Suspension melting furnace

The 10kg suspension melting furnace is a small equipment used for melting metals, which utilizes electromagnetic suspension technology to achieve non-contact melting of metal materials.

Working principle
Electromagnetic levitation: By generating eddy currents in metal materials through high-frequency electromagnetic fields, and utilizing the interaction between eddy currents and magnetic fields to generate levitation forces, the metal is suspended in the air.
Induction heating: Eddy currents simultaneously generate heat, heating the metal to a molten state.
main features 
Contactless melting: Avoid contact between metal and crucible, reduce pollution, suitable for high-purity material preparation.
Accurate temperature control: Accurate temperature control, suitable for temperature sensitive metal materials.
Wide applicability: It can be used for melting high melting point metals and alloys such as titanium, zirconium, tungsten, etc.
application area 
Research: Used for the study of materials science, metallurgy, and other fields.
High end manufacturing: used in industries such as aerospace and medical equipment that require high material purity.
New material development: suitable for developing new alloys and high-performance materials.
