摘　　要：电解温度与稀土熔盐电解槽电流效率、炉体寿命紧密相关,然而热电偶测温、红外热成像等测量方法受电解车间高温强腐蚀环境影响难以实时检测。基于YOLOv8算法对熔盐电解槽炉面温度进行预测。首先,通过高温试验炉自制温度数据集并基于YOLOv8算法训练获得温度区间分类模型;其次,采用图像灰度与温度关系式重建炉面图像温度云图;最后,基于YOLOv8-SSW算法构建了炉面温度图像识别模型,其预测准确率为93.4%,可用于电解槽炉面温度监测。The electrolytic temperature is closely related to the current efficiency of the rare earth molten salt electrolyzer and the life of the furnace body.However,it is difficult to detect the electrolytic temperature in real time by thermocouple measurement and infrared thermal imaging due to the high temperature and strong corrosive environment of the electrolysis workshop.The furnace surface temperature of molten salt electrolyzer was predicted based on YOLOv8 algorithm.Firstly,the temperature interval classification model was obtained through the selfmade temperature data set of high temperature test furnace and trained based on YOLOv8 algorithm.Secondly,the temperature cloud map of the furnace surface image was reconstructed using the relationship between image gray level and temperature.Finally,the image recognition model of furnace surface temperature was constructed based on YOLOv8-SSW algorithm,and its prediction accuracy is 93.4%,which can be used to monitor the furnace surface temperature of electrolytic cell.
