电工钢硅钢片电工钢板的磁感应强度高，铁芯的激磁电流（也称空载电流）降低，铜损和铁损都下降，可节省电能。当电机和变压器功率不变时，磁感应强度高，设计Bm可提高，铁芯截面积可缩小，这使铁芯体积减小和重量减轻，并节省电工钢板、青海果洛导线、青海果洛绝缘材料和结构材料用量，可降低电机和变压器的总损耗和制造成本，并且有利于大变压器和大电机的制造、青海果洛安装和运输。硅钢性能的要求主要是：1、青海果洛铁损低，这是硅钢片质量的重要指标。各国都根据铁损值划分牌号，铁损愈低，牌号愈高。2、青海果洛较强磁场下磁感应强度（磁感）高，这使电机和变压器的铁芯体积与重量减小，节约硅钢片、青海果洛铜线和绝缘材料等。3、青海果洛表面光滑、青海果洛平整和厚度均匀，可以提高铁芯的填充系数。4、青海果洛冲片性好，对制造微型、青海果洛小型电动机更为重要。5、青海果洛表面绝缘膜的附着性和焊接性良好，能防蚀和改善冲片性
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.
