ABSTRACT:
In roll housings for rolling mills, it is desirable to be able to separate the top and bottom halves of the housing so as to be able to change the rolls. When the top and bottom halves are reassembled, they must be held firmly together to ensure correct operation of the rolling mill. It is proposed to have hydraulically-tensionable tie bars which are fixed in the lower half of the housing, and which grip the top of the upper half of the housing. Hydraulic fluid is applied to produce the tension, and the fluid pressure achieved is maintained throughout rolling operation. Such tie bars will normally be provided at at least four corners of a roll housing, and a single hydraulic circuit will supply fluid to all the bars. In addition, hydraulically operated jacks can be used to pivot the tie bars into and out of position, and these jacks can be operated from the same hydraulic circuit.
