induction melting furnace can strictly control the alloy composition, and has the ability of electromagnetic stirring and high vacuum degassing. Smelting and casting of nickel-based, iron-based, cobalt-based and other advanced precision alloys or high-purity metals can be performed under high vacuum conditions or under a protective atmosphere. If a graphite crucible is used, low-resistivity metals and their alloys can be melted by indirect heating, such as gold, silver, copper, aluminum, bronze, etc.
