電工鋼硅鋼片1882~1995年主要是熱軋硅鋼的發(fā)展階段。1903年美國和德國首先開始生產(chǎn)熱軋硅鋼。1905年美國（英國在1906年）已經(jīng)大規(guī)模生產(chǎn)，在很短的時間內(nèi)全部替代了普通低碳鋼板制造電機和變壓器。由于冷軋無取向硅鋼的磁感、山東德州當(dāng)?shù)罔F損、山東德州當(dāng)?shù)貨_剪加工性、山東德州當(dāng)?shù)乇砻尜|(zhì)量和絕緣涂層等質(zhì)量性能都大大優(yōu)于熱軋硅鋼，并且熱軋產(chǎn)品不能成卷生產(chǎn)，降低了沖片效率，60年代主要的工業(yè)發(fā)達 都陸續(xù)停止生產(chǎn)熱軋硅鋼。1957年，前西德阿什姆斯在實驗室內(nèi)生產(chǎn)出了雙取向硅鋼片（立方織構(gòu)的硅鋼）。沿軋向和橫向都有很高的磁性，但尚在實驗室階段，未投入工業(yè)生產(chǎn)。




電工鋼硅鋼片Electrical steel, also known as silicon steel sheet, is an indispensable metal material in the power, electronics, and military industries, and is also the largest functional material in production. It is mainly used as the iron core for various motors, generators, and transformers. Specific total loss (iron loss) is the total power consumed per unit mass of material when the magnetic polarization waveform remains sinusoidal, with a specific peak and frequency. The specific total loss is represented by the symbol P (Jm/f), in W/kg. Example: P1.5/50 represents the specific total loss at a maximum magnetic polarization intensity of 1.5T and a frequency of 50Hz. 3.2 Magnetic Polarization Q/BQB 480-20212 Magnetic polarization intensity refers to the peak magnetic polarization intensity of a specific magnetic field intensity when a sample is subjected to alternating magnetization. Its symbol is J (H), and the unit is T (Tesla). Example: J5000 represents the peak magnetic polarization intensity corresponding to a magnetic field intensity peak of 5000A/m. The material grades in this document are classified based on the nominal maximum specific total loss P1.5/50 (W/kg) at a magnetic polarization strength of 1.5T and a frequency of 50Hz, as well as the nominal thickness of the material. They are further divided into three categories based on product characteristics: ordinary type, stress relief annealing type, and high-efficiency type. Example 1: B35A210 represents a common non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 2.10W/kg； Example 2: B35AR300 represents a stress relieved annealed non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 3.00W/kg； Example 3: B35AH230 represents an efficient non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg. Example 4: 35WW210 represents a normal type WW non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.10W/kg. Example 5: 35WH230 represents an efficient WH non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg.
