Description
);iN. При этом установлено, что дл каждого iiiiia ..чекгролизсрог, ларактерси нидипидуальиый диапазон частот кодебаии рабочего )iaпр жени , св занный пр мой пропорциональностью с диапазоном нормальных рабочих температур электролита.); iN. It has been established that for each iiiiia, a check of control, a range of frequencies, and a range of frequencies for the codec of the worker’s i) voltage, which is directly proportional to the range of normal working temperatures of the electrolyte.
Автоматизированный контроль температуры электролита может быть реализован с помощью регистратора низкочастотных колебаний электрического напр жени , пригодного дл регистрации колебаний частотой до нескольких герц и ам.плитудой до нескольких сотен милливольт, а автоматический контроль- при помощи, например, электронной вычислительной машины, вход щей в структуру автоматизированной системы управлени процессом электролиза алюмини путем подключени ее на онределенпое врем к участку анод-катод каждого контролируемого электролизера .Automated electrolyte temperature monitoring can be implemented using a low-frequency oscillation recorder of electrical voltage, suitable for recording oscillations with a frequency of up to several hertz and a small screen of up to several hundred millivolts, and automatic control using, for example, an electronic computer included in the structure an automated system for controlling the process of electrolysis of aluminum by connecting it for a definite time to the anode-cathode section of each controlled electr Leeser.
Выделение диапазона колебаний частот 0,5-2,0 Гц может быть существенным при использовании в качестве регистратора низкочастотных колебаний электрического напр жени , например, стандартного многопредельного самонищущего милливольтметра типа Н-39 при скорости его лентопрот жного механизма 5400 мм/ч.Allocation of the frequency range of 0.5-2.0 Hz can be significant when using low-frequency oscillations of an electrical voltage as a recorder, for example, a standard multi-limiting self-searching millivoltmeter type H-39 at a speed of 5400 mm / h.
Контроль температуры электролита в алюминиевом электролизере с верх-ним токоподводом осуществл ют следующим образом.The temperature control of the electrolyte in the aluminum electrolyzer with the upper current lead is carried out as follows.
Подключают регистратор низкочастотных колебаний электрического напр жени в диапазоне 0,5-2,0 Гц к участку анод-катод нормально работающего электролизера в период времени между двум последовательными операци ми по обслуживанию электролизера, но пе ранее, чем через экспериментально установленное дл конкретной серии электролизеров врем (например 1 ч) после проведени первой из этих операций. При этом врем одной pei-истрацпи колебаний рабочего напр жени контро.шруемого у.чектро.чнзсра Bi,i6 iраетс предночтительно в пределах от 10 до 20 с, исход из требований к оперативности контрол и точности определени средней частоты колебаний рабочего напр же)н .A recorder of low-frequency electric voltage oscillations in the range of 0.5-2.0 Hz is connected to the anode-cathode section of a normally operating electrolyzer during a period of time between two consecutive operations for servicing the electrolyzer, but not earlier than the experimentally determined time for a specific series of electrolyzers (for example, 1 hour) after the first of these operations. In this case, the time of one pei-istratspi oscillations of the operating voltage of the concurrent u.chektro.chnsra Bi, i6 is preliminarily in the range from 10 to 20 s, based on the requirements for speed of control and accuracy of determining the average frequency of oscillations of the operating voltage)
