Abstract

Coke bed preheating with shunt rheostats is considered one of the most popular methods used in the aluminium reduction cells preheating. Typical cathode heat-up rate during preheat and start-up as well as typical start-up anode effect were achieved. This paper studied the important considerations affecting the preheating and start-up of 210 kA prebaked cells at Egyptalum, as well as the evaluation of performance of the coke bed preheating method with shunt rheostats. The average preheating time was found to be 53 hours with energy consumption of up to 115,000 kWh. The effect of using different shunts-rheostats materials on cell current was illustrated. Also cell voltage before, during and after finishing the anode effect was studied. It was found that the cell voltage and time of anode effect during this stage varied in the range from 12 to 23 V and 60 to 120 min. respectively. The cell performance parameters, like current efficiency, energy and carbon consumption, were improved.
