Abstract:
1. Rolling device ( 1 ) with at least two work rolls ( 2 , 3 ), each of which is supported by a work roll chock ( 4 , 5 ) in a rolling stand ( 6 ), wherein at least one of the work rolls ( 2 , 3 ) in the rolling stand ( 6 ) can be adjusted, especially in the vertical direction, for the purpose of adjusting a desired roll gap relative to the other work roll ( 2 , 3 ), wherein at least one work roll ( 2 , 3 ) is operatively connected with bending devices ( 7 ), by which a bending moment can act on the work roll ( 2 , 3 ), and wherein the work roll chock ( 4 , 5 ) has arms ( 9 , 10 ) that project laterally relative to the axis ( 8 ) of the work roll ( 2 , 3 ) for absorbing the force produced by the bending devices ( 7 ), wherein a pressure-transmitting element ( 12 ), which can be shifted relative to the rolling stand ( 6 ), especially in the vertical direction, is installed between an element ( 11 ) of the bending devices ( 7 ) that generates compressive force, especially a piston, and the projecting arm ( 9 , 10 ) of the work roll chock ( 4 , 5 ), such that the element ( 11 ) of the bending devices ( 7 ) that generates compressive force and the projecting arm ( 9 , 10 ) of the work roll chock ( 4 , 5 ) are positioned in such a way that the center axis ( 13 ) of the element ( 11 ) that generates compressive force intersects the projecting arm ( 9 , 10 ), such that the bending devices ( 7 ) are mounted in a block ( 16 ) rigidly mounted on the rolling stand ( 6 ), and the pressure-transmitting element ( 12 ) is supported on the block ( 16 ) by means of a guide ( 17 ), especially a vertical guide, and such that the pressure-transmitting element ( 12 ) has a U-shaped horizontal cross section and surrounds the block ( 16 ), at least partially, on three sides, and the pressure-transmitting element ( 12 ) has an L-shaped vertical cross section perpendicular to the axis ( 8 ) of the work roll ( 2 , 3 ) and at least partially surrounds the upper side of the block ( 16 ), wherein the pressure-transmitting element ( 12 ) is supported directly on the rolling stand ( 6 ) by a vertical guide ( 18 ) provided on the rolling stand.
