Mill stiffness is an important parameter for strip rolling mill, but it is difficult to online detect. When the wide of strip are changed, or the rollers are changed, the mill stiffness will change slightly. This change can affect the thickness precision and flatness precision significantly. Making full use of the massive process data, the mill stiffness hidden in the data was found out by data mining. Firstly, according to the structure and principle of the rolling mill, the vertical thickness error equation and transverse thick error equation were established. According the error tracing theory, the stiffness tracing formulas were established. With the experiment data of 300 experimental four roll rolling mill, the stiffness analysis of rolling mill stiffness data were reliable. Experiment results showed that the plate thickness and shape control effect were good, using the rolling stiffness values from analysis.
