Patent ID: 11338361

Abstract:
The present disclosure discloses a shell mold chamber, a foundry furnace and a method for casting single crystal, fine crystal and non-crystal, which employ the technique of asynchronous-curving supercooling, and belongs to the technical field of precise casting apparatuses. Such a three-function foundry furnace includes a heating coil winding, a first thermal-shield assembly, a first superconducting coil, a second thermal-shield assembly and a second superconducting coil; and the first superconducting coil is provided at an inside of the first thermal-shield assembly, and the second superconducting coil is provided at an inside of the second thermal-shield assembly; and directions of a magnetic field generated by the first superconducting coil and a magnetic field generated by the second superconducting coil are opposite; and the first superconducting coil and the heating coil winding form a forward-directional static-magnetic-field heating zone, and the second superconducting coil forms a reverse-directional static-magnetic-field zone.
