2.This helps maintain the material’s required chemical composition and mechanical properties, ensuring consistent transformer quality and reliability. In addition, the vacuum annealing process enables precise temperature control and uniform heating.
3.This allows the silicon steel sheet to be heated to the optimal annealing temperature and held at that temperature for the required time, thereby improving grain size and magnetic permeability. In addition, there is no air and moisture in the vacuum environment, which minimizes the risk of oxidation and contamination on the surface of the silicon steel sheet. This ensures a high-quality annealing process and reduces the need for additional cleaning or surface preparation steps after annealing.
4.In summary, the vacuum annealing furnace has significant advantages in the annealing process of transformer silicon steel sheets, including improved cleanliness, enhanced magnetic properties, controlled atmosphere, precise temperature control and reduced surface oxidation. These advantages contribute to the production of high quality and high performance transformers.
5.The vacuum environment provided by the annealing furnace eliminates oxygen and water, preventing oxidation and moisture on the material surface.
6.This ensures material purity, improves product quality, and reduces the need for subsequent cleaning and handling.
