A process for heating a fireproof moulding (1) by means of an induction device (2), in which at least one subsidiary electromagnetic field (B) is generated besides the main electromagnetic field (A) generated by the induction device (2), and a corresponding moulding for such a process. The moulding, for example a ceramic dip casting tube (16), has, for this purpose, an electrically conductive layer (6) with insulating interruption slots (7, 10, 11) for the controlled deflection of the induced eddy currents.
