Retech's Vacuum Arc Remelt (VAR) Furnaces
Vacuum Arc Remelting (VAR) is a secondary melting process that is used to improve homogeneity in metal alloy ingots. This equipment can be used for reactive and refractory metals as well as high value steels.
Since 1963, Retech has enjoyed being a worldwide leader in the production of Vacuum Arc Remelt (VAR) furnaces configured for a range of capacities for producing ingots or castings, from a laboratory scale to many tons.
VAR is used for production of metal ingots that require high chemical and mechanical homogeneity. It is used on a variety of metals including various grades of stainless steel, alloy steel, titanium alloys, nickel superalloys, nitinol, zirconium, niobium, platinum, tantalum, and rhodium…among others.
Materials are processed in the VAR to remove or reduce contaminants and to allow the material to form the desired microstructure (grain structure) that will improve the performance in the desired application. Retech has primarily sold VAR equipment into the Titanium processing market so these materials would be titanium alloys. However, specialty steels often require VAR processing to increase the cleanliness and homogeneity of the ingots.
