Vacuum Arc Remelting Furnaces

VAR — The Process

Prior to start up, the electrode to be melted is loaded into the furnace. For specialty steels and superalloys, the electrode is previously cast in air or vacuum. For primary reactive metals like titanium, the electrode is fabricated from compacted sponge and/or scrap, or from a hearth melt process like Plasma or Electron Beam.
