Induction Heating Coils Design and Basic

HLQ Induction EQUIPMENT CO.,LTD Induction Heating Coils Design and Basic In a sense, coil Design for Induction Heating is built upon a large store of empirical data whose development springs from several simple inductor geometries such as the solenoid coil. Because of this, coil Design is generally based on experience. This series of articles reviews the fundamental electrical consider- ations in the Design of inductors and describes some of the most common Coils in use. Basic Design considerations The inductor is similar to a transformer primary, and the workpiece is equiva- lent to the transformer secondary (Fig. 1). Therefore, several of the charac- teristics of transformers are useful in the development of guidelines for coil Design .

Heating of internal bores, whether for hardening, tempering, or shrink fitting, is one of the major problems most com- monly confronted. For all practical pur- poses, a bore with a 0.44-inch (1.1-cm) internal diameter is the smallest that can be heated with a 450-kHz power sup- ply. At 10 kHz, the practical minimum ID is 1.0 inch (2.5-cm).
