Title:
ROLLING MILL FACILITY
Document Type and Number:
Japanese Patent JPS5791802
Kind Code:
A
Abstract:

PURPOSE: To lower facility cost and to maintain high quality and productivity by supporting work rolls with ≥1 piece of work rolls, disposing the same in such a way as to create roll bites between the upper and lower work rolls, and providing screw down devices to upper and lower backup roll housings.

CONSTITUTION: This rolling plant is constituted of upper work rolls T1WT3, lower work rolls B1WB4, lower backup roll housings LT1WLT5 and upper backup roll housings LB1WLB4 incorporated with screw down devices, upper backup rolls L1WL3, and lower backup rolls B1WB4. More specifically, the rolls T1WT3 and the rolls B1WB3 are supported to the roll housings in such a way that they are driven respectively independently, and the backup rolls of small diameters are supported at both end parts by the arc-shaped gages mounted to the roll housings. Hence, if the work rolls are driven, the backup rolls rotate, and roll bites A1WA3 are created by the screw down devices.
