Quality of anode carbon anode for aluminum electrolysis

　　High-quality anode carbon anode for aluminum electrolysis has the following characteristics:

　　 1. Good conductivity. To ensure that the anode current density is increased, the production capacity of the aluminum electrolytic cell is increased and the power consumption is reduced.

　　2. Good thermal shock and oxidation resistance.

　　3. The quality of anode carbon anode for aluminum electrolysis is uniform and stable to ensure stable electrolysis production, high efficiency and low consumption.

　　 4. It has certain tensile strength, flexural strength and large thermal expansion rate. At the same time, the anode is required to have less ash, low specific resistance, low porosity, less harmful elements, and compact structure.

　　Foreign advanced pre-baking tanks, due to the good quality of anode carbon anode for aluminum electrolysis, there is less carbon slag in the electrolyte, which affects the production capacity. There is almost no carbon slag removal during production, and there is no such process as carbon slag removal. The anode waste carbon anode for aluminum electrolysis control is relatively low, generally 0.05 to 0.1 times/cell day. At present, it is trending towards "zero-effect" control.

　　 The quality of the domestic pre-baked anode carbon anode for aluminum electrolysis is different from that of foreign countries due to raw materials, technology and standards. The anode has poor oxidation resistance and severe slag sloughing. Cinder removal is an important process in production. Traditional management technology believes that the use of anode waste carbon anode for aluminum electrolysis can promote the separation of carbon slag in the electrolyte, and can also supplement heat and control precipitation in the tank. Therefore, improving the quality of domestic anode carbon anode for aluminum electrolysis is a key factor in reducing anode waste carbon anode for aluminum electrolysis.
