摘　　要：为确定设备局部热处理工艺,建立了可提供破坏性检测的热处理试板,通过边界条件分析,确定了热处理试板与过程设备等效的边界条件,采用经过实验验证的ANSYS热分析数值模拟方法对热处理试板和对应的过程设备热处理过程进行分析,发现二者加热和保温后的温度场分布基本一致,可通过对热处理试板进行热处理实验确定热处理工艺,进而得到过程设备的热处理工艺。热处理试板制作工艺复杂,利用范围窄,为提高其利用率,建立不同材料和不同厚度热处理试板热处理工艺的计算公式,经过等效,使得一种材料和厚度的热处理试板可模拟多种材料和厚度试板的热处理工艺。研究结果表明,热处理试板壁厚方向温差随壁厚的增加而增加,当壁厚超过120 mm,若采用单面加热,内外壁温差过大,可能导致热处理失败;不同材料热处理试板存在比热容和导热系数差异,也存在热处理温度差异,比热容越大、热导率越低及热处理温度越高的材料需要越长的热处理时间,同时消耗更多能量。To establish a localized heat treatment technique,a heat treatment test plate capable of withstanding destructive testing was developed.Through boundary condition analysis,the equivalent boundary conditions for both the heat treatment test plate and the process equipment were determined.The numerical thermal simulation method,implemented by ANSYS software and validated through experiments,was employed to analyze the heat treatment process for the test plate and the corresponding equipment.The results demonstrate that the temperature distribution and holding temperature of the test plate align closely with those of the equipment,confirming the feasibility of deriving the equipment’s heat treatment technique from the test plate results.However,the complex manufacturing processes of the test plate make single-use applications economically unviable.To enhance its utility,thermodynamic and heat transfer calculations were used to formulate equations for test plates with varying materials and thicknesses.These formulas allow for the determination of heat treatment techniques for equipment of different materials and thicknesses using a single test plate.The results indicate that the temperature gradient across the plate thickness increases with thickness,and when the thickness exceeds 120 mm,single-sided heating may cause treatment failure due to excessive temperature differences between the two sides.Moreover,material properties such as specific heat capacity and thermal conductivity influence the heat treatment process:materials with higher specific heat capacity have lower thermal conductivity,and higher heat treatment temperatures require longer processing times and greater energy consumption.
