Continuous heating process is the process when the very long workpiece moves with determinate speed. 2DELTA can calculate the technological line with one workpiece. The process is non-stationary. 2DELTA provides to investigate the process from initial temperature of workpiece for example 20 °C to final. In this case parameters of inductors can change sufficiently.

Example 5 is the continuous variant of induction heating line for steel workpiece. Often some inductors have series connection and parallel circuit to compensate the reactive power. There are 8 circuits. The circuits 1, 2, 5, 6, 7 and 8 have two series connected induction coils. Both the circuits 3 and 4 have only 1 induction coil.

The temperatures along Z coordinate of the workpiece change from non-stationary to stationary distribution.

2DELTA provides to investigate the process used simultaneously multi frequency power sources. Often frequency in non-ferromagnetic stage must be more than in ferromagnetic. You may increase the electrical efficiency if induction coils 10, 11, 12 and 13 will have frequency 10 kHz instead 4 kHz.
