Embodiment Construction

[0021] As shown in Fig. 1, according to the invention, the roll body section shape is adjusted by liquid pumping of the deformable annular band 13 formed between the sleeve 2 and the radial cavity 3c. The belt 13 deformed by the pressure exerts a force on the cavity 3 c and thus deforms the casting roll sleeve 3 . The radial cavity 3 c supporting the casting roll sleeve 3 can have an undercut at least in regions in order to achieve a more elastic force compensation when adjusting the crown.

[0022] The quick exchangeability of the casting rolls is achieved by means of an annular torque motor 6 mounted on the shaft 1 and a water inlet and outlet through the water clamping plate 14 . The delivery of the oil required to adjust the cross-section of the casting roll sleeve 3 takes place through the shaft 1 opposite the water inlet and outlet 14a, 14b. Accordingly, the connections for the liquid high-pressure medium and the connections for the water input and output are arranged o...

Abstract

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.

Description

technical field [0001] The invention relates to casting rolls for casting metal strips in the casting gap of two cooling parallel casting rolls with variable spacing, which have a shaft and for connecting the pressure piece to a hydraulic external pressurization system The shaft has a radially spaced sleeve surrounding the shaft and an outer roller sleeve whose outer circumference can be adjusted by means of a hydraulic pressure piece during the casting operation. Background technique [0002] Casting rolls are known which are driven by means of a stationary electric motor, transmission and couplings with rotating shafts. A disadvantage of this construction is that the casting rolls can only be changed on one side. For this purpose, the casting rolls must be disconnected from the drive with great difficulty. [0003] Another construction mode is to connect a casting roll shaft with a ring torque motor, which drives the shaft of the casting roll to rotate with its fixed sha...
