Description

Technical Field

[0001] The present invention relates to the technical field of metal smelting, and particularly to a crucible forming device and a crucible forming method. Background Art

[0002] Superalloys and metallic materials are key structural materials indispensable for aviation, aerospace, energy, nuclear industry, petrochemical industry, national defense weaponry, and national economic construction. Superalloys and metallic materials need to use crucibles during smelting; however, during industrial production, usually after vacuum smelting 3 - 5 furnaces, new crucibles need to be replaced to ensure the purity of the smelted materials.

[0003] Since the size of commercial crucibles is smaller than the size of the smelting equipment coil (such as a vacuum furnace coil), currently, after placing a new crucible on the smelting equipment, the new crucible needs to be formed on the smelting equipment (that is, adding oxide filling sand between the new crucible and the vacuum furnace coil to prevent the crucible from shaking). After the crucible forming is completed, the smelting of metallic materials can be carried out.

[0004] However, when forming the crucible, it takes 2 days to sinter and bake the moisture in the filling sand, which makes the time for replacing the crucible on the smelting equipment long, delays the smelting production, and thus reduces the production efficiency of superalloys and metallic materials.
