Various embodiments provide systems and methods for casting amorphous alloys. Exemplary casting system may include an insertable and rotatable vessel configured in a non-movable induction heating structure for melting amorphous alloys to form molten materials in the vessel. While the molten materials remain heated, the vessel may be rotated to pour the molten materials into a casting device for casting them into articles.

1. A method comprising: inserting a vessel into a space at least partially enclosed by an induction coil comprising a plurality of coil helices for melting material, wherein the vessel contains the material at least after the vessel has been inserted into the space;heating the material in the vessel
1. A method comprising: inserting a vessel into a space at least partially enclosed by an induction coil comprising a plurality of coil helices for melting material, wherein the vessel contains the material at least after the vessel has been inserted into the space;heating the material in the vessel to form a molten material by supplying power to the induction coil; androtating the vessel, within the space and relative to the induction coil, to pour the molten material into an inlet port of a casting device,wherein the casting device is configured to perform casting of a bulk solidifying amorphous alloy. 2. The method of claim 1, wherein the vessel is configured for tilt pouring the molten material from the vessel into the inlet port of the casting device, and wherein the method further comprises tilt pouring the molten material into the inlet port. 3. The method of claim 1, wherein the molten material is poured without the molten material contacting the induction coil. 4. The method of claim 1, further comprising rotating the vessel in a direction perpendicular to an axial direction of the plurality of coil helices. 5. The method of claim 1, further comprising rotating the vessel in a direction parallel to an axial direction of the plurality of coil helices. 6. The method of claim 1, further comprising: ceasing to supply power to the induction coil;withdrawing the vessel from the space; andreceiving a subsequent charge of material in the vessel;heating the subsequent charge of material in the vessel to form a subsequent molten material by supplying power to the induction coil; androtating the vessel, within the space and relative to the induction coil, to pour the subsequent molten material into the inlet port of the casting device. 7. The method of claim 1, further comprising casting the molten material into BMG articles in the casting device, wherein the BMG articles are formed of a Zr-based, Fe-based, Ti-based, Pt-based, Pd-based, gold-based, silver-based, copper-based, Ni-based, Al-based, Mo-based, Co-based alloy, or combinations thereof. 8. The method of claim 1, wherein the inserting the vessel comprises at least partially inserting the vessel into the space. 9. The method of claim 1, further comprising transferring the material into the vessel from a material input station before inserting the vessel into the space, wherein the material input station stores and/or prepares the material for transfer into the vessel. 10. The method of claim 1, wherein the rotating the vessel comprises rotating a mechanical shaft or handle. 11. The method of claim 1, wherein inserting the vessel into the space includes moving the vessel along a horizontal direction. 12. A method comprising: receiving a material in a vessel;melting the material in the vessel via application of an induction field by an induction heating structure;after melting the material, tilting the vessel, relative to the induction heating structure, to pour the molten material into an inlet port of a cold chamber; andmoving the molten material from the cold chamber into a mold, using a plunger, for molding the molten material,wherein: the vessel is positioned adjacent to the induction heating structure during application of the induction field, and the vessel is further aligned with the inlet port of the cold chamber for receipt of molten material upon tilting of the vessel. 13. The method according to claim 12, wherein the vessel further comprises one or more temperature regulating channels, and wherein the method further comprises: circulating a fluid in the one or more temperature regulating channels to regulate a temperature of the vessel during the application of the induction field. 14. The method according to claim 12, wherein the vessel and induction heating structure are positioned along a horizontal axis, and wherein the vessel and induction heating structure are disposed over the cold chamber. 15. The method according to claim 12, further comprising molding the material into a BMG part. 16. The method according to claim 12, further comprising, before melting the material, inserting the vessel in an axial direction into a space that is at least partially enclosed by the induction heating structure. 17. A method comprising: receiving a material in a vessel;melting the material in the vessel using an induction coil;flowing fluid in temperature regulating channels in the vessel for regulating a temperature of the vessel during melting of the material; andmoving the molten material from the vessel and into an inlet port of a casting device;wherein: the induction coil has a hollow section for receiving at least a portion of the vessel,the vessel is rotatable relative to the induction coil, andthe casting device is positioned under the induction coil. 18. The method according to claim 17, wherein the vessel is configured to move in a substantially horizontal direction, the method further comprising moving the vessel in the substantially horizontal direction and into the hollow section prior to melting the material in the vessel. 19. The method according to claim 17, wherein the moving the molten material comprises rotating the vessel relative to the induction coil. 20. The method according to claim 17, wherein: the induction coil has passage through which molten material passes when the molten material is moved from the vessel and into the inlet port, the passage comprises a gap between adjacent turns of the induction coil, and the inlet port of the casting device is aligned with the passage.
