Does the properties of cold-rolled silicon steel sheets affect heating?

Answer:

Are there two kinds of cold rolled silicon steel sheets with orientation and orientation?. The direction of the cold-rolled silicon steel sheet is obvious, that is, the magnetic property in the direction of rolling is good, the saturation flux density is high, and the unit loss and the unit excitation capacity are small. Now, cold rolled silicon steel sheet is used on the transformer. Hot rolled silicon steel sheets are free of orientation.
The use of silicon steel sheet processing cutting or stamping, on the properties of cold rolled silicon steel sheet effect is particularly evident, has little effect on hot rolled silicon steel, so the small capacity transformer adopts cold rolled silicon steel sheet, annealing can take measures after annealing can generally reduce the no-load loss is decreased by about 8%.
The unit loss of the cold-rolled silicon steel sheet is lower than that of the hot rolled silicon steel sheet at the same flux density and frequency.
The magnetic saturation point of cold rolled silicon steel sheet is high, and the flux density is saturated at 1.9T (19000Gs); the saturation point of hot rolled silicon steel sheet is about 1.6T (16000Gs).
