Elements of Induction Heating

Abstract

Elements of Induction Heating: Design, Control, and Applications discusses the principles of electromagnetic induction and the setup and use of induction heating processes and equipment. The first few chapters cover the theory of induction heating and the factors that must be considered when selecting and configuring components for a given application. As the text explains, the frequency required for efficient heating is determined by the geometry of the coil, the properties, size, and shape of the workpiece, and the need to maintain adequate skin effect. It also depends on proper tuning and load matching, which is explained as well. Subsequent chapters discuss the use of external cooling, temperature sensing, and power-timing devices, the fundamentals of process control, the role of flux concentrators, shields, and susceptors, and the integration of material handling equipment. The book also covers coil design and fabrication and explains how induction heating systems can be tailored for specific applications such as billet and bar heating, surface hardening, pipe welding, tin reflow, powder metal sintering, and brazing, and for curing adhesives and coatings.
