电工钢硅钢片根据生产方式可分为热轧电工钢和冷轧电工钢。热轧硅钢片因其性能落后近年已经逐步淘汰。根据晶体取向聚集程度将硅钢分为无取向和取向是为广泛接受的方法。冷轧无取向硅钢是指0.5％~4.0％(Si＋Al)的合金，冷轧至0.65mm、湖北黄冈同城0.5mm和0.35mm后经退火涂层后制成。相比取向硅钢，其晶粒织构类型较为漫散，各个方向上具有较为均匀的磁性能，而且磁各向异性较低，主要用作各类型电机和发电机的铁芯叠片。冷轧产品厚度精度，尺寸公差等级，表面光滑度都达到较高水平，从而提高了产品叠片系数和材料的磁性能。冷轧无取向硅钢生产工艺流程图如图1所示。

电工钢硅钢片：宝钢激光刻痕磁畴细化型产品磁性能检测采用了单片测试仪进行测试，通常情况下取向电工钢只测试平行于轧制方向的磁性能水平，特殊情况可以约定分别检测平行于轧制方向和垂直于轧制方向的磁性能。具体测试方法符合 GB/T 13789-2008（IEC 60404-3:2002，IDT）相关规定，测试试样公称尺寸为 500mm×500mm，测试试样长度的误差在±0.1％以内，测试试样的质量误差在±0.1％以内。为保证磁性测试结果对带钢磁性能的代表性，裁剪大单片试样时，试样中心位置与带钢宽度方向中心位置偏移量控制在≤50mm，试样边部距离样板边部控制在≥100mm，试样纵向与样板轧制方向的偏离角度≤1.0°，如附图 A.2 所示。试样要求剪切整齐、湖北黄冈当地平坦，直角性好，表面清洁，无影响性能试验的缺陷，试样边部不允许剪切后打磨，剪切毛刺高度不应高于 20μm。大单片试样不经过应力退火处理直接测试。

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.
