FMF-10 Compact Levitation Cold Crucible Vacuum Melting Furnace with 10KW Induction Heater and 5g Max Sample Capacity
The FMF-10 is engineered for laboratory-scale melting of small metallic and alloy samples under vacuum or low-pressure environments. It is particularly suited for developing and studying advanced magnetic alloys and metallic materials requiring ultra-high purity. The system employs a magnetic vortex levitation melting technique within a specially designed water-cooled copper crucible, which is housed inside a vacuum-sealed quartz tube to prevent contamination.
Melting is achieved by a 10KW high-frequency induction heater operating at adjustable frequencies between 50 and 300 kHz. The copper crucible dimensions are 27 mm outer diameter, 10 mm inner diameter, and 12 mm depth, capable of holding up to 5 grams of metallic material. The vacuum chamber includes a quartz tube (32 mm OD x 28 mm ID x 160 mm length) and vacuum flanges with high-temperature silicone O-rings, enabling vacuum levels down to 10-5 torr with optional molecular pump. Sample loading and unloading are facilitated by an electrically controlled bottom flange.

대표적인 적용 분야
Ideal for research and development of high-purity magnetic alloys and metallic materials requiring contamination-free melting under vacuum or low-pressure conditions. Suitable for small sample sizes up to 5 grams in materials science, metallurgy, and advanced alloy development laboratories.
구성 및 작동 안내
The system requires a continuous supply of high purity argon gas (>5N) with a pressure regulator set below 3 PSI to avoid damage to the vacuum chamber. Gas flow should be maintained below 200 SCCM. A recirculating water chiller is recommended if no external water cooling line is available. The furnace must never be heated with the gas release valve closed to prevent positive pressure buildup inside the chamber. The power control unit is separate from the induction heating unit for ease of maintenance. Safety precautions include continuous monitoring of internal pressure during operation to prevent irreparable damage.
