Patent ID: 7111486

Claim:
Rolling stand for the hot rolling or cold rolling of metallic strip material with backup rolls and work rolls, each of which is pivoted in chocks, such that each chock can be displaced on two sides in guiding devices of a column frame for adjusting the roll gap and can be additionally displaced on at least one side for adjusting the play by means of horizontal piston-cylinder units arranged in the column frames, wherein the work roll chocks ( 6 ; 7 ), which are guided on at least one side of a column ( 9 a ) by means of the piston-cylinder unit ( 11 ) arranged in the column frame ( 9 ) and by means of one respective support element ( 14 ), which is arranged on the front end ( 11 a ) of the piston, can be pressed against the other side of the column ( 9 b ) and its guiding device ( 8 ) without play, when a vertical roll positioning drive is stopped, and can be released, when the vertical roll positioning drive is turned on, wherein, in connection with a bending cylinder ( 25 ) that acts on a roll neck ( 4 a; 5 a ) and runs perpendicularly to the roll axis ( 24 ), several individual piston-cylinder units ( 27 ), which are arranged at some distance ( 26 ) from the bending cylinder ( 25 ), act on a piston head ( 11 b ), wherein the hydraulic pressure in the piston-cylinder unit ( 11 ) can be regulated to different pressures for play adjustment or play elimination for the chock ( 6 ; 7 ) in the guiding device ( 8 ) of the given side of the column ( 9 a ; 9 b ), and that, for a vertical displacement of the chocks ( 6 ; 7 ), a control can be switched to signals of an automatic gage control (AGC).
