Silicon steel coil Baosteel oriented silicon steel sheet
, Cold-rolled oriented silicon steel sheet
,
, The main use of cold-rolled oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel . Compared with cold-rolled non-oriented silicon steel, the magnetism of oriented silicon steel has strong directionality and has superior high magnetic permeability and low loss characteristics in the rolling direction that is easy to magnetize. The iron loss of oriented steel strip in the rolling direction is only transverse/
, and the ratio of magnetic permeability is
times of the latter.
, High magnetic induction cold-rolled oriented silicon steel strips
,
, High magnetic induction cold-rolled silicon steel strips are single-oriented steel strips, mainly used in various transformers and transformers in the telecommunications and instrumentation industries. Manufacturing of electromagnetic components such as choke coils. Its application scenarios have two main characteristics. One is that under small current conditions, that is, weak magnetic fields, the material is required to have high magnetic properties in the weak magnetic field range, that is, high &
values and high
values. The second characteristic is that the frequency of use is high, usually above
or even as high as
. In order to reduce eddy current losses and effective magnetic permeability under alternating magnetic fields, thin strips are generally used.
, Performance
,
, The main performance requirements for silicon steel are
,
and low iron loss, which are the most important indicators of the quality of silicon steel sheets. Countries all classify grades according to the iron loss value. The lower the iron loss, the higher the grade.
,
The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the volume and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires and insulating materials.
,
, the surface is smooth, flat and uniform in thickness, which can improve the filling factor of the core.
,
It has good punching properties, which is more important for manufacturing micro and small motors.
,
The surface insulating film has good adhesion and weldability, can prevent corrosion and improve film punching properties.
, the company is Baosteel's first-level agent/

Wugang's non-oriented silicon steel can be divided into full-process non-oriented silicon steel and semi-process non-oriented silicon steel according to different production process conditions. In addition, according to the professional application field To improve the performance, special non-oriented silicon steel has also been developed.
,
Silicon steel sheet is a ferrosilicon soft magnetic alloy with extremely low carbon content,
generally the silicon content is
~
%. Adding silicon can increase the resistivity and maximum magnetic permeability of iron, and reduce coercive force, core loss (iron loss) and magnetic aging. Mainly used to make iron cores for various transformers, motors and generators.
