The benefits of silicon chip
(2) performance index of silicon steel sheetA, low iron loss. The quality of the most important indicators, countries in the world to divide the value of iron, iron loss is lower, the higher the brand, the quality is high.B, high magnetic induction. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained, and the volume and the weight of the motor or transformer core made by it are relatively small. C, stacked high coefficient. The surface of silicon steel sheet is smooth, smooth and uniform in thickness.D, good punching. This is more important for the manufacture of small, micro motor cores.E, the surface of the insulation film adhesion and good welding.F, magnetic agingG, silicon steel sheet after annealing and pickling.
(1) classification of silicon steel sheetA and silicon steel sheet can be divided into two kinds: low silicon and high silicon. Low silicon silicon containing less than 2.8%, it has a certain mechanical strength, mainly used in the manufacture of motor, commonly known as dynamosheet; high silicon silicon content is 2.8%-4.8%, it has good magnetic properties, but more brittle, mainly used in the manufacture of transformer core, commonly known as the transformer silicon steel sheet. There is no strict limit in the actual use, the use of large silicon wafer manufacturing large motor. B, according to production and processing process can be divided into two kinds of hot rolling and cold rolling, cold rolling can be divided into grain orientation and grain orientation of the two. Cold rolled sheet of uniform thickness, good surface quality, high magnetic, therefore, with the development of industry, the trend of hot rolled sheet is cold rolled sheet has replaced (China has explicitly requested to stop the use of hot rolled silicon steel sheet, which is called "pre cold generation of heat")
The silicon steel sheet (sheet) Grade 600 to 1300Use: tableware / Accessories / motor can container / air conditioning accessories / small appliance parts / Accessories / microwave / lighting hardware accessories / furniture fittingsHardware knowledge: xigangpianElectrical silicon steel sheet or silicon steel sheet or steel sheet. As the name suggests, it is a silicon containing up to 0.8%-4.8% of electrical silicon steel, made of hot, cold rolled. General thickness below 1mm, so called sheet. The silicon steel sheet is a kind of plate, which is independent of its special use.The silicon steel sheet used in electrical engineering has excellent electromagnetic properties and is an important magnetic material in electric power, telecommunication and instrument industry.
(a) hot rolled silicon steel sheet for electrical purposes (GB5212-85)The hot rolled silicon steel sheet used for electrical engineering is made of soft magnetic alloy with low carbon content and low carbon steel, which is rolled into a sheet with thickness less than 1mm. Hot rolled silicon steel sheets for electrical purposes.Hot rolled silicon steel sheet according to the combination of silicon content can be divided into low silicon (Si = 2.8%) and high (Si = 4.8%) of silicon steel sheet two.(two) cold rolled silicon steel sheet for electrical purposes (GB2521-88)The silicon steel 0.8%-4.8% containing silicon steel is used as the material, which is formed by cold rolling.Two kinds of steel strip with grain orientation and grain orientation for cold rolled silicon steel sheet. The cold rolled electrical steel strip has the advantages of smooth surface, uniform thickness, high coefficient of lamination and good impact resistance, and has higher magnetic susceptibility and lower iron loss than the hot rolled steel strip. Instead of producing hot rolled motor or transformer with cold strip, its weight and volume can be reduced by 0%-25%. If the cold rolled oriented belt, better performance, use it instead of hot-rolled or cold-rolled low grade, can reduce the power consumption of the transformer 45%-50% transformer, and more reliable performance.For the manufacture of motors and transformers. In general, the grain oriented cold rolled strip is used as the state of the motor or welding transformer, and the grain oriented cold-rolled strip is used as the core of the power transformer, pulse transformer and magnetic amplifier.Plate size: thickness of 0.35, 0.50 and 0.65mm, the width is 800-1000mm, the length is less than or equal to 2.0m.
