The crystallizer vibrating device is used to accurately position the continuous casting machine crystallizer and drive the crystallizer to reciprocate regularly along the circumference of the casting radius determined by the process to prevent the billet shell from sticking to the crystallizer when drawing the billet, and to obtain good slab surface.
Vibration device has a variety of structural forms according to different use requirements
Vibration device can choose full leaf spring form, half leaf spring form, short arm four-link structure.
The matched driving device can choose mechanical drive, hydraulic drive, servo motor drive.

Horizontal full leaf spring vibration
Suitable for small billet continuous casting machine
Full leaf spring guide mechanism, high precision of guide motion trajectory, no gap, no lubrication, no maintenance, durable, easy installation
Drive form: mechanical drive, servo hydraulic, motor drive
Vibration frequency: 100-280c/min
Amplitude: level adjustable 0~±5
One of frame type full leaf spring hydraulic vibration
Features: compact structure, suitable for small billet continuous casting machine, small bearing capacity, not suitable for built-in electromagnetic stirring
Double-directional two-way preload spring steel plate guide group. High precision of guide motion track, no gap, no lubrication, no maintenance, durable, easy installation
Hydraulic servo control system: composed of hydraulic cylinder with displacement sensor and servo proportional directional valve. The process operation requirements of online adjustment of amplitude, vibration frequency and waveform are realized. At the same time, a pressure sensor can be installed to monitor the drawing resistance of the mold in real time, and provide data support for analysis of the mold breakout and other accident conditions.
Vibration frequency: 100~280c/min
Amplitude: online steplessly adjustable 0~±8
Bearingless maintenance-free hydraulic leaf spring vibration
Yunnan Taibiao, Shanxi Xintai, Shandong Yongfeng Steel Plant are in use.
