Title: Electrolysis cell for winning aluminium - where carbon cathode hearth is connected to bus=bars via spaced graphite pegs increasing the efficiency of aluminium prodn.
Inventor: BRANDMAIR FRANZ DIPL CHEM DR R
IPC: C25C3/08
Filed: 1978-07-29
Abstract: The bottom ends of the anodes dip into a melt, floating on a layer of molten Al forming the cathode on a hearth made of carbon blocks. Below the carbon blocks is a row of cathode busbars connected to the carbon blocks by one or more pegs entering blind holes in the blocks. The number of pegs pref. decreases from the middle of the cell towards the ends of the cells; and the pegs pref. have a conical profile. The pegs and the blind holes in the blocks pref. have screw threads; and each peg may consist of two parts screwed together. The pegs are pref. made of graphite located in the blind holes in the carbon blocks via a stampable or castable mass. By reducing the number of pegs. in the longitudinal direction of the furnace, from the middle towards the end walls of cell, horizontal electric currents are avoided in the molten Al; these currents are most undesirable, as they air the Al so the distance between the anodes and cathode must be increased, thus impairing the efficiency of the process.
