Abstract

The invention relates to a device ( 1 ) and a method for laterally guiding a slab ( 2 ) on a transport track ( 3 ), comprising a first guide rule ( 4 ) and a second guide rule ( 5 ). The guide rules ( 4, 5 ) are arranged opposite each other on both sides of the transport track ( 3 ) and are each connected to at least one actuating drive ( 6 ) so as to move in a direction of a width of the transport track ( 3 ). The actuating drive can be actuated perpendicularly to the transport direction ( 7 ) of the slab ( 2 ), wherein the respective longitudinal axis ( 4 L , 5 L ) of the first guide rule ( 4 ) and/or the second guide rule ( 5 ) can be positioned at a specified angle (α) relative to the transport direction ( 7 ) of the slab ( 2 ). The first and/or the second guide rule ( 4, 5 ) has at least one contact roller ( 8 ) which can be brought into contact with a lateral edge of the slab ( 2 ) in order to guide and/or compress the slab ( 2 ).

wherein the first guide rule ( 4 ) and/or the second guide rule ( 5 ) each has at least one contact roller ( 8 ), which can be placed in contact with a lateral edge of the rolled or cast product ( 2 ) by moving the corresponding guide rule ( 4 , 5 ), in order to guide the rolled or cast product ( 2 ) and/or to reduce the width thereof by compression, and
wherein the first guide rule ( 4 , 5 ) and/or the second guide rule ( 4 , 5 ) each has a further contact roller ( 8 ), and the at least one and further contact rollers ( 8 ) are each mounted at an infeed-side end ( 9 ) and at an outlet-side end ( 10 ) of the corresponding guide rule ( 4 , 5 ), respectively.

2. The device ( 1 ) according to claim 1 , characterized in that the at least one contact roller ( 8 ) mounted on the first and/or on the second guide rule ( 4 , 5 ) can be mounted in a center region ( 4 M , 5 M ) thereof instead of being mounted at the infeed side end ( 9 ) thereof.

3. The device ( 1 ) according to claim 1 , characterized in that the first guide rule ( 4 ) and/or the second guide rule ( 5 ) are each connected via an articulated connection ( 11 ) to the respective associated actuating drives ( 6 ).

4. The device ( 1 ) according to claim 3 , characterized in that the respective associated actuation drive is formed as a servo motor for rotational movement of the guide rule ( 4 , 5 ) and is provided in a region of the respective articulated connection ( 11 ), so that the respective longitudinal axis ( 4 L , 5 L ) of the guide rule ( 4 , 5 ) can be positioned at the respective specified angle (α) relative to the transport direction ( 7 ) of the rolled or cast product ( 2 ).

5. The device ( 1 ) according to claim 1 , characterized in that, for the first guide rule ( 4 ) and/or for the second guide rule ( 5 ), a further actuating drive ( 6 ) is provided in each case, which is connected in an articulated manner ( 11 ) to the respective guide rule ( 4 , 5 ), the at least one and the further actuating drives of the guide rules ( 4 , 5 ) are arranged, respectively spaced from one another, and both can be actuated independently of one another, and in that an articulated connection ( 11 ) of at least one of these two actuating drives ( 6 ) is arranged coaxially with the respective guide rule ( 4 , 5 ) or adjacent to an axis ( 12 ) of a respective contact roller ( 8 ) mounted on the respective guide rule ( 4 , 5 ).

6. The device ( 1 ) according to claim 5 , characterized in that each of the articulated connections ( 11 ) of the two actuating drives ( 6 ) is arranged coaxially with the guide rule or adjacent to the axis ( 12 ) of the contact roller ( 8 ) mounted at the infeed-side end ( 9 ) of the guide rule or the contact roller ( 8 ) mounted at the outlet-side end ( 10 ) of the guide rule ( 4 , 5 ).

7. The device ( 1 ) according to claim 5 , characterized in that at least one of the respective two actuating drives ( 6 ) is connected on its side that is opposite the respective guide rule ( 4 , 5 ) to a frame ( 13 ) via a pivotable bearing ( 14 ), wherein the respective guide rule ( 4 , 5 ) is connected in an articulated manner to a respective sliding guide ( 15 ) which can be displaced perpendicularly to the transport direction ( 7 ) of the rolled or cast product ( 2 ), such that another of the two actuating drives ( 6 ) is operatively connected to the sliding guide ( 15 ).

8. The device ( 1 ) according to claim 7 , characterized in that the articulated connection ( 11 ) is provided at a center region ( 4 M , 5 M ) of the first and/or second guide rule ( 4 , 5 ), or in that the articulated connection ( 11 ) of the sliding guide ( 15 ) to the guide rule ( 4 , 5 ) is provided in the region of the infeed-side end or the outlet-side end ( 9 , 10 ) thereof, and is arranged coaxially or adjacent to an axis ( 12 ) of a contact roller ( 8 ) mounted at a same point on the guide rule.

9. The device ( 1 ) according to claim 1 , characterized in that the actuating drives ( 6 ) can be actuated in a force-controlled manner by means of a pressure transducer ( 17 ) and/or in a path-controlled manner by means of a path transducer ( 18 ).
