Compact, flexible csp installation for continuous, semi-continuous and batch operation

Abstract

The invention relates to a compact, flexible CSP installation ( 1,101,201,301,401 ) for endless, semi-endless and batch operation with a casting machine, a roughing stand group ( 7,111,211 ) and a finishing stand group ( 12,118,218 ), wherein for the batch operation or the semi-endless operation, a coil store ( 8,113,213,501 ) is integrated into the roll table, which stores the pre-strip or slab coming from the roughing stand, with the coil store being deactivated in the case of endless operation. The coil store ( 8,113,213,501 ) is designed for an increased holding quantity of pre-strips or slabs such that two, three or more pre-strips or slabs can be wound to jumbo coils on a coil.

         6 . The CSP installation according to  claim 1 ,
 characterized in that   with a deactivated coil store ( 8 , 113 , 213 , 501 ) a roll table covering is used for better thermal insulation of the roll table.   
     
     
         7 . The CSP installation according to  claim 1 ,
 characterized in that   the winding of the jumbo coils takes place in a coil box or winding furnaces.   
     
     
         8 . The CSP installation according to  claim 1 ,
 characterized in that   the production of jumbo coils takes place preferably during an interruption of rolling in the finishing train.   
     
     
         9 . The CSP installation according to  claim 1 ,
 characterized in that   the jumbo coils are removed from the rolling line for intermediate storage, are stored intermediately in a coil furnace and/or if applicable are later delivered to the rolling process again.   
     
     
         10 . The CSP installation according to  claim 1 ,
 characterized in that   depending on the casting speed, the installation is operated in endless mode, semi-endless mode or batch operation.   
     
     
         11 . The CSP installation according to  claim 1 ,
 characterized in that   before or/and behind the coil store, a heating of the pre-strip or slab takes place.   
     
     
         12 . The CSP installation according to  claim 1 ,
 characterized in that   the heating of the pre-strip or slab preferably takes place inductively.   
     
     
         13 . The CSP installation according to  claim 1 ,
 characterized in that   the supply of energy of the heating arrangement is carried out depending on the measured or calculated pre-strip temperature such that as constant a pre-strip temperature as possible occurs over the length behind the heating unit before the finishing stand group.   
     
     
         14 . The CSP installation according to  claim 1 ,
 characterized in that   with the induction heating arrangement, provision is made if required to set higher temperatures before the finishing stand group than the casting machine outlet temperature.
