Gold Melting furnace/Gold refining machine/Gold smelting furnacePortable gold melting furnace Operating principle of induction heating

Frequency conversion electromagnetic induction heating or induction heating for short is a method for heating metal materials by converting power frequency power supply into that of specific range based on the principle of electromagnetic induction. It is mainly applicable to the metal hot working. Heat treatment. Welding and melting. This type of heating technique is also applicable to packing industry (such as sealing of aluminum foil used in medicine and food industry), semiconductor material(such as extruded monocrystalline silicon and heated affixing metal parts for auto glass)

Basic components of induction heating system include induction coil. AC power source and work pieces, Induction coil can be fabricated into different shapes as per different heated objects. The coil is connected with the power source providing alternating current for coil. The alternating current possessed by the coil can create an alternating magnetic field passing through the work pieces to produce eddy flow as required by heating.

Advantages of induction heating equipment
1. Fast heating, wide heating
The minimum rate of heating is less than 1second (rate of heating is available for adjustment and control)

2. Comprehensive protection
It has such functions as over voltage. Over current, overheat and water shortage alarm indications as well as automatic control and protection.

3. Easy installations. Easy operation
It can be used once it is connected with power source, inductions coil as well as water supply pipe and rising pipe: It is small in size and light in weight: You can learn to operate it within several minutes.

4. High effectiveness
It has such features as uniform heating (it is applicable to adjust the spacing of the inductions coil to ensure the appropriate temperature as required by each part of work piece). Fast warming and limited oxic horizon and can guard against any waste after annealing.

5. Small size and light weight
It has a weight of only several dozens of kilograms. Of which, the limited floor space can effectively save the workshop space. Sound operational environment: It is favorable for environmental protection. Conservation of energy and safety operation. Which is free of any noise. Exhaust gas and dust.

6. Elimination of high voltage
Elimination of high voltage: It requires no step-up transformer which may produce approximately ten thousand voltages, and thus can ensure the maximum safety.

Machine power and technological characteristics.

Induction heating. Mainly through the crucible. To precious metal in an instant, then smelting. Refining, casting and other processes:
For the precious metals: Platinum, palladium, rhodium, gold, silver, copper. Steel, gold powder, sands, tin, tin slag ash all these melting point metals:
A single molten metal quantity: 1kg-50kg. A single melting time: 2-20 minutes:
The maximum furnace temperature up to 1500-2000 degrees.
Commission for the mummer of ash -like powder high up to 97 percent.
