Abstract:
The invention relates to a method and a device ot detecting the presence of slag in a shroud (4) through which molten metal passes from a ladle (2) to a tundish (6). An induced voltage generated at a receiving coil (24) is compared with a defined voltage range. If the induced voltage has a value outside the defined voltage range it is indicative of the presence of slag. The voltage range is defined in dependence of the flow of molten metal passing through the shroud. The invention also relates to a casting plant.
