[0002] The roller table of a continuous casting machine refers to the roller table system used in the production process of a continuous casting machine. A continuous casting machine is a device for casting by continuous casting, which continuously casts molten metal into billets or plates. After the molten metal comes out of the mold, it needs to be cooled by the roller table in the secondary cooling zone.

[0003] When the existing spraying device for the roller table in the secondary cooling zone cools the conveyed crystallized metal, there are the following problems: 1. Uneven spraying: Improper nozzle arrangement or blockage will lead to uneven spraying. Some areas may not achieve the required cooling effect, thus affecting the product quality. 2. Insufficient or excessive spraying volume: Insufficient spraying volume will result in insufficient cooling effect, which may cause unstable metal temperature or uneven product surface. Excessive spraying volume may cause waste of water resources and increase the cleaning work. 3. Improper spraying angle: Incorrect spraying angle may also lead to poor cooling effect, and even damage the equipment or product quality in inappropriate cases.

Clamping blocks 31 adapted to the first grooves 21 are arranged on both the left and right sides of the annular pipe bracket 3 connected to the arc-shaped bracket 2. A second groove 32 adapted to the driving block 22 is arranged inside the clamping block 31 (by clamping the clamping block 31 and the driving block 22, the driving block 22 can drive the annular pipe bracket 3 to swing back and forth by rotating back and forth, thereby driving the sliding nozzle 4 to swing reciprocally to realize the angle adjustment of the nozzle and make the spraying uniform).
