- Absolute alloy homogeneity guaranteed by the medium frequency converter
- Reduction of melting losses due to uniform temperature distribution on the melting material. This avoids the ‘skin effect’ typical of high frequency converters
- Better malleability of the alloys allowing for considerable section reductions without annealing
- Possibility to use different types of crucibles including graphite, clay-graphite, silicon carbide, etc.
- Automatic temperature control by immersion thermocouple or optical pyrometer
- Automatic power control regardless of quantity or type of metal
- Computerised alarm diagnostics available in four languages with trouble-shooting guide lines.
- Automatic turn-off function for the furnace and cooling plant if not used for a certain amount of time
- Pouring can be done by manual extraction of the crucible, tilting by handwheel or hydraulic tilting
- A closed cycle deionization system for cooling water is available as a standard feature on the larger furnaces. This system greatly reduces maintenance operations on these plants.
