By analysis on baking data of 300kA large-type prebaked cells,the deficiency existing in original baking start-up process was discovered,and then improvement measures were taken accordingly.

Energy saving, consumption reducing and baking start-up technology in large-scale pre-baked aluminum electrolysis cell have been being come to attention by producing managers and academicians.

This paper introduces the energy-saving practical experience during baking start-up of 300KA aluminum electrolysis smelting cells,putting forward some energy-saving concepts on power-on baking,start-up,parameter management,such as voltage,bath temperature,two levels,etc.

Analyses of anode faults in the course of baking and start-up of aluminum electrolysis cell;
