Annealing and rapid demolding method for transformer wound core

The invention relates to the technical field of wound core annealing, in particular to a mutual inductor wound core annealing rapid demolding method which comprises the following steps: S1, winding a silicon steel sheet on a core mold, and placing a demolding layer between the core mold and the silicon steel sheet when the first circle of silicon steel sheet is wound; s2, winding the silicon steel sheet into an iron core, and annealing the iron core; and S3, after annealing is completed, the core mold is knocked, so that the core mold is rapidly separated from the iron core. When the first circle of silicon steel sheet is wound, the graphite paper is placed between the core mold and the silicon steel sheet to serve as a demolding layer, demolding can be completed under the knocking action after annealing, other complicated operation is not needed, the technological operation is simple and rapid, and the method has the advantages of being good in demolding effect, high in speed and the like. 本发明涉及卷铁心退火技术领域，具体涉
