FIELD: metallurgy.
SUBSTANCE: invention considers devices for working rolls levelling in rolling line, particularly, in four-roll rolling mills by means of, at least, one pair of bushes acting upon roll pads between parallel and distanced racks of rolling mill framework. The device bushes are located so that they can move in horizontal slide plane with regard to the framework racks due to toggle lever adjustment. For this purpose, the pair bushes are interconnected with solid interval. In order to shift both bushes, a special assembly built up from two toggle levers is provided. One lever thereof rests upon the bush through a single joint, while the other rests upon the opposite rack of the shoe through the other joint. Both levers are interconnected by means of the toggle lever joint being moved in longitudinal direction.
EFFECT: reduced time for stand positioning in working position, precise adjustment of rolls, reduced dimensions and simplified structure.
