However, in the conventional spindle coupling device 7 as described above, since there is a gap S between the neck portion 2a of the work roll 2 and the concave portion 8a of the yoke 8, the liner 9 is formed. Wear becomes severe due to repeated impacts during operation of the rolling mill. When the degree of this wear progresses, the vibration of the spindle coupling device 7 increases, and the vibration causes rattling in the rotation of the work roll 2. Then, the vibration affects the rolled material and causes quality defects called so-called chatter marks. Therefore, it is important to control the wear of the liner 9,
Therefore, there is a problem that frequent replacement is required.

[Operation] According to the present invention, when the rolling mill is in operation, the gap S between the neck of the work roll and the recess of the yoke can be reduced to 0 by cooling the yoke with the cooling medium. Therefore, the vibration of the spindle coupling device does not occur, and thus the progression of wear of the liner can be suppressed. Further, when the work roll is replaced, the yoke S is heated and thermally expanded by the heating medium, so that the gap S between the neck of the work roll and the recess of the yoke can be increased. It can be done promptly.

The gap S between the neck portions 2a of the work rolls 2 was manufactured to be 0 mm at room temperature 25 ° C. Further, the diameter of the perforations 10 inside the yoke 8 was 15 mmφ, and they were arranged in a serpentine shape at a pitch of 100 mm on the entire surface. In addition, 150 ° C. steam was used as the heating medium, and room temperature water (25 ° C.) was used as the cooling medium.

When the yoke 8 is heated, if the neck portion 2a of the work roll 2 is also heated, the required gap S cannot be obtained. Therefore, the work roll is quickly extracted after the steam is introduced, or the yoke 8 is removed. It is desirable that the inner surface of the concave portion 8a be subjected to, for example, insulating thermal spraying of Al 2 O 3 or the like to prevent heat of the yoke 8 from flowing to the neck portion 2a.
