The invention relates to the technical field of horizontal continuous casting, in particular to a horizontal continuous casting copper pipe blank process parameter abnormity monitoring method, which comprises the following steps of: collecting a plurality of section samples in a horizontal continuous casting copper pipe blank production process and process variable data corresponding to each section sample; preprocessing the process variable data to obtain a data matrix; performing standardization processing on the data matrix to eliminate the magnitude influence relationship of each piece of process variable data to obtain a standardized matrix; performing feasibility test on the standardized matrix, and if the test is not passed, increasing the number of samples or the type of process variable data; performing factor analysis on the standardized data by using a principal component analysis method, determining the number of common factors, establishing a factor load matrix and performing factor rotation; rea
