Abstract:
The invention relates to an inductor to generate an electro-magnetic alternating field which is placed in a flow-out organ of a fusion tank and cross-flown with a cooling fluid for cooling. In order to operate the inductor using different coolants, the inductor (9) comprises at least two areas (12, 13) having separate inflow and outflow ducts (14, 15, 16, 17) for the cooling fluid, said areas being impinged upon by different cooling fluids.
Abstract:
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.
