VTC-200S Benchtop Vacuum Melt Spinning System with 15KW Induction Heating, Up to 2000°C, 200mm Copper Drum
The VTC-200S is engineered for laboratory-scale production of amorphous metallic ribbons by rapidly solidifying molten metal alloys. It melts metal ingots using a high-frequency induction heating system capable of reaching temperatures up to 2000°C. The molten metal is then propelled through a crucible orifice onto a fast-rotating copper drum, where rapid quenching forms thin ribbons typically less than 10 mm wide.
This benchtop system incorporates a stainless steel vacuum chamber with a quartz observation window, allowing visual monitoring during processing. It supports vacuum levels down to 5 x 10-5 torr when equipped with an optional turbopump backed by a dual-stage oil pump. Inert gas purging is facilitated through dedicated inlet and outlet valves to protect samples from oxidation or moisture exposure.

Typische Anwendungsbereiche
The VTC-200S is ideal for research and development of metallic glasses and amorphous alloys by melt spinning. It supports processing of ferromagnetic metals and refractory materials when used with appropriate crucibles. The system can also be adapted for vacuum casting and granulating tasks.
Hinweise zur Konfiguration und zum Betrieb
Water cooling is required for the induction heater but the water chiller is not included. Optional accessories include turbopump stations, glovebox integration for air-sensitive materials, customized crucibles (quartz or boron nitride), graphite casing assemblies for refractory metals, and water-cooled copper drums. Users should verify material viscosity and melting characteristics to ensure successful melt spinning.
