[0002] Continuous casting is the abbreviation of Continuous Steel Casting. In the process of producing various steel products in steel mills, there are two methods of using molten steel to solidify and shape: traditional mold casting and continuous steel casting. The rapid development of continuous casting technology is a very eye-catching trend in the development of contemporary steel industry. Nowadays, for steelmaking enterprises, whether it is long-process steelmaking or short-process steelmaking, the equipment of continuous casting machines has almost become inevitable.

[0003] In recent years, continuous casting and rolling have become the mainstream technical equipment of metallurgical enterprises. Whether it is continuous casting or continuous rolling equipment, rollers are very important components of each major equipment. From continuous steel casting to steel rolling, most of the work is carried out on the rollers. Therefore, the quality and service life of the rollers play a vital role in metallurgical production, especially the rollers of the continuous casting machine are in direct contact with the high-temperature ingots of 750-900℃ for a long time. Its high-temperature comprehensive mechanical properties and resistance to thermal deformation are the key concerns of designers, manufacturers and users. Therefore, researching and developing a conveyor roller with good high-temperature comprehensive mechanical properties, strong cooling effect and strong resistance to deformation is a long-term goal and key task pursued by metallurgical workers.

[0006] Preferably, a roller neck 1 and a roller neck 2 are fixedly connected at both ends of the roller body, a through hole is opened in the roller neck 1, the water pipe passes through the through hole and extends to the outside of the roller body, and the outer diameter of the water pipe is smaller than the inner diameter of the through hole to form a drainage channel.

[0007] Preferably, a plurality of support columns are fixedly arranged in the cavity corresponding to the plurality of support parts, the water pipe is fixedly installed in the plurality of support columns, each of the support columns is provided with channel one and channel two, the channel one connects the water pipe with the water flow channel, and the channel two connects the cavity with the water flow channel.

[0008] Preferably, the support portion includes a pair of side roller rings and a plurality of middle roller rings.

[0009] Beneficial Effects

[0010] The utility model provides a water-cooled conveying roller for continuous casting slabs, which has the following beneficial effects: the device can cool the supporting part by arranging a water flow channel in the supporting part, and can cool the roller body by arranging a cavity in the roller body, thereby improving the overall service life of the conveying roller, and the water pipe and the cavity are connected on both sides of the water flow channel respectively, which can reduce the water flow dead angle in the water flow channel and ensure the uniformity of cooling.
