Medium Frequency Machines (induction heating machines)
Uses
A Medium frequency Machine (induction heating machines) is a specialized device used for heating materials, typically metal, through electromagnetic induction. This method relies on generating an altermating magnetic field around the material to iduce eddy current, which in turn generate heat due to the electrical resistance of the material.
Power Supply
Converts standard electrial power (AC) to the required medium frequency current (typically between 1KHZ to 100 KHZ
Inductor Coil
The work coil where the material (workpiece) to be heated is placed. The alternating current in the coil creates a magnetic field in the workpiece
Water cooling system
Cooling system to cool the machine components , especially the induction coil, since induction heating generates signigicant heat
Control Unit
Control Unit allows for adjusting parameters like frequency, power level, and heating time, ensuring precise control of the heating process.

Applications
-Medium Frequency induction heating machine are Ideal
Medium frequency heating is used in various industrial applications where there is a need for fast, efficient and controlled heating of metals. The Aavrtti range (10 kilohertz to 500 kilohertz at Aamataur) is made broad, which allows for heating of a part that is either of medium size or without much heating at the same time.(Read More Induction Heating Machine)
Medium frequency melting is a process commonly used in foundries and metalworking industries to melt metals using medium-frequency induction furnaces. These furnaces operate at frequencies typically ranging between 150 Hz and 10 Khz. The Process involves electromagnetic induction to heat and melt metals efficiently.(Induction Heating Machine by Malhtora technologies)
Basic Information Medium Frequency Machine (Induction heating machines)
A medium frequency induction heating machine is commonly used for heating metal objects, including iron bars, due to its efficient and rapid heating process. Here’s an overview of how it works and its suitability for heating iron bars:
How Induction Heating Works:
Electromagnetic Induction: The induction heating process relies on Faraday’s law of electromagnetic induction. A coil generates an alternating magnetic field when an alternating current (AC) passes through it. The frequency of the AC determines the frequency of the magnetic field.
Induced Eddy Currents: When a conductive material like an iron bar is placed within the alternating magnetic field, eddy currents are induced within the bar. These circulating currents generate heat due to the electrical resistance of the material.
Heat Generation: The heat is generated internally within the iron bar rather than externally, which allows for faster and more efficient heating. In medium-frequency induction heating, the frequency typically ranges from 1 kHz to 100 kHz.>br>
Heating Iron Bars with Medium Frequency Induction:
Medium Frequency Range:
Medium-frequency induction heating is suitable for moderate-depth heating applications like heating iron bars. This frequency range is ideal for uniform heating across the surface and to some depth within the bar.
Penetration Depth:
In induction heating, the higher the frequency, the shallower the heat penetration. Medium frequency provides a good balance between surface heating and heat penetration to a moderate depth, which is useful for iron bars of varying thicknesses.
Efficiency:
Induction heating is highly efficient because it directly heats the metal, leading to minimal energy loss. It’s also fast, making it suitable for industrial processes like forging, annealing, or bending iron bars.
Applications:
Forging: Preheating iron bars before forging or shaping.
Hardening: Surface hardening of iron bars by rapidly heating and cooling the surface.
Annealing: Heating iron bars to relieve internal stresses and improve ductility.
Advantages:
Rapid Heating: Induction heating is significantly faster than conventional heating methods like furnaces.Energy Efficiency: High efficiency due to direct heating of the material.
Precise Control: Allows for precise temperature control, which is crucial in metallurgical processes.
No Direct Contact: The iron bar doesn’t need to touch the heating coil, avoiding contamination or wear on the coil.
Key Considerations:
Power and Frequency: The power of the induction heating machine should match the size and mass of the iron bar. Higher power units may be needed for larger bars.Coil Design: The induction coil should be designed for even heating of the iron bar. For long bars, multiple coils or a traveling system might be used to ensure uniform heating.
This technology is commonly used in industries where speed, efficiency, and precise control of heating are critical.
