Abstract：Asymmetric flatness errors have a great influence on strip wandering in continuous annealing lines，especially the edge buckle. In order to present the asymmetry of flatness，asymmetry ratio is introduced. The relationship between strip wandering distance and asymmetry ratio is analyzed，which shows when the average asymmetry ratio of a length of strip rises above 0.5，the wandering distance of strips also increases. On the basic of analysis a standard of strip flatness produced by cold rolling progress is determined，with which the number of strip break in annealing line caused by flatness errors falls from 8 times per year to 3 times per year.
