【摘要】 真空氮化炉体中炉壳的设计壁厚主要涉及到工作温度、真空度和炉膛尺寸等工艺要求。为了安全起见,按照传统的经验设计方法,工程中通常采用超厚壁炉体,这样不仅导致了材料的浪费,更重要的是会造成真空氮化炉热效率极低的现象(通常热效率<37%)。针对真空氮化炉体设计工艺参数是变量的问题,利用ANSYS及其参数化语言对炉体结构进行优化设计。通过研究构建了真空氮化炉体相关尺寸的优化序列及曲线,与传统经验公式计算结果相比,其用材减少了13%,热效率显著提高。更多还原

【Abstract】 The design of shell thickness of Vacuum nitriding furnace mainly involves the technologi-cal requirements such as working temperature,vacuum chamber and the size of hearth.For security purpos-es,people usually use super thick shell according to traditional methods,which results in both materials waste and also very low thermal efficiency of the vacuum nitriding furnace phenomena(usually thermal effi-ciency is lower than 37 percent).Since the design parameters of vacuum nitriding furnace are variables,it uses ANSYS parametric language to optimize the design of furnace.Through the research the optimal se-quence and curve for relevant dimensions of the vacuum nitriding furnace is constructed,which the results show after being compared with traditional experience formula,the timber is reduced significantly by 13% as well as the thermal efficiency is increased obviously.更多还原
