Application of Melting furnace
Intermediate Frequency Electrical Melting Furnace, also called as Induction Smelting Furnace, which converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting. It is applicable to melting, heating or insulting of steel, copper, iron, aluminum, zinc, tin, nickel silver and other ferrous, nonferrous metal. It can also be used for other heating treatment before forging, sintering and tube-bending forming in the casting and melting industries.
Intermediate Frequency Electrical Furnace Performances and Features
1. Adopt a zero-voltage scanning soft-start mode, it can be started or stopped in any case and at any time, so it has no impact on power supply.
2. Fast smelting with low production cost; Low-pollution and environment-friendly;
3. Start melting from cold furnace. Solution can be fully empty. Change molten material easily.
4. Power adjustment is flexible. Be able to adjust continuously and smoothly. Temperature is even and can be easily controlled. Less oxidation burning. Metal components is even.
5. Furnace shell is adopt aluminum alloy or steel structure, covering small area; Convenience to overturn the furnace, according to your need to adpot overturing way like electric, manual, hydraulic.
6. It can automatically adjust to match the load impedance, The equipment will always run in good working condition without adjustment of compensation capacitance, low fault rate; Power supply system has diagnostic error function that make it easy to check and maintenance.
7. Suitable for intermittent production.

Advantage of induction melting furnace:
1. With strong and durable, beautiful and generous furnace body.Especially for large capacity furnace which need the stronger steel structure .From the point of view of safety dumping has better adopt steel shell furnace.
2. Selenium steel made of magnetic yoke of the magnetic field lines generated by the induction coil has played the role of shielding emission to reduce the magnetic leakage so that it improves the efficiency and energy saving is 5%~8%.
3. The furnace cover reduces heat loss and improves the equipment safety.
Safty Protection:
• Main circuit short circuit protection
• Main circuit phase loss protection
• Main circuit phase fault protection
• SCR over-current protection
• SCR overvoltage protection
• Cooling water temperature protection
• Low water pressure protection
• Furnace leakage protection
• Intermediate frequency power failure protection
• Intermediate frequency electric furnace fault protection rate and increase the life obviously
Why Choose us:
1,Low power consumption
Large current system made of pure copper as conductive medium, the whole circuit with less resistance. Electrode arm shaped as copper-clad box type, resistance and heat can be reduced efficiently. Reasonable arrange of all conductive systems to minimize the resistance of every circuit.
2,Safety & Stability
Full set of hydraulic driving system equipped with accumulator to ensure stability of facilities in the operation process. Whist, equipments can go on the motion when there any emergency accidents happen.
3,High Power Factor
Our power factory could reach over 98%, which could greatly reduce the capacitor box quantities. However we still equip enough capacitor box quantities, which mean your furnace is much much more efficient.
4.High flexibility & Maximum simplicity of operation
HMI used in electrical automation control, interface simulates the real form of furnace, which make the operation more convenient. Mixing feedstock, charging feedstock, melting, tapping all the commands can be implemented by computer.
5.More Durable
We get 6 thyristors on the left, 8 on the right, so even if one thyristor is damaged, our furnace still could be continued use. But many other factories only get only 4 on the right,the whole equipment cannot be used anymore when one thyristor is damaged.
