Abstract
The invention relates to a carbon block group, and especially relates to an anode carbon block group used for an aluminium electrolysis cell The anode carbon block group comprises an aluminium guide rod and an anode carbon block; a steel beam is arranged between the aluminium guide rod and the anode carbon block; and conductive steel rods are arranged between the steel beam and the anode carbon block. Advantages of the anode carbon block group are that: the anode carbon block group is not provided with traditional phosphorus iron which is used for connecting a guide rod group with the anode carbon block, so that ion-carbon contact pressure of the anode carbon block group is reduced effectively. Changing of the structure of the anode carbon block group is capable of reducing the ion-carbon contact pressure of the electrolytic cell anode carbon block group, and is beneficial for reduction of voltage of the electrolytic cell, and alternating current consumption of electrolytic cell aluminium production is reduced.
