Abstract
Compensation device for chocks in four-high rolling mill stands (13) with pair crossing of the rolls (12,112,14,114), the device (10) cooperating with the opposed sides of at least one chock (11) of at least one back-up roll (12, 14), the rolling mill stand (13) comprising a stationary housing (16) and means (21) to transmit a load force ('P') acting substantially on the longitudinal median plane of the stand (13) and contrasting the force of thrust ('S'), the transmission means (21) being located between the stationary housing (16) and the relative chock (11), the rolls (12, 14) including at least a crossover position wherein the load force ('P') defines an eccentricity ('e') with respect to the force of thrust ('S'), the device comprising actuator means (15,115) associated with at least one face of at least one chock (11) and exerting on the chock (11) a push-and-pull action associated functionally with the actual crossover position of the relative roll (12) in relation to the longitudinal median plane passing through the center line of the rolling mill stand (13) and/or functionally associated with the value of the eccentricity ('e').
