In this paper, the crack of the saggar was solved by finite element method, and the reason of the crack was found out through calculation and analysis. Then, the optimized design of the saggar was carried out, and the longitudinal stiffness of the saggar was strengthened, and the connection mode between the saggar and the saggar was changed. After calculating the optimized equipment support and sagger, it is found that the maximum stress of sagger is reduced by about 95% compared with that before optimization, which meets the requirements of strength design, indicating that the optimized scheme is very effective.
