VTC-200S-GB 7 kW Vacuum Melt-Spinning System with Integrated Glove Box for Air-Sensitive Amorphous Ribbon Production
The VTC-200S-GB system is engineered for the preparation of amorphous metallic ribbons through vacuum melt-spinning, reaching temperatures up to 2000ºC. This benchtop unit is particularly suited for processing air-sensitive materials, as it integrates a glove box allowing sample handling and transfer without exposure to atmospheric oxygen or moisture. The system includes a transfer tank that facilitates secure movement of samples from the glove box to the melt-spinning chamber, maintaining an inert environment throughout the process.
During operation, metal ingots are melted by a 7 kW induction heater and propelled by pressurized inert gas onto a rapidly spinning copper drum. The melt solidifies instantly upon contact, forming thin amorphous ribbons. The glove box connection allows the entire sample collection process to be completed in an oxygen- and moisture-controlled atmosphere, preserving sample integrity for sensitive alloys.
Wichtigste Merkmale
- 7 kW desktop induction heater operating at 30-80 kHz for melting alloys up to 2000ºC.
- Vacuum chamber with stainless steel construction and quartz observation window, achieving 5e-5 torr vacuum within 30 minutes.
- 200 mm diameter copper flywheel spinning up to 31 m/s (3000 RPM) with adjustable crucible-to-wheel gap (0-10 mm).
- Integrated glove box with automatic gas purification, pressure control, and HEPA filtration for oxygen and moisture levels below 1 ppm.
- Sample transfer tank and ISO160-K gate valve isolate glove box and melt-spinning system to prevent cross-contamination.
- Two quartz crucibles included for materials melting below 1200ºC; custom crucibles and graphite sheaths available.
- Siemens PLC control with touchscreen for monitoring oxygen, moisture, and pressure inside the glove box.

Typische Anwendungsbereiche
This system is ideal for research and development of amorphous metallic ribbons, especially for air-sensitive alloys requiring inert atmosphere processing. It supports rapid solidification studies, magnetic material fabrication, and alloy composition optimization under controlled vacuum and inert gas conditions.
Hinweise zur Konfiguration und zum Betrieb
The system requires an external water chiller for induction heater cooling, which is not included. A separate vacuum pumping system for melt-spinning is also necessary but sold separately. Optional accessories include high-frequency induction heaters, custom crucibles (quartz or boron nitride), graphite sheaths for refractory or low magnetic permeability materials, water-cooled or stainless steel spinning wheels, and carbon/solvent vapor filters for glove box atmosphere.
Users should verify material viscosity and melting behavior to ensure successful melt-spinning. The equipment can be adapted for casting and granulating applications. Safety precautions include proper handling of inert gases and ensuring water cooling is operational to prevent induction heater damage.
