Notes:
The inductive heating of the feedstock material is a very important step in the processingof semi solid metals. On the one hand, the billet has to be heated as fast as possible to the targettemperature. On the other hand, it must be guaranteed that the outer area does not begin to meltprematurely. Also, at the end of the heating the billet should have an uniform temperaturedistribution in order to obtain good forming results. A flatness based control will be presented tocalculate the induced power over time trajectory from a desired trajectory for the temperature in themiddle of the billet. The temperature trajectory has to be chosen so that the billet has the desiredtemperature behaviour. Experimental results will be shown for the flatness based inductive heatingof X210CrW12 just below the semi solid state
