and 2 so as to press a material 3 to be rolled at both ends in the width direction of the material 3 from upper and lower sides. At the same time, intermediate part pressure rolls 10 and 11 are set to upper and lower housings 6 and 7 via roll stands 8 and 9 to support the mateial 3 at the intermediate part in the width direction of the material 3. The upper and lower intervals can be set for each of these pressure rolls 4, 5, 10 and 11 in accordance with the thickness of the material plate 3. As a result, the occurrence of the dog bone due to an edger is prevented by the rolls 4 and 5, and at the same time bucking is also prevented by the effect to extend the material to be rolled in the width direction.
