Method for evaluating flow field of crystallizer by means of vibration mark distribution of casting blank

The invention provides a method for evaluating a flow field of a crystallizer by means of vibration mark distribution of a casting blank. The method comprises the following steps that S1, vibration marks of the casting blank in a continuous casting production process are obtained in real time through an electrical high-temperature scanning device; S2, the vibration marks of the casting blank are analyzed, and distribution characteristics of the vibration marks of the casting blank are extracted; and S3, the overall liquid level of the flow field of the crystallizer is evaluated according to the distribution characteristics of the vibration marks of the casting blank, and the technological parameters in the continuous casting production process are adjusted according to the evaluation result. According to the method for evaluating the flow field of the crystallizer by means of vibration mark distribution of the casting blank, the distribution characteristic parameters of the vibration marks of the casting blan
