Casting roll that can be influenced by the profile for casting metal strip in a casting roll system

摘要

The invention relates to a casting roller for the casting of metal strip in the casting gap between two parallel casting rollers with variable separation and which may be cooled. A shaft (1) with a shell (2), surrounding the above at a separation therefrom and an external cover (3), the circumferential surface of which may be adjusted with regard to the crowning thereof during the casting operation, for altering the shape of the external cover, are disclosed. Annular pressure chambers (3c) are thus formed on the inner side of the shell (2) for hydraulically pumping the above up, which are formed between the shells and applied strips (13). The casting roller further comprises means for connecting the annular pressure chambers (3c) to an external hydraulic pressure generating system.
