The Smooth flatthe surface insulating film silicon steel with good adhesion and weldability

    Silicon steel sheet is essentially an extremely low carbon steel plate with a mass fraction of 0.5%~5% silicon. According to the use, silicon steel sheet can be divided into motor silicon steel sheet (the mass fraction of silicon is usually less than 2.5%, and the thickness is generally 0.3ram) and transformer silicon steel sheet (the mass fraction of silicon is usually 2.9%~3.3%, and the thickness is generally O.35mm); According to the production method, it can be divided into hot-rolled silicon steel sheet and cold-rolled silicon steel sheet.

       Silicon steel with directionality is called grain-oriented silicon steel or oriented silicon steel. Oriented silicon steel is used in transformers, and the higher the degree of orientation, the better. This is because the higher the degree of orientation and the smaller the magnetostriction, the better the magnetism of the silicon steel sheet and the reduction of iron loss. Non-oriented silicon steel is used in the manufacture of electric motors.
