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、陕西西安当地铁损、陕西西安当地冲剪加工性、陕西西安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。
电工钢硅钢片厚度7.3.1.1 公称厚度产品的公称厚度为 0.35mm、陕西西安当地0.50mm、陕西西安当地0.65mm 三种厚度规格。7.3.1.2 厚度允许偏差厚度允许偏差包括以下三类，其中包括：— 同一个验收批内公称厚度的允许偏差，简称公称厚度允许偏差；— 平行于轧制方向（即钢带长度方向）的一定长度（2000mm±200mm）范围内，钢带纵向上各点的Q/BQB 480－20217实际厚度之间的偏差，以下称纵向厚度差；— 垂直于轧制方向（即沿着钢带宽度方向），钢带距离边部不小于15mm 及横向宽度中间位置，各点的实际厚度之间的偏差，以下称横向厚度差。产品的厚度允许偏差应符合表 5 的规定，带钢允许厚度负偏差交货。

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.
