| Abstract: | This paper analyzes the reasons of invalidation of radiant tube during production of heat treatment furnace and the measures to solve the problem. The invalidation of radiant tube includes its bending and deformation, falling down from the hanging, which causes radiant tube being broken and damaged. Detail analysis, in terms of temperature change and hanging condition, is made to find out the reasons of radiant tube invalidation and corresponding contermeasures. As a result, the service life of radiant tube has been prolonged. |
