Abstract
In a device for identifying the solid-liquid-interface of a melt while withdrawing the poured full ceramic mold 6 from the heater 7, 8 which at least partially encloses the casting mold 6, the mold 6 is at least partially enclosed by two receiving loops 4, 5 disposed in the inside of the heater 7, 8 and a polarizing transmitting loop 13; the induction or receiving loops 4, 5 are coupled with an electric evaluation circuit 9, 10, 11 and polarizing transmitting loop 13 which is connected to a transmitter 14 sends a signal into the casting mold 6 the level of which is sensed by the receiving loops 4, 5 and the so obtained signals create a value for the solidification of the melt in the casting mold 6 by determining the difference of inductivity between ordered, crystalline and disordered, liquid metal mass.
