INDUCTIVE CROSS-FIELD HEATING - A FLEXIBL E HEATING PROCESS FOR METALLIC FLAT PRODUCTS

The paper first gives a brief overview of two inductive heating method s: axial flux and transverse flux heating, then goes on to present the results of numerical simulations of the heating process as well as me asurements taken and experience gained with a pilot plant. The results show that inductive transverse flux heating is a very flexible and ef ficient heating process for various applications in steel mills and ro lling mills. This applies particularly to thin-slab casting. In this c ase, optimum intermediate heating of the thin slabs can be achieved ev en with varying temperature distributions prior to entry into the heat ing bed. Transverse flux heating is also suitable for intermediate hea ting of thin-gauge strips. For this reason, it is expected to assume g reater significance once directly integrated into the rolling and fini shing processes.
