Abstract: At present, because of no technological parameter of the cold rolled silicon steel rewinding process mapping with the strip length, the existing technology is unable to view the processing parameters of the unit length of strip steel, unable to get the strip length position in the previous process corresponding to the length value of the unit length, and unable to provide a prerequisite for the length traceability in subsequent cross process. A coil tracking method for cold rolled silicon steel rewinding was introduced in this paper. The L1 first-level process parameter information and L2 second-level production information are processed, and then according to the length relationship between the uncoiler and the coiler, the length mapping of the coil can be formed after processing, that is, the length of the sub-coil after the rewinding process can be traced back to the length of the coil in the previous process. The length information is mapped to L1 process parameter to form digital coil, which can realize the coil tracking of the cold rolled silicon steel rewinding.
