ABSTRACT:
The device has a lance. The lance is moved towards said molten bath level. An antenna is provided at a downward end of the lance for coaction with the slag interface (interfaces), when the lance is moved towards the slag interface (interfaces). A sensitive detection circuit is connected to said antenna. The antenna is during its downward movement capacitively coupled to said slag layer, and the detection circuit detects a predetermined impedance change (predetermined impedance changes) at the antenna provided as it is moved towards the interface (interfaces).
