Vacuum Arc Remelting Furnaces
VAR Furnaces for melting material that have already been melted and cast into electrodes that are near their full packing density. Consarc utilizes fully computerized controls to optimize reproducibility and ease of operation. Custom furnaces in laboratory scale or for the production of unusual geometric configurations are available upon request.
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
- 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 logicSingle servo motor ram drive
- Precision melt rate control using load cells
- No hydraulics – all motions are electromechanical or pneumatic
- Siemens high speed processor for Counting Drip Shorts
