The highest temperature for an induction furnace is not determined by the furnace itself, but by the refractories and materials used to contain the heated or melted material.
In open air, the highest temperature typically reached is about 3300°F for a platinum melt.
However, the melting point of steel, for example, is up to 1370 degrees Celsius (2500°F).
To reach such high temperatures, a high-quality induction melting furnace is required.
What is the highest temperature for an induction furnace? (4 Key Points)
1. How Induction Furnaces Work
Induction furnaces use electromagnetic induction to generate electric current inside the material to be heated.
The energy of these eddy currents is used for heating purposes.
The induction power supply can reach temperatures up to 2000℃.
The workpiece is placed in an inductor wound with a hollow copper tube.
After introducing the intermediate frequency or high-frequency alternating current, the induced current of the same frequency is formed on the surface of the workpiece.
The surface of the part is rapidly heated, reaching temperatures of 800~1000 degrees in a few seconds.
2. Heating and Melting in Induction Furnaces
Under the action of the alternating electromagnetic field in the induction furnace, eddy currents are generated inside the material to achieve the effect of heating or melting.
The stirring effect of this alternating magnetic field ensures a relatively uniform composition and temperature of the material in the furnace.
The forging heating temperature can reach 1250°C.
The melting temperature can reach 1650°C.
3. Factors Affecting the Highest Temperature
Overall, the highest temperature for an induction furnace depends on the specific materials being heated or melted and the refractories used.
Temperatures of up to 3300°F for a platinum melt and 1370 degrees Celsius (2500°F) for steel can be achieved with the right induction melting furnace.
