Pot lining life is one of main factors on pot performance and consequence to metal production cost. The lining life depends on the structure of material and design of pot lining. INALUM as Indonesian flag aluminium smelter uses improved design by reinforcement of sidewall lining using thicker Silicon Carbide (SiC) (550Lx505Wx100T mm), improvement of cathode assembly using longer cathode block (3500Lx505Wx450H mm) and bigger collector bar (4770Lx220Wx155H mm). Study and test have been conducted for D5-1 design (non back-up brick behind SiC) and D5-2 (using back-up brick SK-32 behind SiC). D5-1 pot design improved CVD by 10 mV hence there is opportunity to improve DC Consumption and productivity by 31 kWh/T.Al or 3.1 kg/pot.day. D5-2 pot design improved Cathode Voltage Drop (CVD) by 7.6 mV hence there is opportunity to decrease DC Consumption by 32.2 kWh/T.Al and increase productivity 3.0 kg/pot.day.
