【Abstract】 The theoretical calculation of the electrolyte temperature variation rule and heat loss during pole changing of 240kA prebaked cell was represented.Three measures were put forward to reduce disturb of steady heat equilibrium produced by pole changing working,which was controlling the time of null pole precisiously,compensating the pole changing voltage of cell control system reasonably,and setting the setting voltage of pole changing day.更多还原
