Description
Известен способ определени концентрации глинозема по величине критической плотности тока с применением вспомогательного анода, изготовл емого из угл , графита, кпрбидо или боридов металлов.A known method for determining the concentration of alumina by the magnitude of the critical current density using an auxiliary anode made from coal, graphite, redbido or metal borides.
Предложено концентрацию глинозема в электролите определ ть по величине критической плотности тока, измер емой вспомогательным анодом.It has been proposed to determine the concentration of alumina in the electrolyte by the value of the critical current density measured by the auxiliary anode.
Через тело непрерывно самообжигающегос анода / алюминиевого электролизера с верхним токоподводом (см. чертеж) пропускают вспомогательный анод 2, который может быть собран из отдельных элементов 5. Вспомогательпый анод электроизолируют от основного рабочего анода путем плотного покрыти его поверхности огнеупорным изол ционным материалом 4, например окисью алюмини , заключенной в металлическую трубку 5 или же в оплетку из асбеста, пропитанного силикатом .An auxiliary anode 2 is passed through the body of the continuously self-burning anode / aluminum electrolyzer with the upper current lead, which can be assembled from individual elements 5. The auxiliary anode is electrically insulated from the main working anode by densely covering its surface with a refractory insulating material 4, for example, oxide aluminum encased in a metal tube 5 or in a braid of asbestos impregnated with silicate.
Оба анода подключают в одну цепь в период нормальной работы и отключают вспомогательный анод от общей цепи на период нзмерени критической плостности тока.Both anodes are connected to one circuit during normal operation and the auxiliary anode is disconnected from the common circuit for the duration of the critical current density.
Дл определени критической плотности тока через вспомогательный апод пропускают посто нный ток, плотность которого в 1,5- 10 раз больше плотности тока рабочего анода.To determine the critical current density, a direct current is passed through the auxiliary apode, the density of which is 1.5 to 10 times the current anode current density.
