[0002] Anode carbon block is one of the important components of the electrolytic cell system, which is used as an anode to undergo oxidation-reduction reaction in electrolytic aluminum. The anode is continuously consumed, but in the high-temperature environment of the electrolytic cell filled with corrosive gases, the anode carbon block is easily oxidized and corroded. The consumed anode carbon block cannot participate in normal oxidation-reduction reaction, resulting in a shortened service life of the anode carbon block and increased production cost. To solve this problem, enterprises will apply a layer of aluminum ash-based oxidation-resistant coating on the surface of the anode carbon block.
