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. The classification and code of insulation coatings shall comply with the provisions of Table 2. Table 2 Classification and Code of Insulation Coatings Type Code Characteristics of Insulation Coatings Semi organic Thin Coating A Improves Punching Performance and Has Good Weldability Semi organic Thick Coating H has Good Punching Performance and High Interlayer Resistance Semi organic Chromium Free Thin Coating K does not contain chromium and has good weldability Semi organic Chromium Free Thick Coating M does not contain chromium and has good insulation performance Semi organic Chromium Free Extreme Thick Coating J does not contain chromium and has excellent insulation performance Semi organic Chromium Free Ultra Thick Coating L does not contain chromium and has extremely high insulation performance Self adhesive Coating
电工钢硅钢片：比总损耗(铁损)specific total loss (iron loss)比总损耗是指在磁极化波形保持正弦，其峰值和频率为特定值时，单位质量材料所消耗的总功率，比总损耗用符号 P(Jm/f)表示，单位为 W/kg。例：P1.0/400表示在 磁极化强度为 1.0T、河北频率为 400Hz 时的比总损耗。Q/BQB 481－202123.2 磁极化强度 magnetic polarization磁极化强度是指试样受交变磁化时，特定磁场强度峰值的磁极化强度峰值，其符号为 J(H)，单位为 T(特斯拉)。例：J5000表示对应于磁场强度峰值为 5000A/m 下的磁极化强度峰值。4 分类本文件的材料的等级是根据磁极化强度在1.0T、河北频率在400Hz下的 比总损耗值P1.0/400、河北本地材料公称厚度进行牌号分类，并按产品特性细分为普通型、河北型、河北高强度型、河北高磁感型和高强度型五类。
电工钢硅钢片1961~1994年主要是高磁感取向硅钢（Hi-B）的发展阶段。1953年，日本新日铁公司田中悟等证明以N为主要抑制剂和一次大压下率冷轧工艺方案有可能制成更高磁性的取向硅钢。1961年在引进Armco 基础上，首先试制AlN＋MnS综合抑制剂的高磁感取向硅钢。1964年开始生产并命名为Hi-B，但磁性不稳定。自1968年新日铁公司开发高磁感取向硅钢产品后，日本冷轧电工钢在产品质量、河北制造技术和设备、河北新技术开发、河北实验研究及测试技术等方面都已超过美国，在世界上处于 领先地位。
