Abstract： 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 processequipment were determined.The numerical thermal simulation method，implemented by ANSYS software and validated through experiments，was employed to analyze the heat treatment processforthe test plate and the corresponding equipment.The resultsdemonstrate that the temperature distributionand holding temperatureof the testplate alignclosely with those of the equipment，confirming the feasiblity ofderiving the equipment's heattreatmenttechnique 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 transfercalculations were used toformulate equations fortest plates with varying material and thicknesses.These formulasalow for thedetermination of heat treatment techniques for equipment of different materials and thicknesses using a single testplate.Theresults indicate that the temperature gradient across the plate thickness increases with thickness， and when the thickness exceeds 120mm ， single-sided heating may cause treatment failure due to excessive temperature differences between the two sides.Moreover， material properties such as specific heat capacity andthermal conductivity influence the heattreatment process： materials with higher specific heat capacity have lowerthermal conductivity，and higher heat treatment temperatures require longer processing times and greater energy consumption.
