Product Description
Copper crucibles for VAR furnace vacuum arc remelting
furnace
VAR is used most frequently in high value applications. Because it
is both time consuming and expensive, a majority of commercial
alloys do not employ the process. Nickel, titanium, and specialty
steels are materials most often processed with this method. The
conventional path for production of Titanium alloys includes
single, double or even triple VAR processing.[2] Use of this
technique over traditional methods presents several advantages:
The solidification rate of molten material can be tightly
controlled. This allows a high degree of control over the
microstructure as well as the ability to minimize segregation
The gases dissolved in liquid metal during melting metals in open
furnaces, such as nitrogen, oxygen and hydrogen are considered to
be detrimental to the majority of steels and alloys. Under vacuum
conditions these gases escape from liquid metal to the vacuum
chamber.
Elements with high vapor pressure such as oxygen, carbon, sulfur,
and magnesium (frequently contaminants) are lowered in
concentration.
Centerline porosity and segregation are eliminated.
