Description

Technical Field

[0001] The utility model relates to the technical field of roller cooling, in particular to a roller water circulation cooling device. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are mainly composed of a roll body, a roll neck and a shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. Rollers will generate heat due to friction during use. The heat generated will have a great impact on the quality of the rolls and workpieces. Therefore, the rolls need to be cooled during operation to avoid the temperature of the rolls from rising, so as to ensure the normal operation of the rolls. When the existing rolls are in use, cooling water will be transported inside the rolls to exchange heat and cool the rolls.

[0003] After searching, Chinese patent CN211564045U discloses a roller water circulation cooling device, which mainly cools the roller by opening an internal cooling channel with openings at both ends inside the main roller body at the outer edge and conveying cold water into the channel.

[0004] By comparing with the existing technologies in related fields, it can be seen that when the cooling water is used for heat exchange and cooling the rolling mill rollers, the cooling water temperature rises and scale will be generated inside the rolling mill rollers. The scale accumulates inside the rolling mill rollers, affecting the heat exchange efficiency of the rolling mill rollers. The accumulation of scale increases the difficulty of subsequent cleaning.

[0010] Furthermore, the filter unit includes a filter box, which is respectively installed at the ends of the water pipe and the drain pipe. The filter box is connected to the external cooling water delivery assembly, and the cooling water delivered into the water pipe by the external cooling water delivery assembly is filtered through the filter box.

At the same time, the sprayed cooling water accumulates at the lower end of the interior of the roller body 1, and the roller body 1 is continuously cooled by heat exchange and cooling by the accumulated cooling water. At the same time, under the elastic force of the spring 25, the spring 25 pushes the slide bar 27 through the limit plate 26, and the slide bar 27 drives the scraper 28 to press tightly inside the roller body 1 When the roller body 1 rotates, the scraper 28 is used to scrape the inside of the roller body 1 to prevent scale generated after heat exchange from accumulating in the roller body 1 and affecting the heat exchange efficiency.

[0033] It also includes a support beam 7, which is mounted on sleeves 24 arranged at equal distances.

[0037] like Figure 2 As shown, the cooling water in the roller body 1 slides down to the lower end of the roller body 1, and the roller body 1 is continuously cooled by the accumulated cooling water.
