Electrical steel usually refers to cold-rolled electrical steel, divided into grain non-oriented electrical steel and oriented electrical steel. Non-oriented electrical steel crystals.The particle direction is randomly distributed, and the electromagnetic properties are uniform. Oriented electrical steel is easily magnetized, and the grain direction is divided along the rolling direction Cloth, rolling direction has the excellent characteristics of high magnetic induction, low iron loss and low expansion, and can also be refined by magnetic domain.Technical treatment to obtain lower iron loss. Electrical steel is an indispensable part of a country's economic construction and people's life.Raw material products, its products are widely used in various industries, such as large generator sets, household appliances, small and medium-sized electricity machine, transformer and other emerging fields.
