摘要(Abstract)：

采用ANSYS FLUENT有限元软件对连续式高温热处理炉内部温度分布进行数值模拟，并与实测数据进行对比，平均相对误差为6.2%,验证了模型的准确性。在此基础上，研究不同移动速度、加热带结构和温度设定方式对碳化硅工件温度均匀性和加热效率的影响。结果表明：降低工件移动速度有利于提高工件的温度均匀性和加热效率，移动速度为0.025 m/min时，相较于0.033 m/min,工件顶点和中心平均温差降低14.5%;与三面连续加热和四面多段加热相比，四面连续加热可同步提高加热效率和温度均匀性，与三面连续加热相比，工件顶点与中心平均温差降低35.05%;间隔1 m一个温区加热较为合理，相较于间隔3 m一个温区加热，工件顶点和中心平均温差降低41.28%,显著提高了温度均匀性。
