摘要： The present invention relates to a rolling mill, a gap-removing apparatus for roll bearing boxes, a rolling method, a modifying method for a rolling mill, and hot finish tandem rolling equipment, and is characterized in that there are provided roll bearing boxes for rotatably supporting work rolls in a housing, a first pushing device for applying a vertical balancing force or bender force to the work rolls through the roll bearing boxes, and a second pushing device for applying a pushing force in a direction orthogonal to the work roll axis in a horizontal plane to the roll bearing boxes, and the first pushing device and the second pushing device are disposed to be offset from each other in the work roll axis direction. Alternatively, the invention is characterized in that the second pushing device is disposed between a plurality of the first pushing device in the work roll axis direction. Gaps at the roll bearing boxes in the rolling mill can be removed without enlarging the equipment in size.
