Solid state power supply, also known as crystal or IGBT power supply, is a kind of power supply device applying modern electrical and electronic component IGBT module as key part of converter, and converts 50Hz power current into current with at different frequency band which produces strong electromagnetic field in inductor to heat metal in a very short time.

Performance and features

1. High energy and high work efficiency: integrated circuit provides visible high work and energy efficiency and saves more than 30% of energy as compared to traditional electron tube HF product, brings obvious economic benefits to customers, high price to performance ratio;

2. Compact design: volume of solid induction heating furnace with no more than 60kw of power is slightly larger than main-frame of personal computer, requires small footprint and easy for relocation;

3. Wide frequency adjustment range, high output power, and easy adjustment: frequency is adjustable between 20kHz and 90 kHz, duplex transfer, effective control of depth of quenching, and highly adaptable to load;

4. Easy installation and operation, quick start, and speed heating: available for operation by connecting power supply, induction coil and inlet pipe, enable operators to understand operation tips in several minutes, started immediately upon connection of electricity and water, uniform heating, rapid warming (in seconds), and minimum oxide layer.

5. High reliability and safety: multi-functional stepless adjustment, comprehensive protections (e.g. overpressure, overcurrent, low water level, open phase, and overheating protection) to prevent misoperation and assure personal and equipment safety, and safety is improved significantly due to absence of 10kV high voltage;

6. Automatic control and digital display of heating time: heating, holding and cooling by time-interval, available for manual/automatic cycle operation.

Knowledge For Choosing Induction Heating Equipments

Heating Type
Scope of application
 Frequency selection
Power selection
Workpiece diathermic
Heat forging and hot rolling, etc. of fastener, standard part, auto accessory, hardware tool, and twist drill.
principle:the greater the diameter,the Frequency should be lower.Such as:Φ20above,IF(10-20KHZ) Φ5-20,high Frequency (20-100KHZ) Φ5below UHF(100-500KHZ).
Select appropriate power depending on production efficiency, higher power higher speed; please consult our technician for specific information.
Heat Treatment
Annealing of shaft, gear, chain wheel, and machine tool guideway accessory wire, quenching and annealing etc. of hydraulic accessories, auto accessories, knives, scissors and clamps, stainless steel kettle.
Principle:the workpiece request more shallow hardened layer,the Frequency should be higher.Such as:1mm  below the ultrahigh-Frequency 100-500KHZ 1-2.5mm,high-Frequency more than20-100KHZ 2.5mm,IF 1-20KHZ.
Comprehensive consideration shall be made in combination with workpiece shape, quenching mode and hardness, quench-hardened case, material and other elements.
Brazing head,lathe toorl,reamer,milling cutter,drill bits,and stainless steel bottom of the pot,such as the hybridwelding of different materials.
Principle:the greater the volume of welding, frequency should be reduced more. Smallerthan 30*30*30of the tool,to be used in high frequency,Prince 30*30*30,frequency applications.
According to specified body workpiece shape,materials,solder,etc to the set.
Gold,silver,copper,precious metals such as lead.
Intermediate-frequency,optional high-frequency small capacity.
 According to a furnace and the production efficiency of the concrete.
According to the production speed,material,temperature.
