In 1900, British Hadfield (R.A. Hadfield) and others first discovered that Si-Fe alloy containing Si4% has good magnetic properties. In 1903, Germany and the United States successively produced hot rolled silicon steel sheets containing 1.0% to 4.5% Si. In 1906, it replaced low carbon steel and was used to manufacture motor and transformer cores. In 1934, the US Goss (N.P. Goss) used two cold rolling methods to make (110) [001] grain oriented cold-rolled silicon steel sheets containing Si3%. In 1968, Japan ’s Taguchi et al. Used a comprehensive inhibitor of manganese sulfide and aluminum nitride and used a large reduction cold rolling method to produce (110) [001] highly magnetically oriented silicon steel. The grain orientation of this material is more accurate , Iron loss and magnetic properties are further improved.
