Strand guide, in particular for a continuous steel slab casting installation

Abstract

The present invention relates to a strand guide ( 1 ), in particular for a steel slab continuous casting installation, comprising a number of segments ( 2 ) that support a strand on two opposite sides ( 4, 5 ) thereof with support elements ( 6, 7 ), wherein the support elements ( 6, 7 ) are arranged in at least one lower frame ( 8 ) and at least one upper frame ( 9 ) for guiding the strand ( 3 ) in a conveying direction, and wherein the frames ( 8, 9 ) are arranged on at least one central bar ( 10 ). In order to facilitate exchange of segments or their parts, according to the intention there is available means ( 11 ) with which the at least one upper and/or at least one lower frame ( 8, 9 ) can be adjusted relative to the at least one central bar ( 10 ) in a conveying direction (F) or in opposite direction.

1 . A strand guide ( 1 ), in particular for a steel slab continuous casting installation, comprising a number of segments ( 2 ) that support a strand on two opposite sides ( 4 ,  5 ) thereof with support elements ( 6 ,  7 ), wherein the support elements ( 6 ,  7 ) are arranged in at least one lower frame ( 8 ) and at least one upper frame ( 9 ) for guiding the strand ( 3 ) in a conveying direction, and wherein the frames ( 8 ,  9 ) are arranged on at least one central bar ( 10 ),
 characterized in that   there is available means ( 11 ) with which the at least one upper and/or at least one lower frame ( 8 ,  9 ) can be adjusted relative to the at least one central bar ( 10 ) in a conveying direction (F) or in opposite direction.   
     
     
         2 . A strand guide according to  claim 1 ,
 characterized in that   a central bar ( 10 ) is provided as each side of a segment ( 2 ).   
     
     
         3 . A strand guide according to  claim 1 ,
 characterized in that   the segments ( 2 ) form a casting bow.   
     
     
         4 . A strand guide according to  claim 1 ,
 characterized in that   the means ( 11 ) comprises at least one actuator ( 12 ) that can displace one of the frames ( 8 ) in the conveying direction (F) relative to the central bar ( 10 ).   
     
     
         5 . A strand guide according to  claim 4 ,
 characterized in that   the actuator ( 12 ) is formed as a double-action piston-cylinder unit.   
     
     
         6 . A strand guide according to  claim 4 ,
 characterized in that   the actuator ( 12 ) comprises two piston-cylinder units arranged on the central bar ( 10 ).   
     
     
         7 . A strand guide according to  claim 4 ,
 characterized in that   the actuator ( 12 ) is formed as a hydraulic piston-cylinder system.   
     
     
         8 . A strand guide according to  claim 4 ,
 characterized in that   the actuator ( 12 ) is formed as a pneumatic piston-cylinder system.   
     
     
         9 . A strand guide according to  claim 4 ,
 characterized in that   the actuator ( 12 ) is formed as a mechanical longitudinally adjusting element.   
     
     
         10 . A strand guide according to  claim 9 ,
 characterized in that   the actuator ( 12 ) comprises an electric motor-driven threaded spindle system.   
     
     
         11 . A strand guide according to  claim 1 ,
 characterized in that   the support elements ( 6 ,  7 ) are formed as driven or non-driven rollers rotatably supported in the frames ( 8 ,  9 ).
