Sustainable Mining and Metallurgy

The original cell control technology of electrolytic aluminum enterprises is based on a single resistance signal to judge whether the operation of the electrolytic cell is stable, which cannot achieve the visual effect, and lacks the functions of collaborative control, optimization decision making and abnormal situation diagnosis. With the gradual enlargement of the electrolytic cell type, there are more and more problems that cannot be predicted in advance only by manual experience. Taking 400kA series electrolytic aluminum of electrolytic aluminum enterprise as the research object, a new digital slot control computer was developed. The composition and function of the new digital control system were introduced, and the system was applied in practice. The research shows that with the cooperation of the new intelligent optimization control system, the prevention ability and production stability of the 400kA series electrolytic cell emergencies are greatly improved, the power consumption and the cost of production raw materials are significantly reduced, and the labor efficiency and the stability of the electrolytic cell operation are significantly improved.
