This paper analyzes the importance of aluminum bath composition and molecular ratio in aluminum industrial production, and points out the drawbacks of current bath molecular ratio measurement based on traditional fluorescence spectrum to analyze the bath analysis curves. Therefore the technical connotation, optical principle and quick detection advantages of the oxygen measurement method to analyze the bath composition are discussed, and the calculation formula of the molecular ratio is presented. The comparison verification between the oxygen measurement method for analyzing the bath composition and the laboratory analysis from the Zhengzhou non-ferrous metals research institute Co., Ltd., of CHALCO is carried out. The comparative test and industrial batch test results show that the oxygen measurement technology described in this paper has a good effect, which coincides well with the process as well.
