Induction Annealing Equipment

Induction annealing is a part of induction heating. The purpose of induction annealing is to change the hardness, toughness and internal stress of the metal in order to achieve the best material properties.

The advantage of induction annealing is that the workpiece can be heated precisely and repeatedly, thus ensuring the same result. In the process of induction annealing, the heat quantity is generated directly in the workpiece by alternating electromagnetic field, so the process can be controlled precisely, and the high efficiency can be achieved by the effective use of energy.

Thus, uniform heat distribution and workpiece penetration depth can be ensured. In induction annealing, the annealed workpiece won’t be cooled suddenly by water or other coolants, but indirect cooling slowly, there is not directly contacting during the heating process.

Induction annealing provides excellent heating controllability because the whole process can be controlled perfectly with frequency, power, and annealing time according to the required material characteristics.





It is suitable for welding seam annealing(removing internal stress) of welded tube, (on line) bright annealing of wires, tubes, sheets , annealing of stainless steel wares after stretching, and annealing of various hardware tools.
