STRAND CASTING HAVING OPTIMIZED OSCILLATION OF THE STRAND CASTING MOLD

Liquid metal (2) is poured into a strand casting mold (1) of the strand casting system. The liquid metal (2) solidifies on side walls (3) of the strand casting mold (1) into a strand shell (4). The strand shell (4) is drawn out of the strand casting mold (1) in a casting direction (x) at a casting v...

Zusammenfassung:	Liquid metal (2) is poured into a strand casting mold (1) of the strand casting system. The liquid metal (2) solidifies on side walls (3) of the strand casting mold (1) into a strand shell (4). The strand shell (4) is drawn out of the strand casting mold (1) in a casting direction (x) at a casting velocity (vG) by means of a draw-off device (6) of the strand casting system, with or without a core (5) that is still liquid. The strand casting mold (1) is periodically moved in the casting direction (x) by means of an oscillating device (8) of the strand casting system. The oscillating device (8) is controlled by a control device (9) of the strand casting system. In a first time segment (T1) of the period, the motion of the strand casting mold (1) is a harmonic oscillation, on which a velocity offset (v1) is superposed. In a second time segment (T2) of the period, the motion occurs with constant velocity (v3).
