Title: METHOD OF CONTROLLING AN ALUMINUM REDUCTION CELL
Summary: Logic electrolytic cell control program, which will be used to increase the efficiency of management process and maximize TEP work electrolyzers.
Technology Benefits : A control logic program increases the number of monitored parameters of operation of the cell, quickly choose their optimal value, and supports a maximum period of time for maximum TEP.
Technology Applications : This invention refers to aluminum metallurgy, specifically, the method of producing aluminum by molten salts reduction.
Detailed Technology Description: On the resistance of the electrolizer is measured voltage drop and the current series. Produce calculation error of the heating power of the set value and determine the dynamic parameters of operation of the electrolizer. Based on dynamic parameters comprehensively assess the technological state of the electrolizer and choose the optimal value, which supports a maximum period of time by moving the anode and control of spontaneous changes in the voltage drop across the electrolizer. Increase the time optimal operation of the electrolizer to maximize the production of aluminum and minimum power consumption.

Title of PCT application: METHOD OF CONTROLLING AN ALUMINUM REDUCTION CELL
PCT application Date: 22.05.2015
PCT application description (abstract): This method consists in measuring the resistive voltage drop in the reduction cell, comparison of the measured value with the set voltage drop value in the reduction cell and elimination of the mismatch by the relevant anode displacement. The anode displacement reduces the mismatch between the heating power and the set value until the minimum power is released in the reduction cell. Release of the minimum power is determined by the spontaneous growth of the electrochemical component of the reduction cell voltage, this mismatch is maintained with the relevant anode displacement without any variations in the thermal state of the reduction cell.The invention enables to reduce the electric power consumption, enhance the current metal yield and reduce the labor intensity of reduction cell maintenance.

Patent title: Способ управления алюминиевым электролизером
Patent Date: 19.11.2001
Patent description (abstract): Способ управления алюминиевым электролизером заключается в измерении падения напряжения на сопротивлении электролизера, состоящем из электрохимической и оммической составляющих. Измеренное значение сравнивают с заданной величиной падения напряжения на электролизере. рассогласование устраняют соответствующим перемещением анода. Относительно заданного падения напряжения на электролизере устанавливают зону падения напряжения, равную величине возможного изменения электрохимической составляющей падения напряжения. В этой зоне перемещение анода осуществляют по рассогласованию греющей мощности от заданного значения. период изменения греющей мощности устанавливают равным периоду устранения рассогласования без изменения теплового состояния электролизера.
