Induction Heating Principles

Transformer

The magnetic flux Φ made a circle in the core. Material flow (wire) with speed v and the annealing current I are parallel and rectangular to the magnetically flow Φ.

Cross field

The magnetically flow Φ is induced by the primary current in the windings of EE / CC-core and rectangular to material flow with speed v and annealing current I. The annealing current makes a circle in the material rectangular to the magnetically flow Φ.

Longitudinal field

The magnetically flow Φ is induced by the primary current in the windings of cylindrically coil and in direction of the axis of the coil. Material flow (wire) with speed v is rectangular to the annealing current I and parallel to magnetically flow Φ. The current made a circle in the material.

Characteristics of induction annealing (especially of the transformer principle )

  • High voltage and a lower current for the energy transfer
  • Contact less inductive energy transfer in the loop and conductive heating
  • Very High efficiency > 90 %
  • In praxis proofed mathematic-physical concept for dimensioning based on the material properties depend of temperature
Remarks particular to the annealing process
  • Simple line construction
  • Fewer wearing parts with a long life time
  • Very high surface quality
  • Suitable for a wide range of materials
    • copper and copper alloys
    • nickel and nickel alloys
    • special materials and composites
  • The lines can be configured for either round or flat wires.
