摘要： An electrolytic cell for producing primary aluminum by using inert anodes is disclosed, in which an electrolyte system KF—NaF—AlF3 is used and the operating temperature of the cell is 700-850° C. The electrolytic cell comprises a cell shell, heat insulating refractory lining, a melting pot, a heat insulating cover, inert electrodes, electrode stems, anode bus-bars, cathode bus-bars, anode branching bus-bars, heat insulating plates, partitions between anodes and cathodes and a feeding device. The quality of the aluminum product obtained by using the electrolytic cell is not less than 99.7%. The cell is free from emission of carbon dioxide and perfluorinated compounds (PFCs), and hardly has consumption of electrodes, so the distances between anodes and cathodes can be kept stable. The cell is sealed and the volatilization of dust and fluorides can be prevented, and it is useful to recover oxygen gas.

摘要： A method for measuring temperature and electrolyte level of a molten electrolysis bath in a cell for production of aluminum by electrolysis of alumina includes the steps of: (a) piercing the crust of a solidified bath with a crust breaker and immersing into the electrolyte, an extremity of a temperature probe to a sufficient depth until an initial temperature reading of at least 850.degree. C. is measured, then maintaining the immersion of the probe, in said electrolyte for a length of time which is less than the time taken to establish the thermal equilibrium of the probe in the electrolyte, (b) withdrawing the probe and determining a temperature of the electrolyte by extrapolation of the temperature values measured by the probe, (c) measurement of the level of electrolyte in the cell by moving the lower extremity of the probe into contact with the electrolyte while recording potential signals between the cathodic substrate and the probe, and recording position signals corresponding to the position of the probe, and (d) determining the level of the electrolyte by comparison of recorded potential and position signals.
