Device for Producing a Metal Strip by Continuous Casting

Abstract

The invention relates to a device for producing a metal strip ( 1 ) by continuous casting, using a casting machine ( 2 ) in which a slab ( 3 ), preferably a thin slab, is cast. At least one milling machine ( 4 ) is arranged in the direction of transport (F) of the slab ( 3 ) behind the casting machine ( 2 ), in which at least one surface of the slab ( 3 ), preferably two surfaces which are opposite to each other, can be milled. At least one descaling device ( 5 ) is arranged in the direction of transport (F) of the slab ( 3 ) behind the casting machine ( 2 ). In order to keep the temperature loss during processing and/or machining of the slab to a minimum, the milling machine ( 4 ) and the descaling device are embodied ( 5 ) as an integral unit ( 6 ).

1 . A device for producing a metal strip ( 1 ) by continuous casting with a casting machine ( 2 ) in which a slab ( 3 ) is cast, where at least one milling machine ( 4 ) is installed downstream of the casting machine ( 2 ) in the direction of conveyance (F) of the slab ( 3 ), at least one surface of which can be milled down in the one or more milling machines ( 4 ), and where at least one descaling system ( 5 ) is installed downstream of the casting machine ( 2 ) in the direction of conveyance (F) of the slab ( 3 ), wherein the milling machine ( 4 ) and the descaling system ( 5 ) are constructed as an integral unit ( 6 ) by installing the milling machine ( 4 ) and the descaling system ( 5 ) in a common housing ( 7 ). 
     
     
         2 . A device in accordance with  claim 1 , wherein the milling machine ( 4 ) comprises two milling cutters ( 8 ,  9 ). 
     
     
         3 . A device in accordance with  claim 1 , wherein the descaling system ( 5 ) comprises high-pressure nozzles ( 10 ) for descaling fluid. 
     
     
         4 . A device in accordance with  claim 3 , wherein a plurality of high-pressure nozzles ( 10 ) is arranged in the milling and descaling unit ( 6 ) in the direction of conveyance (F). 
     
     
         5 . A device in accordance with  claim 1 , wherein a furnace ( 11 ) is installed upstream of the milling and descaling unit ( 6 ) with respect to the direction of conveyance (F). 
     
     
         6 . A device in accordance with  claim 1 , wherein one milling cutter ( 8 ,  9 ) each is installed for machining the upper side and the underside of the slab ( 3 ). 
     
     
         7 . A device in accordance with  claim 6 , wherein the two milling cutters ( 8 ,  9 ) are installed some distance apart in the direction of conveyance (F). 
     
     
         8 . A device in accordance with  claim 7 , wherein each milling cutter ( 8 ,  9 ) cooperates with a support roll ( 12 ) arranged on the other side of the slab ( 3 ). 
     
     
         9 . A device in accordance with  claim 1 , wherein a rolling stand or a rolling train ( 13 ,  14 ) is installed downstream of the milling and descaling unit ( 6 ) with respect to the direction of conveyance (F). 
     
     
         10 . A device in accordance with  claim 1 , wherein it is designed in such a way that the descaling system ( 6 ) and the milling machine ( 4 ) can be alternatively used at one's option. 
     
     
         11 . A device in accordance with  claim 1 , wherein it is designed in such a way that the descaling system ( 6 ) and the milling machine ( 4 ) can be operated at the same time.
