Silicon lamination, also known as electrical steel sheet, is a soft magnetic alloy of ferrosilicon with very low carbon content. Silicon steel sheets are divided into hot-rolled and cold-rolled silicon steel sheets according to the manufacturing process, and now most international products are divided into two categories: non-oriented silicon steel sheets and grain-oriented silicon steel sheets according to grain orientation, with a general silicon content of 0.5-4.5%, which is mainly used in power frequency AC electromagnetic devices, such as transformers, motors, transformers, switches, and relays.
Cold-rolled oriented silicon steel sheet is mainly used in transformers, and cold-rolled non-oriented silicon steel sheet is mainly used in motors. Due to the complex process, narrow process window, and difficult production, the production of silicon steel sheet is known as the handicraft in steel products, especially the oriented silicon steel sheet. It is mainly used to make the cores of various transformers, motors, and generators. The world's silicon steel sheet production accounts for about 1% of the total steel production
