在设计用于粉末盘温度梯度热处理的工装时,需要考虑盘坯的形状、蓄热块的材质和尺寸以及绝热材料的材质及其厚薄、炉温等因素对温度梯度的大小和保持时间的影响。如果完全通过试验进行研究,不但需要较长的时间而且需要较高的经费支撑。本研究通过采用有限元数学计算的方法,对不同几何形状组合的盘坯与工装在处理过程中的温度梯度进行了模拟,对盘坯和工装的设计进行优化,最终获得了满足粉末盘温度梯度热处理要求的工艺方案。
When designing the tooling for temperature gradient heat treatment of powder disk, it is necessary to consider the shape of the disk blank, the material and size of the heat storage block, the material of the heat-insulating material, the thickness of the heat-insulating material, the temperature of the furnace and other factors on the temperature gradient and the holding time . If fully through the study of the test, not only takes a long time but also requires high financial support. In this study, the temperature gradients in the process of processing the billet and tooling with different geometric shapes were simulated by finite element method, and the design of the billet and tooling was optimized. Finally, the temperature gradient Heat treatment process requirements.
