Resumen
- The heating of flat workpieces of different materials and geometrical characteristics (width, thickness) is often required in the metal industry. The temperature requirements depend on the process to which the workpiece should undergo and the mechanical and chemical characteristics which must be obtained by the heat treatment. For certain applications in which the electrical resistivity of the workpiece material is low or the ratio between the width and thickness of the body is high, the classical longitudinal flux induction heating is efficient only if high frequencies are used. A good alternative is the travelling wave induction heating (TWIH) which has a structure similar to the linear induction machines (LIM).
