Description

Technical Field

[0001] The utility model relates to the technical field of metal continuous casting, in particular to an integral clamping roller for a wide slab continuous casting sector. Background Art

[0002] When the section width of the slab continuous casting machine exceeds 1500mm, in order to prevent the fan-shaped segments from bending and deformation during the use of the integral through rollers, most of them use segmented rollers, which are supported by bearings.

[0003] The prior art (patent number: CN203944810U) discloses a support structure for a continuous casting roller of a slab continuous casting machine sector, wherein the sector includes a frame and a continuous casting roller, a transmission device, and a pressing device arranged on the frame. The continuous casting roller is installed on the frame through a continuous casting roller bearing seat. The pressing device drives the continuous casting roller to press down and deform the slab, and the transmission device drives the continuous casting roller to rotate for conveying the slab. A support device is arranged between the frame and the continuous casting roller. The beneficial effects of the utility model are as follows: since the support device on the sector of the continuous casting machine is arranged outside the continuous casting roller, the structure of the continuous casting roller is greatly simplified; the continuous casting roller can be made into a large roller diameter integral roller with a simple structure, so that its strength and rigidity are significantly increased; the continuous casting roller and the support device are easy to disassemble, assemble and replace, the maintenance workload is greatly reduced, and the consumption of spare parts is significantly reduced; at the same time, the continuous casting machine is more suitable for high load conditions when large pressing is implemented at the end of solidification.

[0004] The existing wide slab continuous casting sector segment integral clamping roller has the following disadvantages. Since the existing clamping roller disassembly process is relatively complicated, the clamping roller is not easy to disassemble and repair. Therefore, we propose a new wide slab continuous casting sector segment integral clamping roller. Utility Model Content
