Abstract (en)

[origin: US4635832A] In a method of casting a metal melt from a metallurgical vessel, in which the metal melt is covered by a slag layer, into another metallurgical vessel, the metal melt is guided through a casting tube, which covers the casting jet between the vessels. In order to reliably ascertain the passage of slag through the casting tube with very little expenditure, magnetic fields are induced in the casting jet by two coils peripherally surrounding the casting tube. The difference of the inductivity variations caused in the two coils by the eddy currents produced by the magnetic fields in the casting jet is continuously measured and compared to a least one limit value and casting is interrupted in case the limit has been exceeded or fallen short of.
