Titanium producer Perryman Co. commissioned two new furnaces at its California, PA, plant, systems designed and built by Retech Systems LLC. At that time, Perryman explained it would more than double its titanium melting capacity with the addition of a new electron-beam (EB) furnace and a new vacuum arc remelt (VAR) furnace.
An electron-beam furnace uses a high-energy, electron beam under vacuum to deliver heat to the titanium or other material being melted. At Perryman, EB melting is used to produce electrodes weighing up to 12,500 lbs.
Vacuum arc remelting (VAR) is a secondary process that melts the electrodes and refines the metal alloys using an electric arc under vacuum, to produce metal ingots, which become feedstock for forging or rolling.
According to Retech Systems, the Perryman project made use of Retech’s global manufacturing capabilities as part of the SECO/Warwick Group.
