Application of Induction 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.
Advantages:
1) Constant power output, speedy melting, good electricity saving efficiency.
2) Zero-voltage sweep-frequency style start, adapts to requirement of frequently start.
3) Comprehensive protection functions, such as overcurrency protection, overvoltage protection, current-limiting protection, voltage-limiting, water-break protection, and default protection, equipment runs reliably under premise of melting speed guarantee.
4) Easy to operate, suitable for all casting process.
5) Aluminum Shell, lower in purchase cost.
Safety 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

Product Details:
Spare part 1:Thyristor
Brand: TECHSEM Group and CSR Group, the above two companies are leading thyristor manufacturing industry in China
Function: Stable, have strong ability to resist strong current, durable, not easy to damage
Spare part 2:Control circuit board
Brand: Hengyang Furnace, developed by our own R&D Team
Function: Double tested before production, carefully checking, have a great control on the quality, every customer comment its stablility.
Spare part 3:Induction coils
Induction coil installs in the central of the furnace, it has spiral body with rectangular empty brass circle around, the pipe center should be cooled with water. Copper bar outside induction coil will connect with water-cooling cable. The lining closes to induction coil, which made by burden, the method you can find in related parts below.
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.
