Levitation Cold Crucible Vacuum Melting Furnace (50 g Max) - EQ-FMF-40

Please email for lead time

Product Options

EQ-FMF-40 is an Advanced Vacuum Float-Melting System for exploring new generation magnetic alloy and metallic materials with max. loading 50 g sample. The system uses a 40KW high-frequency induction heater to cause a metallic sample to float during melting by magnetic vortex within a special designed water-cold copper crucible placed inside a vacuum-sealed quartz tube. Therefore, it can produce extra high purity Ferro or magnetic alloy without any contamination.
Induction Heater
  • Working Voltage: AC 208-240V, 3 phases, 50/60Hz, 40 kW.
  • Working Current: 10-100 Amp
  • Output Frequency: 50-200 kHz non-adjustable
  • Max. Output Power: 40KW
  • Electrically driven crucible holder for easy sample loading
  • Cooling Water Requirement: pressure ≥ 0.3Mpa, water flow rate ≥40 L/min
  • Max. Load: < 50g (density refers to SS 304)
Copper Crucible
  • Water-cooled crucible dimensions: Φ26mm(ID) x 50mm(H)
  • Manipulating scoop for sample flip-over under Ar.

Cooling Water &
Working Gas
Quartz Tube
  • Φ50mm(ID) x 260mm(L)
  • One pair of Vacuum Flanges with double high-temperature silicon O-rings
  • Max. Vacuum Pressure:
  • The top flange is hinged for easy sample loading 
  • The bottom flange can be controlled automatically for easy sample loading
Temperature Monitor (Optional)

  • One optional IR pyrometer (450-2000°C) for temperature reading and calibration. 
  • IR pyrometer shares the same port with the manipulating scoop (use only one function each time)
Secondary Material Feeder (Optional)
  • An optional secondary material doping system is available at an extra cost. 
  • Designed for low-melting-point and volatile solids, such as P, As, Te, Sn. 
Vacuum Pump
    • One heavy-duty mechanical pump with exhaust filter is included, and place inside the mobile case.
    • KF25 adapter, bellow, and valve are included for immediate use
    • Turbopump is available upon request at extra cost
    Compliance NRTL or CSA Certification is available upon request at an extra cost

    Warranty One Year limited warranty with lifetime support
    Application Notes
    • WARNING:
    • The flow rate of gases should be limited to < 200 SCCM (200 ml/min)
    • The Melting System are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 psi. Gas build-up with pressure levels exceeding over 3 PSI may cause irreversible damage to the furnace chamber.  
      • A pressure regulator must be installed on your input gas tank
      • The output gas pressure must be set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition. 
      • Never heat the furnace while the gas release valve is closed, and a positive pressure condition exists within the furnace chamber.
      • Open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
    • Attention: 
      Understand the standard procedure for vacuum melting and inert gas melting prior to operation. Read the manual carefully. Monitor and properly control the inside pressure of the reaction vessel at all time during operation. Otherwise, failure of operation may result in irreversible damage to the equipment or personal injury
