Adjusting method of slab crystallizer

The invention discloses a method for adjusting a slab crystallizer, which comprises the following steps of: in the process of circularly adjusting the width of the upper edge and the lower edge of the crystallizer, acquiring the target depth adjustment amount of a submersed nozzle, and adjusting the submersed nozzle by using the target depth adjustment amount. The adjusted actual depth of the submersed nozzle is matched with the adjusted width of the crystallizer; and after the width of the crystallizer is adjusted, the depth of the submersed nozzle is adjusted to the original depth. According to the adjusting method of the slab crystallizer, the fluctuation of the liquid level of the crystallizer can be accurately controlled, and therefore the surface defect occurrence rate of a casting blank in the casting process is reduced. 本发明公开了一种板坯结晶器的调整方法，在将结晶器的上沿和下沿循环调整宽度过程中，获取浸入式水口的目标深度调整量，并利用所述目标深度调整量对所述浸入式水口进行调整，使得调整后的所述浸入式水口的实际深度与所述结晶器调整后的宽度匹配；在所述结晶器的调整宽度完成之后，将所述浸入式水口的深度调整至原始深度。本发明公开的板坯结晶器的调整方法，能够精确控制结晶器液面波动，从而降低
