Description

Technical Field

[0001] The utility model relates to the technical field of alloy roll processing, in particular to a device for removing residual stress on the surface of an alloy roll. Background Art

[0002] Alloy rolls refer to rolls made of tungsten carbide and cobalt using powder metallurgy methods. Alloy rolls are available in both integral and combined types. Due to their good wear resistance, high-temperature red hardness, heat fatigue resistance and high strength, they have been widely used in the production of rods, wire rods, threaded steel and seamless steel pipes, greatly improving the effective operating rate of rolling mills. However, when the alloy rolls are initially cast, there will be residual internal stress on their surface and shallow layer. When the alloy rolls are subjected to external impact force, the structure will collapse. Methods for removing stress include heat treatment and tapping vibration, and the commonly used method of tapping vibration is shot peening to remove stress.

[0003] Existing equipment for removing residual stress on the surface of alloy rolls generally lacks the function of adjusting the position of the clamping structure and the nozzle according to the length of the alloy roll, and shot peening generally adopts a one-time use method, which is not convenient for recycling and saving consumables. Therefore, the utility model provides an equipment for removing residual stress on the surface of alloy rolls. Utility Model Content
