Abstract: In order to meet the temperature uniformity requirements of a high precision plate aging furnace, a diversion structure was added, of which the structure parameters were optimized by numerical simulation method, and then the temperature uniformity test of the aging furnace was carried out on the basis of the simulation results. The results show that using the optimized diversion structure can improve the temperature uniformity of the aging furnace within ±1.5 ℃, and the simulation results is consistent with the measurement result showing that reasonable setting diversion structure can achieve the requirements of the temperature uniformity of the aging furnace.

Key words: aging furnace, heat treatment, furnace temperature uniformity, diversion structure
