Ambrell sold an EKOHEAT 45-kW/100-kHz induction heating system to a large university for superalloy research. The application involvesmelting up to 20 grams of tungsten to 3500°C (6332°F) in a cold crucible. A cold crucible involves levitation and requires virtually no contact between the crucible and melting bath. This method maximizes the purity of the melt. The university, which had previously used Ambrell induction heating systems for research applications, purchased this system because they needed to melt larger batches.
