INGOT MAKING

INDUCTION MELTING PLANT TYPE FIM/15LING

The furnace is used to produce n. 20 Au 1 kg or 2 kg ingots per hour.

A high efficiency of the electrical output that drastically reduces electricity consumption, maintaining the production rate, is obtained by the frequency conversion system 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 is fitted with two special crucibles to melt 1-2 kg of Au each. Each crucible has its own protection burner to protect the crucible and metal from oxidation during melting.The crucible is removed by a special pedal system which raises the crucibles from the botton allowing the worker to pick the up with the special pincers.After melting, the gold is then manually poured into the ingot moulds.

This special unit consists of :

• Water cooled work TABLE border=1 on which the ingot moulds are placed
• Ingot solidification control unit – fitted with photoelectric cells and timed propane gas burner

C. STATIC FREQUENCY CONVERTER

• Power output
• Working frequency
• Power-supply tension
• Power factor (cosF-i)
• Required cooling power (generator/furnace)
• Minimum water cooling capacity
• Min pressure for the cooling water pump
• Cooling water inlet temperature

: 15 kW : 10 Khz: threephase : 0.9 : 10500 Kcal/h : 20 lt/min : 3 Bars : 30° + 35°C

• The converter is fitted with a centrifugal pump to recycle the cooling water, fitted with a pressostat, thermals, fuses and a timer to automatically stop the pump. You require only a storage tank for demineralised water or a water cooling plant.
• Display monitoring of the working parameters of converter as tension and absorbed power.
• Computerised alarm diagnostics for as many as 12 alarms or warnings which the worker must take note of for the system to work properly. Instructions and adviceare shown on the display.
• 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
• Threephase power-supply transformer :
  • Nominal power: 15KVA
  • Nominal tension : depends on where the machines
  • Allowed fluctuation of the electrical mains : +/- 10%

These chilling units are ideal for all cases where it is important to keep the temperature of the cooling water within certain limits. Suggested uses are with :

• Water cooled induction melting furnaces
• Trichloroethylene degreasing machines
• Brazing belt furnaces
• Deoxidation furnaces
• Fumes condensors for hollowing and refining plants.
