Rolling mill for rolling metallic material
View Patent ↗A rolling mill ( 1 ) for rolling a metal workpiece ( 2 ) that is provided with at least one roll stand ( 3 ) as well as with a conveyor ( 4 ) for the material to be rolled ( 2 ) extending on both sides of the roll stand ( 3 ) for a predetermined length (L) is based on the object that in the area of the longitudinal extent of the conveyor ( 4 ) at least one holder ( 5 ) for a coil ( 6 ) of the metal workpiece ( 2 ) is provided that can be positioned in a first position (A) in which it does not disturb the transport of the metal workpiece ( 2 ) along the conveyor ( 4 ) and that can be positioned in a second position (B) in which the coil ( 6 ) is positioned close to the roll stand ( 3 ) on the conveyor ( 4 ) for unwinding or winding up the coil ( 6 ).
1. In a rolling mill for rolling a metal workpiece and provided with at least one roll stand and with a conveyor for the workpiece to be rolled and extending longitudinally on both sides of the roll stand over a predetermined length, the improvement comprising:
a holder for a coil of the metal workpiece that can move transversely of the conveyor between a lower first position in which it does not disturb longitudinal transport of the metal workpiece along the conveyor and an upper second position in which the coil is positioned close to the roll stand on the conveyor for unwinding or winding up of the coil;
a lifter for carrying the holder and for vertically moving the holder between the upper and lower positions; and
a driven strip-guiding roller mounted on the lifter.
2. The rolling mill according to claim 1 , wherein the strip-guiding roller is positioned in the lower position of the lifter at the height of other rollers of the conveyor.
3. The rolling mill according to claim 1 , further comprising
one pair of hot edge-trimming shears provided with vertical actuators with which they can be brought into an operating position or out of this operating position.
4. The rolling mill according to claim 1 , further comprising
strip supporting or driving or adjusting means provided with vertical actuators by means of which they can be brought into an operating position or out of the operating position.
5. The rolling mill according to claim 4 wherein the strip supporting or driving or adjusting means are provided with a bridle-roller-assembly with an attached drive.
6. The rolling mill according to claim 1 , further comprising
a counter roller that interacts with the strip-guiding roller that can be vertically positioned at a predetermined height.
7. The rolling mill according to claim 1 , further comprising
means for providing coolants or lubricants to rolls of the roll stand or to the workpiece to be rolled.
