GNEE New Material Grain Oriented Silicon Steel Core
Grain-oriented electrical steel usually has a silicon level of 3% (Si:11Fe). It is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control (proposed by Norman P. Goss) of the crystal orientation relative to the sheet. The magnetic flux density is increased by 30% in the coil rolling direction, although its magnetic saturation is decreased by 5%. It is used for the cores of power and distribution transformers, cold-rolled grain-oriented steel is often abbreviated to CRGO.

Cold Rolled Silicon Steel E Cores
Core performance requirements
Electrical components such as motors and transformers are generally required to have high efficiency, low power consumption, small size, and light weight. Electrical steel plates usually use core loss and magnetic induction as the guaranteed magnetic value of the product. The performance requirements of electrical steel plates are as follows:
Low core loss (PT)
Iron core loss refers to the ineffective electric energy consumed when the iron core is magnetized under an alternating magnetic field of ≥50Hz, referred to as iron loss, also known as alternating loss, and its unit is W/kg. This kind of ineffective electric energy consumed by various obstacles due to changes in magnetic flux not only loses electric energy through the heating of the iron core, but also causes a temperature rise in the motor and transformer. The iron loss (PT) of electrical steel includes three parts: hysteresis loss, eddy current loss (Pe) and abnormal loss (Pa). The electrical steel plate has low iron loss, which not only saves a lot of electrical energy, but also extends the running time of the motor and transformer and simplifies the cooling device. Since the power loss caused by the iron loss of electrical steel plates accounts for 2.5% to 4.5% of each country's annual power generation, the production of electrical steel plates in various countries always tries every means to reduce iron losses. And the iron loss is used as the most important indicator to evaluate the magnetic properties of the product, and the iron loss value of the product is used as the basis for classifying the product grade.
