ABSTRACT
This chapter is devoted to a discussion of the use of induction heating principles for a large group of applications referred to as mass heating. This term applies to a variety of applications where metal is heated for forging, forming, extrusion, coating and the like. Typically it is required to heat the workpiece uniformly within its body. However, it is sometimes necessary to heat certain areas of the workpiece selectively and care must be taken to provide uniformity in the temperature distribution. Certain applications such as extrusion may require a nonuniform end-to-end temperature profile. All of the most typical applications of mass heating are discussed in this chapter.
