Abstract:
1. A method of determining a position of a solidification point in a strand ( 1 ) during a continuous casting of liquid metals and wherein the strand ( 1 ) formed in a continuous casting mold ( 4 ) and is displaced in support roller segments ( 5 ) provided with drive support roller pairs ( 6 ), the method comprising the steps of indirectly measuring a movable amount of a core liquid volume by direct measurement of generated process parameters on fixed or adjustable individual support rollers ( 6 a ) or groups ( 7 ) of fixed or adjustable support roller pairs ( 7 a ) with signal transmitters ( 10 ) which generate respective force and/or path signals which represent continuously changeable momentary positions of the solidification point in the cast strand ( 1 ) produced by continuous movement of the solidification to different locations along an entire solidification stretch during casting of the cast strand; producing a calculation model ( 15 ) for each momentary position of the solidification point ( 1 a ) based on the force and/or path signals; and continuously adjusting changeable casting parameters based on respective calculated positions of the solidification point.
