Small Levitation Cold Crucible Vacuum Melting Furnace (40KW,20 g Max.) -- EQ-FMF-40

Please email for lead time
Item Number: EQ-FMF-40
EQ-FMF-40 is an Advanced Vacuum Float-Melting System for exploring new generation magnetic alloy and metallic materials with max. loading 20 g sample. The system uses 40KW high frequency induction heater  to cause 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..

    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.
      • The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process.
      • 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 manual carefully. Monitor and properly control the inside pressure of reaction vessel at all time during operation. Otherwise, failure of operation may result in irreversible damage to the equipment or personal injury
