PROCESS OF PREPARATION OF ALUMINUM ELECTROLYZER TO START AFTER OVERHAUL Russian patent published in 1998 - IPC

Abstract RU 2115772 C1

FIELD: production of aluminum. SUBSTANCE: chips of aluminum and its alloys are laid without pressing on surface of hearth in continuous uniform layer having thickness of 2-3 interpole distances. Then layer of chips is compacted by installation of anode on it to thickness equal to 0.9-1.1 interpole distance to hearth. EFFECT: prolonged service life of electrolyzer due to qualitative firing of cathode, uniform distribution of currents and heating of hearth.
