Description

TECHNICAL FIELD

[0001] The utility model belongs to heat -resisting roller technical field relates to a kind of heat -resisting roller of uniform cooling. BACKGROUND

[0002] In the process of guiding high-temperature objects, heat-resistant rollers are widely used to withstand extreme temperatures and maintain stable conveying of objects. However, these heat-resistant rollers have significant drawbacks in uniformly cooling high-temperature objects. The materials and designs of heat-resistant rollers are typically optimized for high-temperature resistance rather than cooling efficiency, which results in insufficient heat exchange between the roller body and the object in a high-temperature environment, making it difficult to achieve uniform cooling. Due to the limited heat conduction performance of heat-resistant rollers, the surface temperature of the roller body is unevenly distributed, which can cause local overheating or insufficient cooling when contacting high-temperature objects.

[0003] The root cause of these drawbacks lies in the limitations of the heat conduction performance and design of heat-resistant roller materials. To address these shortcomings, conventional methods include using materials with better heat conduction performance to manufacture heat-resistant rollers in the hope of achieving more uniform temperature distribution. However, these conventional coping methods also have drawbacks. Using high-heat-conduction-performance materials can help improve temperature distribution, but these materials are often costly and may have durability issues at extreme temperatures, affecting the service life of heat-resistant rollers.
