Annealing heating element in steel

INDUCTION - Heat treatment

Annealing of steel heating element with induction heating: speed, uniformity, control.

Annealing through induction heating reduces steel stresses, increasing reliability.

The process involves heating and annealing the curve end of the heating element to reduce the internal stresses generated during the bending necessary to achieve the curved shape. This phase is crucial to ensure the stability and longevity of the heat elelment, enhancing their final quality.

Temperature control with thermal camera ensures accurate monitoring of the heat element curve, guaranteeing high-quality annealing.
Precise and uniform heating of the heat element reduces internal stresses and improves component reliability.

Information about annealing of heating elements through induction heating

The annealing of steel heating elements requires rigorous temperature control to reduce internal stresses, thereby improving the reliability and longevity of the component.

Thanks to the use of a custom inductor designed to ensure uniform heating across the entire surface of the heating element, and monitoring via a high-precision thermal camera, the annealing process is executed optimally with the following equipment and setting:

  • Generator: Utilizes a 25 kW Platinum generator at 80% capacity.
  • Temperature Achieved: 750°C in just 9 seconds.
  • Temperature Maintenance: Held for 4 seconds.
  • Custom Inductor: Ensures uniform heating across the entire surface.
  • High-Precision Thermal Camera: Monitors the process effectively.

This method ensures adherence to required annealing temperature limits, resulting in superior quality for the treated heating elements.
