Description

[0002] Heat-resistant metal roller ring is a kind of key component applied in specific industrial equipment (such as CSP heating furnace roller), and there is a certain optimization space in the structure design of current metal roller ring. When it is in the high-temperature environment such as CSP heating furnace, the problem of uneven internal thermal stress distribution of roller ring gradually highlights under the action of continuous high temperature. This is because there is difference in heating degree of each part of the roller ring during heating, and the existing structure cannot effectively coordinate the stress change caused by this temperature difference.

[0003] To solve this problem, the conventional method is to select a material with lower thermal expansion coefficient, hoping to reduce the generation of thermal stress. However, such materials are often expensive, which will greatly increase the production cost. Another common means is to forcibly cool the roller ring during use, such as using water cooling method to reduce the surface temperature of the roller ring. But this can easily cause the temperature difference between the inside and outside of the roller ring to further increase, which in turn aggravates the internal thermal stress concentration. Long-term use of this method can easily cause the roller ring to crack and other damage, which seriously affects its service life and working stability, so a new structure is needed to solve the above technical problems.
