Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis equipment, and more specifically, to a mold for two-port casting in aluminum electrolysis. Background Art

[0002] The two-port casting mold in the process of electrolytic aluminum is mainly used for casting aluminum electrolytic cells. Its mold structure is designed with two ports, which is convenient for pouring and removing castings from top and bottom. In an aluminum electrolytic cell, molten aluminum is introduced through the gate of the mold. Therefore, the casting mold needs to ensure that the molten aluminum can flow smoothly and maintain the uniformity and integrity of the casting. After casting is completed, the casting needs to be removed from the mold, or the mold needs to be removed from the surface of the casting.

[0003] However, the traditional two-port casting mold is heavy and immovable. After casting is completed, it is very difficult to remove the mold. And after use, the inside of the mold needs to be regularly cleaned and inspected to ensure there is no residue and wear, so as to extend the service life of the mold. However, the traditional two-port casting mold is mostly an integrally formed square structure, which is difficult to complete the work of fully removing slag and cleaning smoothly, resulting in problems such as difficult later maintenance and short service life of the mold.
