Furnaces for Melting type FIM/NT (Manual Extraction)

  • 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, zirconia 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. Alarm messages appear on the display along with trouble-shooting guide lines.
  • Automatic turn-off function for the furnace and cooling plant if not used for a certain amount of time (useful at the end of the working day)
  • 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 larger furnaces. This system greatly reduces maintenance operations on these plants.
