Abstract

Abstract: Heating element parameters are the key factors affecting the temperature uniformity and workpiece sintering quality for vacuum sintering furnaces. This study investigates the effects of heating element diameter, distance from the furnace wall, and element quantity on temperature uniformity through orthogonal experiments. The results demonstrate that the number of heating elements has the most significant impact on temperature uniformity, followed by the distance from the furnace wall, while the diameter of heating elements exhibits a negligible influence. The optimized parameters are determined as follows: heating element diameter of 36 mm, distance from furnace wall of 65 mm, quantity of 10 heating elements, and inter-element spacing of 150 mm. Compared to that of the original design configuration, the optimized maximum temperature difference between workpieces is reduced by 44.0 ℃, corresponding to a 36.25% improvement. The results of our work may provide a technical reference for the design and optimization of heating elements in vacuum sintering furnaces.

Key words: vacuum sintering furnace, temperature field simulation, heating element parameters, furnace temperature uniformity
