Abstract

A cluster mill housing applicable to 20-high and 12-high cluster mills. The mill housing is similar in size and form to a comparable monobloc housing but is made of four distinct parts. The first part is a floor portion having a central lower roll cavity containing part terminating in end members and having a vertical column at each of its four corners. The second part comprises a roof portion having a central upper roll cavity containing part terminating at each of its ends in ears. The third and fourth parts comprise substantially identical bridge members overlying the roof portion ears and having downturned ends affixed to the tops of the columns. Each of the bridge members contain adjustment screws which bear against the adjacent roof portion ear. A synchronized drive assembly rotates the four adjustment screws equally and in the same direction to adjust the vertical position of the roof portion with respect to the floor portion. Hydraulic counterbalance assemblies are affixed to the bridge members and are connected to the roof portion to support the weight of the roof portion and to maintain the roof portion against the four adjustment screws.
