  1. super Audio frequency induction heating machine (SAFIH)is a specialized devices used for heating materials, typically metals, using electromagentic induction at super audio frequencies (often around 10KHZ to 50KHZ).A super audio frequency induction heating machine utilizes high-frequency electromagnetic fields to generate heat within conductive materials. Here are some key aspects

Super Audio Frequency Heating Machine (Induction heating machine)

Super audio frequency induction heating machines (10–100 kHz) provide controlled, medium-depth heating ideal for applications like surface hardening, brazing, and shrink fitting, commonly used in automotive and aerospace industries.

Technical Parameter

Super-audio Frequency machine

1. Power Output ;
Range : 10 kw to 500 kw or more
Description : Power output defines how much energy the machine can deliver to the material being heated. Higher power enables larger or denser materials to be heated faster
2. Frequency Range :
Range : 10 khz to 100 khz
Description : Frequency determines how deeply the heat penetrates the material. Lower frequencies (10–30 kHz) are ideal for deep heating, while higher frequencies (30–100 kHz) are used for surface heating.
3. Input Voltage :
Range : 380V AC to 480V AC(three phase)
Description : The input voltage depends on the model and its application. Industrial units generally require high-voltage, three-phase input.
4. Cooling System :
water-cooled : Most systems use water-cooling mechanisms to maintain the temperature of internal components such as induction coils and power electronics.
5. Duty Cycle :
Range : 80% to 100%
Description : It shows how long the machine can operate at full load without overheating. 100% duty cycle means it can run continuously.
6. Control Mode :
Manual/Automatic: Some machines offer both manual and automatic modes of operation with programmable timers or heating cycles.
7. Temperature Control :
Accuracy: ±1 to ±3°C.
Control method: Typically involves thermocouple or infrared sensors to monitor and regulate the workpiece temperature.
8. Inductor Coil Type :
Customizable coils for various workpiece shapes and sizes (helical, pancake, internal, etc.).
9. Efficiency :
Range: 85% to 95%.
Description: Shows the percentage of input energy that is converted to heat.
10. Size and Weight :
Dimensions: Varies depending on power output (for example, 800 mm × 600 mm × 1200 mm for a 30 kW machine).
Weight: Generally between 50 kg to 500 kg depending on size and power.
11. Control Interface ;
PLC-based touch panel or buttons for easy operation and monitoring of parameters like temperature, power, and time.
12. Material Compatibility :
Suitable for heating steel, stainless steel, copper, brass, aluminum, and various other conductive metals.
13. Application examples :
Forging, Brazing, Melting, Annealing Hardening, Soldering and Heat Treatment.
