The core products are mainly used in transformers, reactors, and instrument transformers. Grain-oriented silicon steel is produced through a special process control that aligns the [100] axis of the body-centered cubic crystal lattice parallel to the rolling direction. Non-oriented silicon steel, on the other hand, has a basically random structure. Therefore, grain-oriented silicon steel is mainly used to manufacture transformers that require anisotropy and operate in a stationary state.
