Induction melting is a process in which an induction furnace is used to heat a metal to its melting point. The metal to be melted is placed in a crucible.
The induction process can heat the metal directly in a ceramic crucible or in some applications utilize an intermediate susceptor such as graphite. Special applications of induction heating allow the melt to levitate and allow melting of high purity or high reactive materials without contamination. Induction melting can be done in a vacuum or under inert atmosphere for highly reactive metals. The process for induction melting of metal can be combined with casting capability to complete the melt and cast within one system.
Typical materials for Induction melting of metal include copper, gold, silver, stainless steel, brass, aluminum and other metals. Common applications include:
- Scrap re-melting
- Melting furnaces for foundries
- Melting of precious metals (gold, silver, platinum)
- Materials research and sample preparation
