HYDRAULIC TILTING MELTING FURNACE - FIM/CPU

These furnaces are ideal to melt precious metals. All ITALIMPIANTI ORAFI induction melting furnaces are fitted with static frequency converters.

A high efficiency of the electrical output that drastically reduces electricity consumption while maintaining the production rate thanks to frequency conversion system we have used.

The modular construction of the electric circuit board greatly simplifies maintenance operations and guarantees high reliability even in the most demanding working conditions.

The highest technical standards used to design the inductors along with the modular construction and the use of only high quality materials guarantee maximum production even in the worst conditions.

Flux concentrator

All our melting furnaces can be supplied with “Flux Concentrator” Technology.

The flux concentrator is the latest technology used for safety and power efficiency purposes in the melting industry.

Main advantages:

  • Higher density of magnetic energy in the area inside the induction coil.
  • Less time needed for the melting cycle.
  • Higher energy efficiency.
  • Higher magnetic stirring efficiency of the molten material.

 

Additional features

  • Absolute alloy homogeneity guaranteed by the medium frequency converter
  • Reduction of melting losses due to uniform temperature distribution in the molten 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.
