Zusammenfassung:	The invention provides a control method for macular corrosion of a cold rolling pickling machine set. The control method comprises the following steps: first, determining possible reasons for formation of the macular corrosion, and then controlling the formation of the macular corrosion according to the possible reasons for the formation of the macular corrosion, wherein the possible reasons for the formation of the macular corrosion comprises the following seven types: the macular corrosion formed in a low-speed process of a process stage, the macular corrosion formed by over-high concentration of residual C1 on the surface of band steel, the macular corrosion formed by excessive temperature difference between a water temperature and an acid temperature in a bleaching stage, the macular corrosion formed by accidental shutdown or slow speed, the macular corrosion formed by low pressure of a squeezing roller and low temperature of a drying machine in the process stage, the macular corrosion formed by instabili
