Oriented silicon steel, also known as grain-oriented electrical steel, is a type of magnetic material that is highly organized and has a preferred direction of magnetic alignment. This directional alignment is achieved during the manufacturing process by applying a strong magnetic field to the steel sheet as it is rolled. As a result, oriented silicon steel has low magnetic loss and high magnetic permeability, making it ideal for use in applications where efficiency is critical, such as in high-efficiency transformers.
How Does Oriented Silicon Steel Work?
Oriented silicon steel, composed of iron and silicon, plays a vital role in the cores of motors and transformers. These cores, responsible for guiding magnetic flux, benefit from oriented silicon steel's properties. Its high silicon content increases electrical resistance, effectively curbing energy-wasting eddy currents. Additionally, the aligned crystal structure allows swift magnetization and demagnetization. Consequently, oriented silicon steel excels in reducing energy losses and maintaining robust magnetic behavior, making it the ideal choice for optimizing the efficiency of electromagnetic devices.
Oriented Silicon Steel Classification
Silicon steel can be divided into low silicon and high silicon according to its silicon content. Low silicon contains less than 2.8% silicon. It has a certain mechanical strength and is mainly used to make motors, commonly known as motor silicon steel; high silicon contains 2.8%-4.8% silicon. It has good magnetism but is brittle and is mainly used to make transformer iron core, commonly known as transformer silicon steel.
According to the production and processing technology, it can be divided into two types: hot rolling and cold rolling. Cold rolling can be divided into two types: grain non-oriented and grain oriented. Cold rolling has uniform thickness, good surface quality and high magnetism. Therefore, with the development of industry, hot rolling has a tendency to be replaced by cold rolled sheets (our country has clearly required to stop using hot rolled silicon steel, which is what was previously called "cold rolling"). "Replace heat").
oriented Silicon steel Production Process
pickling
The descaler and hydrochloric acid tank are used to remove oxides from the hot-rolled steel strip to prevent surface defects of the cold-rolled finished product.
cold stamping
In order to ensure the thickness and material for different purposes, the reduction ratio is set at 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control are implemented.
annealing
It is a process that softens the steel strip material that has been hardened in the cold stamping process. Through metal heating and rapid cooling, we produce steel for deep processing and high-tensile strength steel, and adopt boxing (hood annealing) annealing and continuous annealing methods.
Insulating coating
When the silicon steel plate is processed into an iron core, in order to improve its processing performance and prevent eddy current loss equivalent to the thickness of the steel plate, continuous coating equipment is used to spray the insulating coating liquid on the upper and lower sides of the steel plate.

Feature Of Oriented Silicon Steel
Low iron loss is the most important quality indicator. All countries in the world are divided by iron loss value. The lower the iron loss, the higher the grade and the higher the quality.
01
The induction intensity is high, and silicon steel sheets with higher induction can be obtained under the same induction field. The iron cores of motors or voltage supports made with it are smaller in size and weight, and can relatively save silicon steel sheets, copper wires and insulation. Material.
02
High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the core.
03
Good stamping performance. This is more important for manufacturing small and micro motor cores.
04
The surface has good adhesion and weldability to the insulating film, which can prevent corrosion and improve punching performance. F. The magnetic aging phenomenon is small, and the silicon steel sheets must be annealed and pickled before leaving the factory.

Oriented silicon steel advantages
Low iron loss value
The core loss of silicon steel is very low, which means it can save a lot of electrical energy, extend the working time of motors and transformers, and simplify the cooling system.
High magnetic induction intensity
The high magnetic induction intensity of silicon steel reduces the size of the iron cores of motors and transformers, thereby saving silicon steel sheets, copper wires, and insulating materials.
Good punching performance
Silicon steel has good punching performance and is suitable for manufacturing micro and small motors.
Good surface quality
The surface of silicon steel is smooth, flat and uniform in thickness, which can improve the filling factor of the core.
Application of Oriented silicon steel
High magnetic permeability leads to low excitation currents and lower inductions.
Low hysteresis and eddy current losses.
Excellent lamination factor leads to better and compact designs and hence low material required.
High knee saturation characteristics.
Very low level of magnetostriction leads to noise reduction.
Enhances ease of winding and improves productivity.
