Processes

Vacuum and Controlled Atmosphere Melting

For advanced metals of many types — including super alloys such as nickel titanium — the industry standard is to melt and re-melt in a vacuum. This controlled atmosphere process protects the molten metal from multiple potential impurities, making the end product suitable for advanced applications in aerospace, medical devices, and other industries.

THE CREATION and casting of superalloys, as well as many other advanced and reactive metals, requires sophisticated vacuum or controlled atmosphere melting and remelting systems. Inductotherm Group companies design and manufacture Consarc brand systems for a variety of industries all around the world.

Vacuum and Controlled Atmosphere Melting

Electromagnetic Cold Crucible (EMCC)

Electromagnetic Cold Crucible (EMCC)

Electromagnetic Cold Crucible (EMCC) is an innovative process utilizing a segmented water-cooled copper crucible for refractory-free induction melting within a vacuum or controlled atmosphere. Melting in a water-cooled copper crucible eliminates the possibility of contamination from the fused silica solar crucible. The copper crucible is made up of water-cooled segments or “fingers.” The magnetic field ...
