摘要(Abstract)：

为了提高连续式热处理炉内部温度场的温度均匀性及加热效率，以一种推舟式连续热处理炉为参考进行建模，采用ANSYS FLUENT软件模拟了稳态条件下连续炉内部温度场的分布规律，并将模拟结果与实测结果进行对比分析，最大误差在10%以内。在此基础上，研究加热管直径、管排间距和进气口位置对炉体内部温度均匀性及加热效率的影响，并以此优化加热系统。结果表明，低温加热段适当将上排加热管下移和侧面进气口上移可提高炉体内部温度均匀性和加热效率，改变加热管径对低温段系统影响不大；高温段适当改变管截面尺寸和上移侧面进气口可有效提高炉体内部温度均匀性和加热效率，改变管排间距则对高温段系统影响不大。具体优化方案为：低温加热段加热管直径?60 mm,上排加热管下移300 mm,侧面进气口上移400 mm;高温加热段加热管截面尺寸8 mm×28 mm,侧面进气口上移100 mm。优化后低温段加热工件中心与边缘平均温差由原来的48.5℃降低到30.8℃;高温段由原来的140.8℃降低到16.1℃,显著提高了炉体内部温度均匀性和加热效率。
