Method for aligning high-frequency data of continuous casting machine with continuous casting billet number

The invention relates to the field of continuous casting machine high-frequency data and continuous casting billet number alignment. According to the continuous casting machine high-frequency data and continuous casting billet number alignment method, the starting point is that a casting flow enters a crystallizer opening, the ending point is that the casting flow reaches a cutting position from a casting machine, high-frequency data collection is conducted at the time between the starting point and the ending point, and a time period with high-frequency data is formed; finding high-frequency data collected in the continuous casting billet time period of the continuous casting billet from the time period with the high-frequency data by taking the time from the head cutting starting time to the tail cutting starting time of each continuous casting billet as the continuous casting billet time period of the continuous casting billet; and aligning the high-frequency data acquired in the continuous casting billet
