Description

technical field [0001] The invention relates to a silicon steel sheet. It belongs to the field of electromechanical technology. Background technique [0002] Silicon steel sheets for electrical purposes are commonly known as silicon steel sheets or silicon steel sheets. It is a silicon-iron soft magnetic alloy with extremely low carbon content, generally with a silicon content of 0.5-4.5%, and is made by hot and cold rolling. Generally, the thickness is less than 1mm, so it is called thin plate. Adding silicon can increase the resistivity and maximum permeability of iron, and reduce the coercive force, core loss (iron loss) and magnetic aging. It is mainly used to make iron cores of various transformers, motors and generators. [0003] The existing silicon steel sheet has low energy conversion rate and low material utilization rate. [0004] The existing silicon steel sheets cannot effectively prevent electromagnetic waves and cannot meet the needs of customers. Conte...
