Bench-top Vacuum Melt Spinning System with 15KW Power Supply - EQ-VTC-200S

0.0/5 rating (0 votes)

Description

 
EQ-VTC-200S is a benchtop vacuum melt spinning system for preparing amorphous metallic ribbons up to 2000ºC.  In this technique, metal ingots are melted via the induction heating method and then propelled by overpressurizing the crucible. A thin stream of molten is then dropped onto a fast-spinning surface of a cold copper drum. This causes rapid quenching & solidification of the molten and thus form the ribbon (< 10 mm width) of the liquid metal alloy 
    The system features an SS air-tight chamber with a front observation window. A turbo backed by a dual-stage oil pump is optional for achieving a high vacuum up to 10^-6 torr. The unit provides inlet and outlet valves for inert gas purging. This helps to protect samples from moisture or oxygen exposure during the melt spinning process. The user can also control the RPM of the drum, induction heating power, temperature, and pressure applied to the crucible. SPECIFICATIONS:

  • 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
