Generally speaking, transformer silicon steel sheets are referred to as plate silicon steel sheets or silicon steel sheets. As the name suggests, it contains 0.8% silicon and -4.8% silicon steel, cold-rolled and hot-rolled. A typical thickness of 1mm describes the following thin plate. Plate silicon steel is a type of metal with special intentions and separated branches.

Excellent electromagnetic properties, energy, communication, measuring instruments, industrial and sheet silicon electric steel are essential magnetic materials.

(1) Classification of Silicon Steel Plates

According to their different silicon contents, silicon steel plates can be divided into two types: low silicon and high silicon. Silicon with a low silicon content of less than 2.8% has mechanical strength and is primarily used for engine manufacturing, which is generally referred to as the silicon steel engine title. 2.8% high silicon content silicon -4.8%, but it uses magnetic ferrite but is more fragile, primarily used for transformer cores, generally referred to as thin sheet silicon steel. When applying two non strict constraints in practice, high-grade silicon is generally used to make large motors. B， According to production and processing technology, it can be divided into two types: hot rolling and cold rolling. Cold rolling can be divided into two types: particle orientation and particle direction. Cold rolled plates have uniform thickness, good surface quality, and high magnetism. Therefore, with the development of industry, hot-rolled plates have been replaced by trend cold-rolled plates (China explicitly requires steel hot-rolled silicon to stop using it).

(2) Functional indicator steel plate

Low iron loss. The more important quality indicator is that the higher the international quality, the higher the iron loss, the higher the iron grading, and the higher the quality.

B， High magnetic induction. By following the production of its engine, you can obtain the high magnetic direction or conversion core component and minimum component of silicon steel, and in the same magnetic field, it can save relative thermal insulation of silicon steel, copper, etc. C， High stacking coefficient. Silver plated steel with a smooth and even surface thickness increases the lamination factor of the production center.

D， The red film is good. It is more important than making small magnetic cores for small motors.

E， The adhesion and good weldability of the insulation film surface.

F， Magnetic aging

G， Annealing silicon steel plate and soaking it after delivery.

(A) (GB 5212-85) Hot rolled silicon suitable for electrical steel plates

Low carbon iron silicon loss hot-rolled silicon steel for hot magnetic alloy plate data board is rolled to thin plates with a thickness of less than 1mm. There is also hot-rolled silicon steel plate and hot-rolled silicon steel plate, known as sheet metal.

According to the amount of silicon, hot-rolled silicon steel can be divided into two types of steel with low silicon content (≤ 2.8% Si) and silicon (≤ 4.8% Si).

(2) Cold rolled silicon steel for electrical engineering steel plates (GB 2521-88)

By cold rolling, 0.8% -4.8% of silicon is used as the material for production.

Grain and grain orientation of non oriented cold-rolled silicon steel. Smooth surface rolled electrical steel, cold-rolled steel strip with uniform thickness compared to hot-rolled electrical steel, high stacking coefficient, stamping and other functions, and low magnetic induction iron loss. On the contrary, the use of electric motors or tropical transformers with cold belts can reduce their weight and volume to 0% to 25%. Instead of using cold-rolled strips, hot-rolled strips or cold-rolled strips with poor raw material quantity can be used for better functionality. If the processor power consumption can be reduced by 45% -50%, a transformer with reliable functionality can be used.

It is used to make motors and transformers. Generally, strips are used as conditions for crystal oriented cold motors or welding transformers, cold-rolled strip oriented particles are used as centers for power transformers, transformer roller pulses, and magnetic amplifiers.

Steel plate dimensions: thickness 0.35mm, 0.50mm, 0.65mm, width 800-1000mm, length ≤ 2.0m.
