Roll stand with back-up rolls and/or work rolls for rolling sheet metal or strips
View Patent ↗The invention concerns a rolling stand ( 1 ) with backup rolls and/or work rolls ( 2, 3, 4, 5 ) for rolling plate ( 6 ) or strip, with at least one rest bar ( 8 ), which is arranged between the work roll chocks ( 7 ) and preferably is assigned to the upper roll ( 3 ); with an inlet/outlet guide ( 9 ) for a medium, e.g., cooling water or the like, arranged next to the rest bar ( 8 ); and with sealing means ( 10 ) for preventing the medium, e.g., cooling water, from dripping onto the rolling stock. In accordance with the invention, it is provided that the sealing means ( 10 ) for preventing the medium, e.g., cooling water, from dripping onto the rolling stock is designed as at least one sealing strip ( 11 ) arranged between the rest bar ( 8 ) and the inlet/outlet guide ( 9 ).
1. A rolling stand ( 1 ), comprising:
backup rolls and/or work rolls ( 2 , 3 , 4 , 5 ) for rolling plate ( 6 ) or strip, with at least one rest bar ( 8 ), which is arranged between chocks ( 7 ) of one of the rolls and preferably is assigned to the upper roll ( 3 );
an inlet/outlet guide ( 9 ) for a cooling medium arranged next to the rest bar ( 8 );
and sealing means ( 10 ) for preventing the medium from dripping down onto the rolling stock, wherein the sealing means ( 10 ) for preventing the medium from dripping down is designed as at least one sealing strip ( 11 ) arranged between a downwardly-facing, substantially horizontal surface of the rest bar ( 8 ) and an upwardly-facing, substantially horizontal surface of the inlet/outlet guide ( 9 ).
2. A rolling stand in accordance with claim 1 , wherein the sealing strip ( 11 ) is mounted in a mounting groove ( 12 ) located in the area between the rest bar ( 8 ) and the inlet/outlet guide ( 9 ).
3. A rolling stand in accordance with claim 2 , wherein the sealing strip ( 11 ) is supported in the mounting groove ( 12 ) in a pretensioned state.
4. A rolling stand in accordance with claim 3 , wherein at least one spring mechanism ( 13 ) is provided for pretensioning the sealing strip ( 11 ) in the mounting groove ( 12 ).
5. A rolling stand in accordance with claim 3 , wherein a pneumatic system is provided for pretensioning the sealing strip ( 11 ) in the mounting groove ( 12 ).
6. A rolling stand in accordance with claim 3 , wherein a hydraulic system is provided for pretensioning the sealing strip ( 11 ) in the mounting groove ( 12 ).
7. A rolling stand in accordance with claim 2 , wherein the arrangement of the sealing strip ( 11 ) in the mounting groove ( 12 ) includes a retaining device ( 14 ) for the sealing strip ( 11 ).
8. A rolling stand in accordance with claim 7 , wherein the retaining device ( 14 ) for the sealing strip ( 11 ) mounted in the mounting groove ( 12 ) takes the form of at least one screw ( 15 ).
