Abstract
A multistage rolling mill includes: four columns 12a, 12b, 12c, and 12d linking, in an up-down direction, four corners of each of an upper mill housing 8, a lower mill housing 9, and a base mill housing 10; a press-down section that is provided on an upper side of the four columns 12a, 12b, 12c, and 12d in a vertical direction and that is capable of raising and lowering the upper mill housing 8; and a lower mill housing spacer that is provided between the lower mill housing 9 and the base mill housing 10 and that adjusts the position of the lower mill housing 9 in the vertical direction. With this configuration, a compact multistage rolling mill with a smaller installation space than a conventional cluster-type rolling mill is provided.
