Abstract (en)
[origin: US7111486B2] The invention relates to a roll stand for hot-rolling or cold-rolling metallic strips. The roll stand comprises back-up rolls and work rolls ( 2, 3; 4, 5 ) which are respectively positioned in chocks ( 6; 7 ) in a rotating manner. Each chock ( 6; 7 ) can be displaced on two sides in guiding devices ( 8 ) of the column frame ( 9 ) for adjusting the roll gap ( 10 ) and can be additionally displaced on at least one side for adjusting the play, by means of horizontal piston cylinder units ( 11 ) arranged in the column frame ( 9 ). The aim of the invention is to completely eliminate the play in the vertical guiding device ( 8 ) of the work roll chocks ( 6; 7 ) during the rolling. To this end, the chocks which are guided on at least one side of the 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 side of the piston ( 11 a), can be pressed against the other side of the column ( 9 b) and the guiding device ( 8 ) thereof without play when the vertical roll positioning drive is stopped. and can be released when the vertical roll positioning device is switched on.
