Description

Technical Field

[0002] The crystallizer vibration mechanism is an important part of the continuous casting machine, which is mainly used to drive the crystallizer to vibrate up and down. This vibration mechanism makes the crystallizer move along the radius of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics, thereby optimizing the demoulding process of the cast billet.

[0003] Vibration can reduce the bonding force between the ingot and the mold wall, making demoulding easier and improving production efficiency. The vibration of the mold can also help reduce the friction resistance of the billet and prevent the ingot from bonding to the copper wall of the mold during solidification.
