Non-oriented Electrical Steel

Non-oriented electrical steel

Non-oriented electrical steel is a very low carbon ferrosilicon soft magnetic alloy, is an indispensable important material in power, electronics and military industries. According to statistics, the total output of electrical steel in the world in 2000 was 6.714 million tons, and by 2005 it had exceeded 8 million tons. The domestic market has consumed well over 3 million tons. Among them, non-oriented silicon steel is the core material of motor and generator rotor working in rotating magnetic field, which requires good magnetic properties and process properties. With the development of motor high-speed and miniaturization, higher requirements have been put forward for the performance of non-oriented silicon steel, such as low iron loss and high magnetic induction strength at high frequency.

Cold-rolled oriented silicon steel refers to the cold-rolled electrical steel containing 2.9% ~ 3.5%Si, and the crystal structure of the steel plate has a certain rule and direction. Generally, it refers to the single oriented silicon steel sheet with Gaussian texture, that is, the (110) crystal face is parallel to the rolled surface, and the [001] crystal direction is parallel to the rolling direction. There is also a cold-rolled double-oriented (cubic texture {100}<001>) silicon steel. Function: Cold-rolled oriented silicon steel, also known as cold-rolled transformer steel, is used to manufacture the iron core of various transformers
