Oriented Silicon Steel
Oriented Silicon Steel
Silicon steel, also known as electrical steel, is ferritic alloys of iron and silicon that have magnetic properties which make them useful in motors and transformers. The silicon additions improve magnetic softness and increase the electrical resistivity. Such as creating a hysteresis area, increasing magnetic permeability, and reducing core loss. It is an important component in the field of electrical engineering. A widely used soft magnetic alloy. Silicon steel can be divided into two categories: oriented silicon steel and non-oriented silicon steel.
The magnetism of grain-oriented silicon steel has strong directionality, with the lowest iron loss value in the rolling direction, the highest magnetic permeability and high magnetic induction value under a certain magnetizing field. The silicon content of grain-oriented silicon steel is about 3%, and the steel is required to have low oxide inclusion content and must contain certain inhibitors (MnS, A1N). Because it is mostly used in the manufacture of transformer cores, it is also called cold-rolled transformer steel.
