[0002] Anode busbar is the electrode wire connected to the positive pole of the power supply in the electrolytic cell, and it is an important part of the centralized power supply system. In the aluminum electrolysis process, the anode busbar leads the direct current into the electrolytic cell, so that the aluminum ions in the electrolytic cell are oxidized to produce metallic aluminum. The anode busbar is usually made of cast aluminum busbar to reduce the busbar current density, reduce the busbar voltage drop, and reduce the cost. In some special-shaped connections, the cast aluminum busbar may be welded with a rolled aluminum plate.

[0003] The anode busbar is usually made of cast aluminum busbar. This is because aluminum has good electrical conductivity and corrosion resistance, which can meet the requirements of current transmission and corrosion resistance of the electrolytic cell. At the same time, the cast aluminum busbar also has high strength and toughness, which can withstand mechanical stress and thermal stress in the electrolysis process. By pouring the molten aluminum into the pre-prepared mold, casting is carried out. After casting is completed, the casting needs to be cooled. During the cooling process, the cooling speed and cooling time need to be controlled to avoid cracks and deformation of the casting. However, during the casting process, as the molten aluminum continues to pour into the mold, the temperature of the molten aluminum that first enters the mold decreases over time, eventually leading to the occurrence of sand eyes or casting defects in the cast anode busbar.

[0008] Further, the upper mold is provided with a pouring opening and an air outlet.

[0009] Further, the top sides of the lower mold are inserted into the bottom of the fixed upper plate, the bottom of the fixed upper plate is inserted into the top sides of the lower mold, and the sealing property between the upper mold and the lower mold can be further improved.

[0010] Further, the circulating pipeline is made of stainless steel.

[0011] Further, the outer side of the circulating pipeline is sprayed with a heat-conducting coating, and the heat-conducting coating can improve the heat conduction effect of the circulating liquid in the circulating pipeline.
