摘要
针对核工业专用材料热处理问题提出了一种内外双真空热处理炉的设计方案,同时解决了工件不能受加热污染以及精密生产车间热环境严格受控的特殊需求。介绍了内外双真空热处理炉的整体结构设计,重点提出马弗炉管在加热室受热膨胀伸长的解决方案,构建了内外双真空系统,并对加热室进行了数值仿真模拟分析和现场实验验证,实验验证结果与仿真模拟结果表明所设计内外双真空热处理炉温度及均匀性满足工艺要求,测试结果中内外双真空热处理炉真空压力、抽空效率、降温效率等指标均满足工艺要求。该设备的研制为同类装置的设计提供了科学依据与实践指导。
A dual-vacuum heat treatment furnace design scheme has been proposed for dedicated materials in the nuclear industry,which simultaneously addresses the special requirements of preventing workpiece contamination during heating and maintaining strict thermal environment control in precision production workshops.The overall structural design of the dual-vacuum heat treatment furnace is introduced,with emphasis on the solution proposed to accommodate the thermal expansion and elongation of the muffle furnace tube within the heating chamber.A dual-vacuum system has been constructed,and numerical simulation analysis along with on-site experimental validation has been conducted for the heating chamber.Both the experimental and simulation results indicate that the temperature and uniformity of the designed dual-vacuum heat treatment furnace meet the process requirements.Test results show that key indicators such as vacuum pressure,pump-down efficiency,and cooling efficiency all meet the process specifications.The development of this equipment provides a scientific basis and practical guidance for the design of similar apparatus.
