High Frequency Induction Heating Equipment

  • Model    SN - 2*A
  • Power    25 KW
  • Frequency    30-80 KHZ
  • Voltage    Three-phase 380V 50/60Hz
  • Application    Small hardware heating applications, tool welding, diamond tool welding, small parts heat treatment, precious metals such as gold, silver and a small amount of melting, indicating heat treatment, etc


The principle of induction heating:

  • After the induction heating equipment outputs a strong alternating frequency current, a strong alternating magnetic field is generated through the induction coil
  • Under the action of the magnetic field, an eddy current is formed on the surface of the heated workpiece, which quickly heats the workpiece

A wide range of uses for induction heating equipment:

  • Welding (brazing, silver soldering, copper soldering)
  • Heat treatment (surface quenching)
  • Annealing (tempering, quenching and tempering)
  • Smelting (refining)
  • Heating (diathermy, hot forging, hot forming)
  • Thermal fit, thermal induction

Heating type Scope of application Frequency selection Power selection
Composite welding of drill bits, turning tools,
reamers, milling cutters, drill bits, etc. and
different materials for stainless steel pot bottoms.
Principle: The larger the welding volume,
the lower the frequency should be. For tools
with a volume smaller than 30*30*30, high
frequency can be used; if it is larger than
30*30*30, medium frequency can be used.
Principle: The larger the diameter of the
workpiece, the lower the frequency should be.
It depends on the specific workpiece
shape, material, solder, etc.
Fasteners, standard parts, auto parts, hardware
tools, copper rods, hot upsetting and hot rolling
of twist drills, etc.
Above φ20, intermediate frequency (1-20KHZ)
φ5-20, high frequency (20-100KHZ)
Below φ5, UHF (100-500KHZ)
Select the appropriate power according to the
production efficiency. The higher the power,
the faster the speed. Consult the company’s
technical staff for details.
Quenching of shafts, gears, sprockets,
machine tool guide rail accessories, etc.
Principle: The shallower the hardened
layer is required for the workpiece,
the higher the frequency should be.
Ultra high 100-500KHZ below 1mm
1-2.5mm Super Audio 20-100KHZ
IF 1-20KHZ above 2.5mm;
Considering the workpiece shape, quenching
method, quenching hardness, hardened layer
requirements and materials etc., you can consult
the company’s technical personnel for details.
Metal wire and pipe annealing, hydraulic fittings,
auto fittings, knife scissors, stainless steel pot
annealing, etc.
Combined with the comprehensive consideration of workpiece
annealing requirements, annealing speed and materials, please
consult the company’s technical personnel for details.
It is mainly suitable for melting of steel, iron,
copper, aluminum, zinc and various precious
metals such as gold and silver.
Intermediate frequency;
small capacity optional high frequency
It depends on the furnace and
production efficiency.
Heating coating of aluminum-plastic pipes,
steel-plastic pipes, cables and wires:
aluminum drop seals for food, beverage,
and pharmaceutical industries.
On a case-by-case basis Depends on production speed,
material, temperature.
