ROLLING MILL LOOSENESS ELIMINATING DEVICE OF ROLL BEARING HOUSING ROLLING METHOD METHOD OF MODIFYING ROLLING MILL AND HOT FINISHING TANDEM ROLLING EQUIPMENT

摘要

The present invention relates to a rolling mill, a roll bearing box shake removing apparatus, a rolling method, a rolling mill modifying method, and a hot finishing tandem rolling mill, comprising: a roll bearing box rotatably supporting a rolling roll in a housing; And a second pressing device for applying a pressing force in a direction orthogonal to the rolling roll axis in a horizontal plane to the roll bearing box is provided on the rolling roll, And the first pressing device and the second pressing device are disposed so as to be shifted in the rolling roll axis direction. Alternatively, the second pressing device is disposed between the plurality of first pressing devices in the direction of the rolling roll axis.;And, it is possible to eliminate the shaking of the roll bearing box of the rolling mill without enlarging the facility.
