A rolling mill includes paired upper and lower work rolls (2) for rolling a strip (1) , paired upper and lower intermediate rolls (3) for supporting the paired upper and lower work rolls, and paired upper and lower back-up rolls (4) for supporting the paired upper and lower intermediate rolls. In the rolling mill, the paired upper and lower work rolls (2) each have two bearing housings (13a, 13e, 13b, 13f, 13c, 13g, 13d, 13h) mounted on each side, and the bearings are restrained in the horizontal direction by backlash elimination cylinders (18a, 18e, 18b, 18f, 18c, 18g, 18d, 18h). The work rolls have a small diameter, and use a material having a high modulus of longitudinal elasticity, such as a cemented carbide or a ceramic. |
