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.
