摘　　要：根据STANNEX电极的热导率曲线,以平壁导热为模型,建立了锡电极中心轴向温度分布的简化数学模型,根据锡电极使用的实际情况建立实验炉,测试了锡电极在稳态下的边界温度以及锡电极中心在稳态下的实际温度分布,根据实验测得的边界条件对锡电极的温度分布作推导,得出了锡电极的轴向温度分布,对电极导电的牵引(如采用哪种联结材料,选择合适的连接方式)具有指导意义,同时对玻璃电熔炉的散热与功率配置以及电极使用过程中的冷却提供了参考,根据实际温度情况采取相应的冷却措施,从而可以延长电极的使用寿命。According to the model of piano - mural heat transfer and the thermal conductivity of STANNEX tin oxide electrodes manufactured by DYSON INDUSTRIES LTD, the simplified mathematical model of the electrodes＇ axial temperature gradient, which especially fits the central temperature, was established. Further more, the electrodes＇temperature gradient under certain boundary condition were carefully calculated. Itg significantly guiding reference for selecting electrode material and determining power disposition of the glass melting furnace. At the same time, it conduces to adopt proper cooling measures for electrodes so as to prolong the life - span of the electrode in glass melting.
