Reactive VAR Furnaces (RVAR)

RVAR Furnaces for the production of reactive materials, such as titanium, being produced from low packing density material such as sponge compacts or bulk welded materials.  The low packing density electrodes requires that the furnace has extensive ram travel and volume within the crucible and head to melt the entire electrode into an ingot.  The Consarc RVAR furnace, with its column design allows the ram drive and head lift to collapse on one another minimizing the overall furnace height while maximizing the head and ram travel available.

Consarc RVAR furnaces are available in a wide array of combinations of furnace heads, melt stations, and power supplies to match production levels with an economical quantity of materials.
