The invention relates to the technical field of plate-shap control in the band steel rolling of a successive mill and discloses a band edge thickening integrative control method which is applicable to a common four rollers hot band steel successive milling machine without milling roller transverse movement, online milling mill roller and band steel edge lubrication. Through optimizing the original roller type curve of the operating machine set of a finishing mill, the transverse distribution of the cooling water of the operating roller and reasonably controlling the milling rhythm, the invention realizes the control of the thickening operation in the region of about 40 to 60mm from edge of the hot milling band steel. The invention solves the problem that the present common four rollers successive mill has no effective control method for the phenomenon of the edge thickening except for additionally adding specialized devices. The invention provides the common rollers and PC mills which have no auxiliary devices such as milling roller transverse movement, online milling mill roller, band steel edge lubrication and so on with a band steel edge thickening integrative control method and need not add devices.
