Description:

FIMFPt Technical Specifications: VACUUM MELTING FURNACE TYPE FIM/FPt The furnace is used to melt platinum, palladium and dental alloys with a final purity containing less than 10 ppm of oxygen. The ingots or rods produced in these melting units can be directly rolled down without hammering. All ITALIMPIANTI ORAFI induction melting furnaces are fitted with static medium frequency converters (from 4 to 15 Khz). A highly efficient electrical output that drastically reduces electricity consumption while maintaining the production rate is obtained thanks to the frequency conversion system. The modular construction of the circuit boards greatly simplifies maintenance operations and guarantees high reliability even in the most demanding working conditions. Technical Data of the furnace The furnace consists of a water-cooled stainless steel chamber inside which the crucible and ingot mould tilt for the pouring process. The tilting mechanism is controlled by a gear motor with inverter and joystick. Double stage, rotating blade, oil bath vacuum pump (LEYBOLD VACUUM TRIVAC B - Mod. D65B) with gas ballast. Also fitted with an oleopneumatic valve as protection against vacuum losses and oil eddy. Nominal pump speed : 75 m3/h Actual pump speed : 65 m3/h Final partial pressure without ballast : <1 x 10-4 mbar Final total pressure with ballast : < 5 x 10-3 mbar Water vapour tolerance : 40 mbar Oil tank capacity : 2.0/3.3 lt Level of protection : IP54 Lubricating oil : N62 Connections DN 40 KF Discharge filter to oil steam damp Three phase 230/440 V 50 Hz 2.2 kW moto High precision digital pressure switch (SMC serie ZSE60F) for vacuum and low pressure readings Nominal pressure range : -100 to 100 Kpa (-1 to 1 bar) Display resolution : 0.1 Kpa (0.001 bar) Average response time : < 2.5 ms Level of protection : IP65 Optical pyrometer (LAND infrared - UNO Fibroptic Thermometer - Mod. U1 800/2600C-L) Temperature range : from 800 to 2600?C Wave length : 1 ?m Average response time : from 5 ms to 5 s (regulable) Emissivita : from 0.10 to 1.00 (regulable) Nominal field range : 75:1 Repeatability : 2?C / 4?F Level of protection : IP65 High precision digital vacuum gauge ( Leybold Thermovac - Transmitter TTR90 ) for vacuum readings + Display One Reading range : from 5 x10-4 to 1000 mbar Measuring principle : thermal conductivity (Pirani) Average response time : 50 ms Level of protection : IP40 Maximum capacity of the crucible : 8 kg Pt or 3 kg of stainless steel. Melting time : < 20 minutes Possibility to rapidly change the crucible in order to melt different alloys Dimensions of the furnace : 780x900x1650 mm (LxWxH) PLC Protective atmosphere The melting, homogenization and casting processes are done in a protective atmosphere created by an inert gas (either argon or nitrogen/hydrogen 90-10). Technical data of the converter Power output : 20 kW Working frequency : 15 Khz Power-supply tension : threephase Power factor (cosF-i) : 0.9 Required cooling power (generator/furnace) : 12000 Kcal/h Minimum water cooling capacity : 23 lt/min Min pressure for the cooling water pump : 3 Bars Cooling water inlet temperature : 30? + 35?C Dimensions of the converter : 650x670x1370 mm Other features The converter is fitted with a centrifugal pump to recycle the cooling water, a pressostat, thermal relays, fuses and a timer to automatically stop the pump. The converter working parameters are displayed for constant monitoring Computerised alarm diagnostics The internal environment of the convertor is conditioned by an air-water exchanger Threephase power-supply transformer : Nominal power: 25 KVA Short melting times and precise temperature readings Homogeneity of the alloys Minimum presence of oxygen in the ingots (< 10 ppm) Can be used to produce sheet and wire Easy maintenance operations Joystick pouring control High vacuum level : 1 x10-4 bar Advanced diagnostic software Process repeatability Process features Temperature measurement : By an infrared optical pyrometer that reads metal emissivity Protective atmosphere : Melting, homogenisation and pouring operations can be carried out either under vacuum or in a protective atmosphere Medium Frequency Generator : All of our melting furnaces work at medium frequency, the inductive currents that heat up the alloy automatically stir it as well. The result is complete homogeneity of the final product. This also avoids prealloying in a separate melter. Solidification : After pouring is over, an inert gas flows into the melting chamber to protect the metal from oxidation during the solidification process. Cooling : After the preset solidification time is up, the melting chamber is depressurized, the ingot is removed and subsequently cooled in water. This is the menu where all the working parameters are displayed for references during the melting process. OUTPUT V : This is the power output on the melting coil, in Volts TEMPERATURE : This is the temperature of the metal as read by the optical pyrometer PRESSURE : This is the value of the pressure inside the chamber ROT. SPEED : This is the rotation speed in percentage of the melting box inside the chamber. POWER OUTPUT : This is the power output on the melting coil, in kW. START CYCLE : Press this button to start the melting cycle RESET CYCLE : Press this button to stop the melting cycle and reset the machine. Additional Photos:
