Abstract
A rolling mill having an upper set of rolls which has a work roll and a backup roll, and a lower set of rolls which has a work roll and a backup roll. Two parallel intermediate rolls are arranged between the work roll and the backup roll of either upper set or lower set or both sets, each of the intermediate rolls being supported by corresponding support rolls. The support rolls can be shifted toward and away from the corresponding intermediate rolls.
Claims12
A rolling mill comprising an upper and a lower set of rolls, at least one of said sets comprising a work roll, a backup roll for receiving vertical forces imposed upon said set of rolls, two parallel intermediate rolls arranged between the work roll and the backup roll, at least one support roll adjacent each intermediate roll, said intermediate rolls and support rolls having axes lying substantially within a common horizontal plane, the backup roll having a diameter greater than a diameter of the support rolls, the diameter of the support rolls being less than a diameter of the intermediate rolls, and means operatively connected to said support rolls for controllably shifting each support roll horizontally toward and away from the respective intermediate roll to thereby adjust the horizontal bend of each intermediate roll.
