Coreless and Vacuum Induction Melting

The heart of a coreless induction furnace is the coil, which consists of a hollow section of heavy-duty, high-conductivity copper tubing wound into a helical coil. The inside of the furnace is lined with refractory, usually a dry-vibe material. The diameter can vary depending on need.

Vacuum induction melting (VIM) uses currents within a vacuum to melt metal. VIM involves placing a coreless induction furnace into a vacuum chamber. The melting and casting operations are carried out at low pressures to control the entire alloy chemistry process. HWI offers high-fired magnesite brick, such as MAGNEL HF® US, because it is compatible with any oxides formed during melting. CORAL® BP brick is used as backup lining to MAGNEL HF® US brick due to its low thermal conductivity and insulating properties.
