Vacuum Arc Remelting Furnaces

Vacuum Arc Remelting Furnaces

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.

Coaxial current furnace design to reduce magnetic stirring within the solidifying ingot
X-Y electrode positioning to centre the electrode and improve ingot quality
