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.
Features
- Coaxial current furnace design to reduce magnetic stirring within the solidifying ingot
- X-Y electrode positioning to center the electrode and improve ingot quality
- Rotary Piston or Dry Screw Pump vacuum systems available
- Closed loop economizer cooling system or recirculating crucible water circuit
- Fully automated controls from start-up through completion of hot top
- Full suite of safety features including argon gas backfill, reasealing overpressure relief valves and PLC safety logic
- Single servo motor ram drive
- Precision melt rate control using load cells
- No hydraulics – all motions are electromechanical or pneumatic
- Stirring coils integrated into water jacket for process control
