| Abstract: | Heat transfer mode of Zr-4 alloy sheet during vacuum annealing is analyzed, and the radial heat transfer coefficient of Zr-4 alloy sheet is calculated. The temperature field of Zr-4 alloy sheet during annealing was simulated by using ABAQUS, and the influence of fixture on annealing of Zr-4 alloy sheet was analyzed. The numerical simulation results were verified by experimental measurement. The results show that the fixture can improve the uniformity of temperature distribution of zirconium alloy sheet, and the numerical simulation results are in good agreement with the measured results. |
