Vacuum Induction Melting Furnaces MODEL FMI-1, FMI-2
Since the first unit was produced in 1957, ULVAC has delivered over 200 vacuum induction melting furnaces to customers in Japan and around the world. These furnaces are contributing to a wide range of industry applications such as specialized steel, electronics materials and new materials. They have been used in developing new technologies such as high-vacuum degassing and refining using cryopanels, and multi-element alloys created by single-direction agitation systems. ULVAC can also provide equipment lines and production technology for rare-earth magnet manufacturing.
Features
- Cryopanels create outstanding degassing effect.
- Large volumes of activated metal can be added and controlled.
- Outstanding ingot cleaning
- Single-direction agitation creates outstanding component uniformity
- Rapid heating, for outstanding operability
- Selectable casting type:black and strip casting
applications
- Fe-base alloys : Mechanical tools (hob cutters, pinions, cutting tools), dies, bearing steel
- Rare-earth metals : Magnets (Nd-Fe-B, Sm-Co)
- Ti alloys : Shape-memory alloys, hydrogen-absorbing alloys
- Precious metals: Bonding wires, Au, Pt, thermocouples, electric contact materials, dental products, ornaments
- Ni-base alloys : Heat-resistant steel, corrosion-resistant materials, electrical part materials, permalloys
- Al : Bonding wires, lead frames, sputter targets
- Cu : Electric contact materials, lead frames
- Cr : Sputter targets
