Description

Technical Field

[0001] The present invention relates to the technical field of crystallizer control, and in particular to a crystallizer vibration control system, method, electronic equipment and storage medium. Background Art

[0002] The crystallizer is one of the important equipment in continuous casting production. The vibration of the crystallizer is equivalent to a demoulding effect, the purpose of which is to prevent the billet from being cracked or leaking due to bonding. At the same time, when the crystallizer vibrates up and down, it can periodically change the relative position of the steel liquid level and the crystallizer wall, which is beneficial to improve the lubrication condition of the clean surface, reduce bonding resistance and friction, and improve the surface quality of the billet.
