Induction Annealing Equipment and Processes

Induction Annealing

Radyne offers both non-ferrous and ferrous controlled processing equipment. Depending on the given material, this equipment is capable of full induction annealing, process annealing, or stress relieving. Induction annealing offers a number of attractive advantages over flame, including localized heating, easy control or elimination of a required controlled atmosphere, and rapid heating which permits minimum space allocation in a plant layout, particularly in continuous annealing operations.

Except in instances of bright annealing (no discoloration), induction annealing is often accomplished without a controlled atmosphere. This is possible since induction heating typically requires only seconds. Nevertheless, neutral or reduction atmospheres can be easily introduced when required by heating in a controlled atmosphere chamber.

Since induction heating is very rapid, heating may take place in a confined space. Induction coils for annealing are generally very short compared to furnaces or infrared tunnels. This advantage is particularly pertinent in continuous heating operations where induction heating may facilitate plant layouts and save considerable floor space.

Automatic processing can be readily accomplished by the use of suitable work handling fixtures such as indexing turntables, conveyors, or magazine feeds.

Localized Induction Annealing

Local heating facilitates further forming without the loss of strength from work hardening in the part as a whole. Particularly advantageous in parts which require maximum strength in service, strict control of the annealed zone is used to avoid loss of yield and tensile strength from previous work hardening in most of the part. This restores localized ductility in the area to be further formed.

Continuous Induction Annealing

Continuous annealing has proven very effective for processing tube, wire, strips, and extrusions. Able to be integrated in inline solutions, Radyne supplies complete systems for continuous annealing. When a controlled atmosphere is required, a quartz tube can be used to create a chamber permeable by induction.
