Levitation melting crucibles
摘要:
Disclosed is a levitation melting crucible which can facilitate penetration of magnetism into the crucible and which can prevent a molten metal from being contaminated by an insulating material. The levitation melting crucible comprises a cylindrical main body (12) having a closed bottom, a plurality of slits (14) defined vertically in the circumferential wall of the main body (12) to open inward and outward at predetermined intervals in the circumferential direction and an insulating material (18) filled in each of the slits (14); wherein each slit (14) is designed to have an inner opening width smaller than its outer opening width, with respect to the radius of the main body (12), for example, 1.5 A > B.
