Method for eliminating folds at belt head of stainless steel vibration reduction composite plate

The invention discloses a method for eliminating folds at the strip head of a stainless steel vibration reduction composite plate, which is characterized in that a spray cooling device is arranged at the outlet of a substrate heating furnace of a composite plate production line, when the strip heads of a substrate and a compound plate penetrate through a composite roller for a certain distance, a PLC (Programmable Logic Controller) controls the spray cooling device to cool, so that the temperature difference between the substrate and the compound plate is reduced; the composite plate is not easy to expand and contract, so that the crease is eliminated, a traditional method for eliminating the crease by reducing tension on the composite plate is replaced, the waste material rate is greatly reduced, a subsequent wringing roller and a rubber roller cannot be scratched, the service life of a composite plate production line is prolonged, normal operation of the production line is ensured, and the production effici
