What is Electrical Steel ? (Silicon Steel)
Electrical steel is also referred to as silicon steel, transformer steel, or lamination steel.
Electrical steels are typically continuously cast or melted in oxygen furnaces before undergoing hot rolling through an annealing and descaling process to remove surface impurities. Subsequently, cold reduction adjusts the steel's thickness to meet end-user requirements.
Electrical steel sheets are widely used in modern society, such as AC electrical motors, compressors and transformers. The primary chemical composition of electrical steel is Silicon which is beneficial to electromagnetic properties.
Electrical steel made without special processing to control crystal orientation, non-oriented steel, has similar magnetic properties in all directions, i.e., it is isotropic. Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO.
Grain-oriented electrical steel is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control of the crystal orientation relative to the sheetIt is used for the cores of power and distribution transformers, cold-rolled grain-oriented steel is often abbreviated to CRGO.
CRNGO is less expensive than CRGO. It is used when cost is more important than efficiency and for applications where the direction of magnetic flux is not constant, as in electric motors and generators with moving parts. It can be used when there is insufficient space to orient components to take advantage of the directional properties of grain-oriented electrical steel.
