What is silicon steel or silicon steel?

The silicon steel sheet and silicon steel sheet are also called silicon steel sheets for electricians. It is a very low-carbon ferrosilicon soft magnetic alloy with a silicon content of 0.5 to 4.5%, which is hot and cold rolled. The general thickness is below 1mm, so it is called thin plate. It is mainly used to make iron cores for various transformers, motors and generators. The silicon steel sheet for electricians has excellent electromagnetic properties and is an indispensable important magnetic material in the electric power, telecommunications and instrumentation industries.

Classification of silicon steel sheet A, silicon steel sheet according to their different silicon content can be divided into two kinds of low silicon and high silicon. Low-silicon wafer containing 2.8% or less of silicon, it has a certain mechanical strength, mainly used for the manufacture of motor, commonly known as motor silicon steel sheet; high silicon silicon content of 2.8% -4.8%, it has good magnetic, but more brittle, mainly used In the manufacture of transformer core, commonly known as transformer silicon steel sheet. There is no strict boundary between the two in actual use, and high-silicon wafers are often used to make large motors.
B. According to the production and processing technology, it can be divided into two kinds: hot rolling and cold rolling. Cold rolling can be divided into two kinds of grains without orientation and grain orientation. The thickness of the cold-rolled sheet is uniform, the surface quality is good, and the magnetism is high. Therefore, with the development of industry, the hot-rolled sheet has a tendency to be replaced by a cold-rolled sheet (China has explicitly requested to stop using the hot-rolled silicon steel sheet, that is, the previous "On behalf of cold heat").
Performance index Silicon steel performance index A, low iron loss. The most important indicator of quality is that all countries in the world are classified by iron loss value. The lower the iron loss, the higher the grade and the higher the quality.
B, high magnetic induction. In the same magnetic field can obtain a higher magnetic induction of silicon steel sheet, using it to manufacture the motor or transformer core volume and weight, relatively speaking, can save silicon steel sheet, copper wire and insulation materials.
C, stacking factor is high. The surface of the silicon steel sheet is smooth, even and uniform in thickness, and the lamination factor of the manufacturing core is improved.
D, red filming is good. This is even more important for the manufacture of small, miniature motor cores.
E. The surface has good adhesion to the insulating film and weldability.

F, magnetic aging G, silicon steel sheet must be annealed and pickled after delivery.
