Types of Induction Heating Coils

There are thousands of different induction coil designs with all sorts of different geometries, dimensions and materials used.  Many induction heating coils are created to achieve a simple task and are made in a  shop without any advanced studies and optimization.  Induction coils for "standard" applications (such as scanning coils for shafts and axles) have very significant resources for performance improvement.

The benefits of magnetic flux controllers are typically under-evaluated.  New magnetic materials and advancements in manufacturing technologies give additional opportunities for induction coil design improvement.  Computer simulation is also a very powerful tool for induction coil design and process optimization.

Advanced Induction Coil Design

Induction Heating Coils are essential components of the whole installation and their design and manufacturing quality are extremely important.

Before commencing an advanced induction coil design, a detailed analysis of specifications, available equipment and the environment as well are required. Sometimes, a "design for induction heating"strategy may be applied which includes:

• Modification of heat pattern specifications
• Part geometry modification
• Part Material Change
• Sequence of induction heating operations

Induction Heating coil style and heating process selection must be decided on beforehand, be in scanning, single shot, static, etc. A computer simulation should be run for optimization of the coil head as well as an analysis of the benefits of the magnetic flux controller application.  The coil should be engineered with the design of the coil head, leads, structural components, quenchant supply, etc. all in mind.  

Sometimes advanced manufacturing techniques should be tested in a laboratory or industrial plant to determine performance parameters and to decide if any final corrections may be required.

Induction Heating Coil Requirements

Induction Coils are the work tools of Induction Installations

Induction coils must meet specifications of temperature distribution and have good electrical efficiency. Also, they must have a satisfactory life time and provide a desired production rate.  In addition, an induction heating coil must have favorable parameters for efficient energy supply, such as a high impedance and power factor.

In order for a coil to be used in an induction installation, it must have low sensitivity to changes in the part dimensions and positioning in the specified range, all provided at a reasonable cost.  In many cases, magnetic flux controllers are required to achieve these goals.
