Beschreibung
Zusammenfassung:	The present invention refers to a method for determination and control of the amount of nitrogen dissolved in metallic liquid phases and to a device permitting, when placed in the steel producing plant and for instance in the tundish or in the continuous casting mould, the determination of nitrogen content directly from the liquid phase. Such a device can point out possible nitrogen pick-up in real time, thus permitting to immediately intervene.
