Abstract

1,145,820. Electro-physical measurement. SIEMENS A. G. July 26, 1968 [July 28, 1967], No. 35918/68. Heading G1N. A method of determining the operative state of an electrolytic aluminium furnace comprises altering the anode/cathode spacing by a known amount and measuring the change in anode/cathode resistance. Since the resistance of the supply lead and the anode-gas-resistance is constant during the change the result is the resistance of the melt (per unit length) which is indicative of the concentration of aluminium oxide. The result may be fed to a "computor" to automatically control the charging of the furnace to maintain optimum oxide concentration (i. e. optimum efficiency).
