Description:

The furnace is used to produce no. 20 Au ingots 1 Kg. Each one 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.

A. MELTING FURNACE FOR 1 KG INGOTS

The furnace is fitted with two special crucibles to melt 1 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 1 Kg ingot moulds.
The FIM15LING can produce 20 ingots every hour, each one weighing 1 kg

B. INGOT SOLIDIFICATION CONTROL UNIT

This special unit consists of :
· Water cooled work table 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 : 15 kW
Working frequency : 10 Khz
Power-supply tension : threephase
Power factor (cosF-i) : 0.9
Required cooling power (generator/furnace) : 10500 Kcal/h
Minimum water cooling capacity : 20 lt/min
Min pressure for the cooling water pump : 3 Bars
Cooling water inlet temperature : 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 advice are 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%
