Product Description

Product Description

Electrical steel usually referred to as cold-rolled electrical steel, can be divided into two major categories including grain-oriented electrical steel and non-oriented electrical steel. Grain-oriented electrical steel, with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in this direction including low core loss, high permeability, and low magnetostriction, and is widely used in the transformer industry. Further, it can obtain lower core loss by domain refinement treatment. Meanwhile, non-oriented electrical steel, featured by a random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.
We believe we will be helpful for the customer to take advantage of the characteristics of our products so as to design and manufacture more excellent electric and electrical products.

Product classification

Silicon steel is a silicon iron alloy with a silicon content of 3%~ 5%.Divided into oriented silicon steel and non-oriented silicon steel, it is an important soft magnetic alloy which is indispensable for power, electron and military industry.Was once known as "the arts and crafts of steel products"

We have Silicon Steel Coil in Non Oriented and and oriented type, commonly used in barretter,rotor of motor. Material are 23Q110 30Q120 35Q145 35WW230 35WW250 35WW270.astm 36F145 36F158 36F168 36F180 M80050A

Silicon steel classification 
Hot rolled silicon steel sheet
Hot rolled silicon steel sheet is Fe - Si alloy with open hearth and electric furnace melting, repeated hot rolled into sheet, finally, in 800-850 ºC after annealing.Hot rolled silicon steel sheet is mainly used for the manufacture of generator, so it is also called hot rolled motor silicon steel sheet, but its utilization is low and the energy loss is large. In recent years, relevant departments have forced the elimination of the demand.
Cold-rolled non-oriented silicon steel sheet
The main purpose of cold-rolled non-oriented silicon steel is used for generator manufacturing, so it is also called cold rolled motor silicon steel.It has a silicon content of 0.5% to 3.0%, and the supply state is 0.35mm and 0.5mm thick steel strip after cold rolling to finished product thickness.The Bs of cold-rolled non-oriented silicon steel is higher than the oriented silicon steel.Compared with hot rolled silicon steel, its thickness is uniform, its dimension is high and its surface is smooth and smooth, thus the filling coefficient and magnetic energy of the material are improved.
Cold-rolled oriented silicon steel sheet
The most important purpose of cold-rolled oriented silicon steel belt is for transformer manufacturing, so it is also called cold rolled transformer silicon steel.Compared with the cold-rolled non-oriented silicon steel, the magnetic orientation of the oriented silicon steel is strong.It has superior permeability and low loss characteristics in the direction of easy magnetization.The iron loss of the orientation steel strip in the direction of rolling is only one third of the horizontal one, and the ratio of the magnetic conductivity is 6:1, and the iron loss is about 1/2 of the hot-rolled belt, and the magnetic conductivity is 2.5 times that of the latter.

FAQ

Q&A

Q:What is silicon steel? What is electric steel?

A:Electric steel is magnetically soft material among functional material, and is most wildly used. Generally speaking, silicon steel refers to electric steel with silicon content between 0.5%~6.5% Si. The general electric steel also includes the part that contains little silicon (Si<0.5%). However, nowadays the 2 concepts are not clearly defined, and can be interchangeable.

Q:Classification of electric steel

A:It is roughly classified into hot-rolled electric steel and cold-rolled electric steel.Zhongyuantong steel produces cold-rolled electric steel, which can be further classified into oriented electric steel and non- oriented electric steel.

Q:What is magnetic field?

A:The space field for the acting force between the two magnetic poles is described as magnetic field strength H, the unit is A/m (Ampere/meter). It is the driving primary field produced by external input electric current after the electric steel is made into motor.

Q:Difference between electric steel B50A300 and B50AR300

A:B50A300 is whole processed product. It can be put into use after being purchased or annealing (reducing the loss through stress relief and construction perfection). But B50AR300 must go through annealing before use.

Q:Difference between whole processed silicon steel and semi- processed silicon steel

A:The target of whole processed non-oriented silicon steel annealing is to achieve targeted magnetic property (guarantee value), with the consideration of mechanical property required by stamping and the surface coating. The target of semi-processed product annealing is to achieve the mechanical property required by stamping. The manufactured magnetic property is so poor that the user has to do annealing and bluing to the magnet core so as to achieve the required magnetic property and surface insulation. There can be coating on the semi-processed non-oriented electric steel (applied in Japan market) or no coating (applied in American market, CRML).

Q:Influence of electric steel hardness on product process property

A:The mechanical property of the material has direct influence on the processing property. Various electric steel materials are used in various industries according to their characters. Processing mold and mold adjustment are critical to processing property.Zhongyuantong steel maintains the stability of product mechanical property and guarantees the user's processing property.

Q:How doesZhongyuantong inspect the hardness of silicon steel material?

A:According to the silicon steel character (thickness, material),Zhongyuantong steel inspects with HV1 standard. There is no conversion relation between Vickers Hardness, Brinell Hardness, Rockwell Hardness, and other Hardness, but there is empirical reference.
