Abstract (en)

[origin: WO2004050271A1] The invention relates to a rolling mill (1) comprising several rolling frames (Fi) and support plates (7) that are provided on the operator side (BS) of the frames (Fi) and can be displaced transversally to the roll axes, said plates being equipped to receive sets of working rolls (14) and lying adjacent to the mill floor (9). The mill also comprises pits (8) that are situated on the operator side (BS) upstream of each frame (Fi), the bottom of said pits being configured to deploy sets of support rolls (12). The aim of the invention is to reduce the time required to exchange the rolls. To achieve this: the support plates (7) are arranged in a support plate line (6), directly adjacent to the rolling frames (Fi) and covering the pits (8); the support plates (7) are detachably interconnected and in order to exchange the set of support rolls (12), the support plate line (6) can be displaced out of the frame area (5) transversally to the roll axes along the line of the pits, in subgroups (17) of interconnected support plates or in its entirety (6 ), in order to open at least one and if required all pits (8).
