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 in an axial direction into a space enclosed by an induction coil comprising a plurality of coli helices for melting material to be melted, wherein the vessel contains the material to be melted at least after inserting the vessel into the space;heating the material in the vessel to form a molten material by supplying a power to the induction coil; androtating the vessel to pour the molten material into an inlet port of a casting device,wherein the induction coil is located in a vicinity of the inlet port and non-movable with respect to the inlet port,wherein the casting device is configured to perform horizontal casting of a bulk solidifying amorphous alloy. 2. The method of claim 1, wherein the vessel is configured for tilt pouring the molten bulk solidifying amorphous alloy 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 contacting the induction coil. 4. The method of claim 1, further comprising rotating the vessel in a direction perpendicular to the axial direction of the plurality of coil helices. 5. The method of claim 1, further comprising rotating the vessel in a direction parallel to the axial direction of the plurality of coil helices. 6. The method of claim 1, further comprising turning off the power supplied to the induction coil;withdrawing the vessel from the plurality of coil helices; andreceiving a second material in the vessel to melt and casting the second material. 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 to be melted 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 the axial direction is a horizontal direction. 12. A method comprising: receiving a meltable material for melting therein in a vessel;melting the meltable material in the vessel via application of an induction field by an induction heating structure;after melting, tilting the vessel to pour the molten material into an inlet port of a cold chamber casting device; andmoving the molten material from the cold chamber into a mold for molding the molten material using a plunger,wherein the induction heating structure is non-movable with respect to the inlet port, wherein the vessel is positioned adjacent to the induction heating structure during application of the induction field, wherein the vessel is configured to tilt about an axis relative to the induction heating structure, and wherein the vessel is further aligned with the inlet port of the cold chamber casting device 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 inserting a vessel in an axial direction into a space enclosed by the induction heating structure before the melting of the meltable material. 17. A method comprising: receiving a material for melting 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 is non-movable with respect to the inlet port and has a hollow section for receiving the vessel;wherein the vessel is moveable relative to the hollow section of the induction coil, andwherein the casting device is provided under the induction coil. 18. The method according to claim 17, wherein the vessel is configured to move in a substantially horizontal direction relative to the hollow section of the induction coil, and wherein the method further comprises moving the vessel in the substantially horizontal direction and into the hollow section. 19. The method according to claim 17, wherein the vessel is further configured to rotate relative to the induction coil to move the molten material into the inlet port, and 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 is moved, wherein the passage comprises a gap between adjacent turns of the induction coil, and wherein the inlet port of the casting device is aligned with the passage.
