Analysis method and device based on hot continuous rolling strip steel tail thickness jump

The invention provides an analysis method and device based on hot continuous rolling strip steel tail thickness jump, and relates to the technical field of industrial hot continuous rolling. Comprising the steps of collecting strip steel tail thickness jump process data of each rack of a hot continuous rolling finishing mill; 1 second before steel throwing of an upstream rack is considered as the tail thickness jump stage of a downstream rack, the data sampling period is 10 ms, and the same-specification data of strip steel is classified; determining a DS-side roll gap thickness jump amount, an OS-side roll gap thickness jump amount, two-side roll gap thickness jump amount deviation, a rolling force deviation and a strip steel temperature attenuation value of the tail part of the strip steel; and the strip steel tail thickness jump amount is analyzed, and suggestions for impact of the next strip steel tail thickness jump on equipment and yield improvement are provided. On the basis of continuous judgment of c
