Description

Technical Field

[0001] The utility model relates to the field of annealing furnace rollers, in particular to a high-strength annealing furnace roller. Background Art

[0002] The annealing furnace zone is exposed to high temperatures of 1000-1300°C for extended periods. If the furnace rollers operate at these temperatures for extended periods, their service life will be significantly shortened. Therefore, the bottom conveyor rollers need to be cooled. If the cooling effect is inadequate, nodules will form on the roller surface, causing the rollers to deform or even stop rotating. This not only affects product quality but also causes significant wear and tear on the rollers, shortening their service life. Annealing furnace rollers are typically equipped with a cooling mechanism to prevent excessive thermal expansion caused by high temperatures, reduce thermal stress, and ensure they maintain stability and longevity within their normal operating temperature range.

[0003] The current patent number is "201420404457.4", and the patent name is "A kind of annealing furnace roller with cooling structure". The patent discloses a roller body, which includes a roller wall, an upper connector and a lower connector. The roller wall, the upper connector and the lower connector are correspondingly surrounded by an accommodating space. The upper connector and the lower connector are connected to the two ends of the roller wall. The upper connector is provided with an axial hole along the axis, and a water pipe is fixed in the axial hole.

[0004] The inventor believes that the hollow design of the interior of the furnace roller will lead to insufficient strength of the furnace roller itself. Therefore, it is necessary to design a furnace roller with good cooling effect and furnace roller body structural strength that meets the requirements. Utility Model Content
