摘要

Crucible (1) has an insert region (2) with a batch insert, a melting, homogenizing and/or refining region (3), an overflow and/or run-off region for removing the melt and an induction device for introducing a high frequency radiation into the melt region. A protection unit (10) surrounds the induction device to protect the device from high frequency radiation. Preferred Features: The protection unit is made from a metal cage, preferably a cage made from perforated metal, a metal grid or woven metal.
