Method and device for determining the position of the crater end in the cast strand during continuous casting of liquid metals, particularly liquid steel materials

A method and means for determining the position of the crater tip (1a) in the cast strand (1) in the continuous casting of liquid metals, particularly of steel materials, lead to more accurate results by an indirect measuring of the core liquid volume per unit length, or over the full strand length by an indirect measurement of self-adjusting process parameters using force and / or displacement signals (10) at a fixed or engagable support roller pairs (7a) is carried out, and that, based on these measurement values, a model calculation (15) for the instantaneous position of the crater tip (1a) is created be adapted continuously variable basis of which the casting parameters.
