EQUIPMENT AND METHOD FOR TANDEM ROLLING

摘要

PURPOSE: To realize stable rolling by suppressing the deflection of work rolls and without making the bearing boxes of the work rolls flactuate in tandem rolling equipment and its rolling method. CONSTITUTION: The axial center of the work roll 1 is offset on the opposite side of a side where tension added to the inlet side and the outlet side of a rolled stock 10 is larger to the axial center of an intermediate roll 2 and a hydraulic cylinder 11 for pressing the bearing box 4 of the work roll against the same side as the offsetting direction is incorporated in a block 8.
