ABSTRACT:
Alternative tandem arrangements of rolling mill stands are formed by supporting a plurality of separate and independently operable rolling mill stand assemblies upon one or more pedestals extending along a given passline. In one disclosed embodiment, a single pedestal extends along the passline and includes an angularly-shaped plate extending parallel to the passline and including inclined surfaces for carrying rolling mill assemblies at spaced locations. Auxiliary adapter pedestals are disclosed to position a rolling mill stand such that the rotational axes of its rolls are inclined in a different relation to the horizontal than when the mill stand is supported directly by the angularly-shaped plate on the pedestal. In a second embodiment, a plurality of side-by-side pedestals extend along a passline. Each pedestal defines a separate rolling mill support surface with the support surfaces of adjacent pedestals lying in intersecting support planes. An improved rolling mill stand assembly is disclosed. The mill stand assembly includes a box-like frame with housing plates located in a spaced-apart relation for resisting a separating force developed between a pair of rotating rolls supported thereby. A separate motor and gear drive are supported by the frame of each mill. The housing plates have aligned bores that receive eccentric bushings for adjusting the gap between the rolls. One housing plate is a permanent part of the frame while the other housing plate is attached by bolts to the frame for removal during roll changing.
