This study is devoted to improving the economic efficiency of the cell, due to the field of the generated electromagnetic field’s accurate diagnostics. To solve this problem, the authors had developed a hardware-software complex for electromagnetic field diagnostics. This complex includes a measurement device and a software package for data collection and analysis. On the laboratory prototype of the aluminum electrolysis complex, a study was carried out on the formation and structure of the electromagnetic field. A number of experiments have been carried out showing the degree of formation of the electromagnetic field by the anode, the relationship of electromagnetic fields in the inter-anode space has been shown. Based on the results of the studies, conclusions were drawn about the possibility of diagnosing the current state of the anode, determining the direction of rotation of aluminum in the electrolytic cell and estimating the life of the anode and its burnout time.

“…Along with the problem of the absence of an automated control system for the main technological parameters of the alumina reduction process (determination of the bath temperature, cryolite ratio, metal and bath levels), there is a problem of crust forming on the surface of the melt in the feeder hole (Figure 1) [7][8][9]. The crust is located on the surface of the cryolite and covers it.…”

For efficient operation of high-power aluminum reduction cells with prebaked anodes,full-time monitoring of the main technological parameters is required.This article discusses a multifunctional crust breaker of the automatic alumina feeding system. It provides the alumina supply to the bath by breaking the continuously solidifying crust on the surface of the melt. The multifunctional crust breaker is also a part of the automatic alumina feed system, providing regular automatic measurements of the process parameters.This article describes the development of a laboratory bench with a multifunctional crust breaking device. The goal and objectives are set. The design of the device is presented in the paper. The paper shows the advantages of using an automatic alumina feeding system with the developed multifunctional crust breaker.The positive effect of using the bench in the training process is discussed.
