7 kW Melt-spinning System with the Glove Box - VTC-200S-GB

VTC-200S-GB is a benchtop vacuum melt spinning system for preparing amorphous metallic ribbons up to 2000ºC. Air-sensitive samples can be prepared inside the glove box and transferred to the melt-spinning system without exposure to the air via a transfer tank. With a direct couple with the glove box, the sample collection process can also be completed inside a glove box. 

During melt-spinning, metal ingots are melted via induction heating and propelled by pressurized inert gas. A thin stream of the melt is cast onto a spinning copper drum. The rapid quenching and solidification process enables the alloy forms amorphous ribbons in a few seconds.

Application Notes	Material testing using melt-spinning is available, otherwise, we use NbFeB as the standard for testing before shipping Please be advised that not every material can be melt spun.  In order to achieve melt-spinning successfully,  the material melt must have a proper viscosity.  It is the customer's responsibility to find the right composition, crucible size, and power supply Ferromagnetic metals are generally responsive to induction heating. For refractory materials, e.g. materials with high melting point (>1200ºC) or low permeability (μ/μ0<100), please consider using BN crucibles with graphite casing for the best performance The equipment also can be modified into a casting and granulating furnace
