电工钢硅钢片硅钢是一种硅铁合金。用硅钢轧制的片材是电工领域中应用广的软磁材料，因而硅钢片又称电工钢片。硅钢片广泛用于电动机、发电机、变压器、扼流圈、电磁机构、继电器及测量仪表中电机工业大量使用厚度为0.35～0.50mm的硅钢片,用于：中型旋转机，压缩电机，通用马达，小型精密电机，电动汽车，压缩机，通用电机，电源变压器，精密变压器，节能电机，焊机变压器，稳压器，磁性密封器，加速器用电磁铁，汽车电机等；在电信高频技术中常用0.05~0.20mm的薄带钢片,以便更有效地降低涡流损耗。热轧硅钢片厚度为0.35～0.50mm，密度为7.55～7.70g/cm3,多用于大、中、小型交、直流电动机；冷轧无取向硅钢片厚度为0.35～0.50mm，密度为7.65～7.75g/cm3，多用于大型交流发电机、电动机，大、中、小型交、直流电动机；冷轧取向硅钢片厚度为0.23mm 0.27mm 0.3mm 0.35mm，密度为7.65g/cm3,多用于电力变压器、油浸式变压器，干式变压器，电抗器、磁放大器等；冷轧取向薄带厚度为0.05～0.20mm，多用于无线电高频变压器。

电工钢硅钢片1882~1995年主要是热轧硅钢的发展阶段。1903年美国和德国首先开始生产热轧硅钢。1905年美国（英国在1906年）已经大规模生产，在很短的时间内全部替代了普通低碳钢板制造电机和变压器。由于冷轧无取向硅钢的磁感、河北保定当地铁损、河北保定当地冲剪加工性、河北保定当地表面质量和绝缘涂层等质量性能都大大优于热轧硅钢，并且热轧产品不能成卷生产，降低了冲片效率，60年代主要的工业发达 都陆续停止生产热轧硅钢。1957年，前西德阿什姆斯在实验室内生产出了双取向硅钢片（立方织构的硅钢）。沿轧向和横向都有很高的磁性，但尚在实验室阶段，未投入工业生产。




电工钢硅钢片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.
