PURPOSE:To make high draft rolling possible with a relatively compact mill by arranging backup rolls to the upper and lower work rolls disposed in a leveler shape, and screwing down these with the screw-down devices provided to upper, lower backup roll housings. CONSTITUTION:Plural upper work rolls T1-T5 and lower work rolls B1-B5 arranged at constant inervals are so supported to roll housings as to be driven respectively independently. The respective upper and lower work rolls T1-T5, B1-B5 are supported at both ends with the arc-shaped cages mounted with backup rolls L1-L5, L11-L14 of small diameters around said rolls to brackup roll housings LT1-LT5, LB1-LB5. When the rolls T1-T5, B1-B5 are driven, the rolls L1-L5, L11-L14 rotate, and roll bites A1-A8 are formed by the screw- down devices installed to the rolls L1-L5, L11-L14. |
