VACUUM MELTING FURNACE FOR PLATINUM, PALLADIUM AND ALLOYS - FIM/FPT ()

These furnaces are ideal to melt precious PGM  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.

The furnace consists of a water-cooled stainless steel chamber inside which the crucible and ingot mould/refractory flask tilt for the pouring process. A gear motor with inverter and joystick controls the tilting mechanism. A vacuum pump for high vacuum levels is also fitted on the unit along with an optical pyrometer to read the temperature.

  • Display monitoring of the working parameters of converter as tension and absorbed power;
  • Computerised alarm diagnostics for the alarms or warnings which the worker must take note of for the system to work properly. lnstructions and advice are shown on the display: ;
  • Closed ring power regulation that allows the system to absorb the set power regardless of the quantity and type of metal to melt;
  • The internal environment of the converter is conditioned by an air-water exchanger.

 

MAIN ADVANTAGES

These furnaces offer a wide array of advantages:

  • 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.
  • The converter is fitted with a centrifugal pump to recycle cooling water, fitted with a pressostat and a timer to automatically stop the pump. You require only a storage tank for demineralized water or a water-cooling plant.
  • Display monitoring of the working parameters of converter.
  • Computerized alarm diagnostics for as many as 12 alarms or warnings which the worker must take note of for the system to work properly.
  • Closed ring power regulation which allows the system to absorb the set power regardless of the quantity and type of metal to melt.
  • The internal environment of the convertor is conditioned by an air-water exchanger
