GNEE cold rolled non-oriented electrical steel for sale
Non-oriented electrical steel is a ferrosilicon soft magnetic alloy with very low carbon content. It is an indispensable and important material in the power, electronics and military industries.
With the development of high-speed and miniaturized motors, higher performance requirements have been put forward for non-oriented silicon steel, such as low iron loss and high magnetic induction at high frequencies. With the development of high-speed and miniaturized motors, higher performance requirements have been put forward for non-oriented silicon steel, such as low iron loss and high magnetic induction at high frequencies.
Among them, non-oriented silicon steel is the core material of motor and generator rotors that work in rotating magnetic fields, requiring good magnetic properties and process performance. Cold-rolled oriented silicon steel refers to cold-rolled electrical steel containing 2.9% to 3.5% Si, and the crystal structure of the steel plate has a certain pattern and direction.
Phosphorus: Phosphorus can improve the magnetic properties of iron-silicon alloys. Phosphorus can form iron phosphide at the grain boundaries, which can improve the punching properties of silicon steel. The segregation of phosphorus at the grain boundaries can hinder the nucleation and growth of recrystallized grains with unfavorable orientation and increase the magnetic induction intensity. At the same time, phosphorus will increase the resistance of silicon steel and reduce iron loss.
Manganese: Manganese can increase the resistance of silicon steel and reduce iron loss. But the role of manganese has a lot to do with sulfur content. When the hot rolling heating temperature is below the MnS solid solution temperature, the generated MnS can be coarsened; if it exceeds the MnS solid solution temperature, MnS will dissolve and disperse and precipitate during the subsequent cooling process, thereby reducing the magnetic properties.
Non-oriented Silicon Steel is known as CRNGO, it is Electrical steel made without special processing to control crystal orientation, non-oriented steel, usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic. Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO(Wiki definitation).

Feature of Non-oriented Silicon Steel:
- Low core loss and high magnetic flux density
- High dimension accuracy, high surface quality and high stacking coefficient
- Insulation film on surface, sound insulate on properties and process ability
Application of Non-oriented Silicon Steel:
CRGO is usually supplied by the producing mills in coil form and has to be cut into "laminations", which are then used to form a transformer core, which is an integral part of any transformer. Grain-oriented steel is used in large power and distribution transformers and in certain audio output transformers.
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.
