Cold-rolled non-grain-oriented steel (CRNGO) is less expensive than cold-rolled grain-oriented steel (CRGO). CRNGO can be used in cost-oriented applications with the inconstant direction of magnetic flux, such as electric motors and generators. CRGO is usually in coil form and has to be cut into laminations further, being used in transformer core applications, such as certain internal parts in audio output transformers , Non-oriented electrical steel usually contains a level of 2%-3.5% silicon. It has similar magnetic properties in all directions, the so-called isotropy. Grain-oriented electrical steel usually contains a level of 3% silicon and is processed in a way to develop ideal properties in the rolling direction.
What is Silicon Steel ?
Silicon steel sheet is an alloy, and iron-silicon alloy formed by adding a small amount of silicon (generally below 4.5%) to pure iron is called silicon steel. This type of core has the highest saturation magnetic induction value of 20000Gs; because of their good magnetoelectric properties, it is easy to mass-produce, the price is cheap, and the mechanical stress has little effect, and it is widely used in the power electronics industry. Such as power transformers, distribution transformers, current transformers and other iron cores. It is the most productive and used material in soft magnetic materials. It is also the most used material in magnetic materials for power transformers. Especially suitable for low frequency and high power. Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel tape DW, cold-rolled oriented electrical steel tape DQ, suitable for all kinds of electronic systems, household appliances, medium and small power low frequency transformers and chokes, reactors , Inductor cores, these alloys have good toughness, can be punched, cut, and other processing, core lamination and winding type. However, the loss increases sharply at high frequencies, and the general frequency of use does not exceed 400 Hz.
From an application perspective, the choice of silicon steel must consider two factors: magnetics and cost. For small motors, reactors and relays, pure iron or low-silicon steel sheets are available; for large motors, high-silicon hot-rolled silicon steel sheets, single-oriented or non-oriented cold-rolled silicon steel sheets are available; single-oriented cold-rolled silicon steel is often used for transformers. sheet. When used at industrial frequency (50Hz), the thickness of the commonly used strip is 0.2~0.35mm; when used at 400Hz, it is appropriate to choose 0.1mm thickness. The thinner the thickness, the higher the price.

Application
Silicon steel is the most important magnetic material in industrial applications. The general applications include volt relays or pulse transformers from the generator, automotive, and transformer sectors.
Silicon steel is a soft magnetic material that is used in electrical power transformers, motors and generators. It has a high silicon content of about 3.2 mass %, which increases the electrical resistivity of iron and, therefore, reduces eddy current losses.
What is silicon steel used for?
Grain oriented silicon steel uses:
An important soft magnetic material in the military and electronic industries, it is mainly used in high-frequency transformers, high-power magnetic amplifiers, pulse generators, general yoke coils, inductors, storage and memory components, switches and control components, magnetic shielding and Transformers operating under vibration and radiation conditions. Compared with other materials such as ferrite and amorphous materials, the iron core can be made very small due to the high saturation magnetic induction and high magnetic permeability of the 3% Si-Fe thin strip. Because it is a cold-rolled strip, it has a smooth surface, small differences between the same plates, good plate shape, and good processing performance. It can be made into iron cores of various shapes and specifications such as CD type, ring type, and rectangular type. It has a wide range of applications. Wide frequency range (50H-20KH).
Applications of hot rolled silicon steel:
Hot-rolled electrical steel is mainly used for some small motors and micro-motors, such as some low-quality washing machines and range hood motors. There are also some high-specification and low-efficiency motors that can be hot-rolled 450.
Applications of cold rolled non-oriented silicon steel:
Basically non-oriented silicon steel is used in the motor. Gap motors (water pumps) mainly use cold-rolled, non-oriented, uncoated silicon steel. Electric welding machine motors are divided into two types: DC motors and AC motors. DC motors can use uncoated cold-rolled silicon steel, and AC motors mainly use coated ones. 600 non-oriented silicon steel.
