Abstract
An installation for replacing live rolls in a rolling mill, comprising a drum which rotates about an axis parallel to the axes of the rolls in the tightening plane passing through these axes. The drum comprises at least two compartments, each symmetrical with respect to a median plane passing through the axis of rotation, and which can be placed, alternately, by rotating the drum, in a roll replacement position in front of the working zone of the mill stand. Each compartment has two pairs of guide rails which, in the roll replacement position of the corresponding compartment, are aligned, respectively, with two pairs of fixed rails in the stand. One of the compartments is vacant, while each of the other compartments holds in store a pair of live rolls, which have chocks bearing on the corresponding rails of the compartment. The drum is associated with a mechanism for transferring live rolls into the vacant compartment of the drum and replacement rolls into the working position in the stand.
