The pouring port is usually equipped with a corresponding sealing device, such as a pouring port cover, to ensure that the molten aluminum does not leak during transportation, and to prevent external air from entering the ladle and affecting the quality of the molten aluminum. In addition, in order to ensure safety and normal use, the pouring port may also be provided with a pressure relief device and other accessories to prevent the ladle from being dangerous due to excessive pressure.
