电工钢硅钢片 电工钢板通常是以铁芯损耗和磁感应强度作为产品磁性保证值[1] [2] 。对电工钢板性能的要求如下:铁芯损耗(PT)低铁芯损耗是指铁芯在≥50Hz交变磁场下磁化时所消耗的无效电能,简称铁损,也称交变损耗,其单位为W/kg。这种由于磁通变化受到各种阻碍而消耗的无效电能,通过铁芯发热既损失掉电能,又引起电机和变压器的温升。电工钢的铁损(PT)包括磁滞损耗、本地涡流损耗(Pe)和反常损耗(Pa)三部分。电工钢板铁损低,既可节省大量电能,又可延长电机和变压器工作运转时间,并简化冷却装置。由于电工钢板的铁损所造成的电量损失占各国全年发电量的2.5%~4.5%,因此各国生产电工钢板总是千方百计设法降低铁损,并以铁损作为考核产品磁性的重要指标,按产品的铁损值作为划分产品牌号的依据。冷轧取向电工钢:冷轧取向电工钢是电工钢中的高端产品,与冷轧无取向电工钢相比,磁性具有强烈的方向性;在易磁化的轧制方向上具有优越的高磁导率与低损耗特性。取向钢带在轧制方向的铁损仅为横向的1/3,磁导率之比为6:1。用途:冷轧取向硅钢带主要的用途是用于变压器制造。
电工钢硅钢片,是电力、电子和军事工业不可缺少的金属材料,亦是产量 的功能性材料,主要用作各种电机、发电机和变压器的铁芯。比总损耗(铁损) specific total loss (iron loss)比总损耗是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:P1.5/50表示在 磁极化强度为 1.5T、频率为 50Hz 时的比总损耗。3.2 磁极化强度 magnetic polarizationQ/BQB 480-20212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1.5T、频率在50Hz下的 比总损耗名义值P1.5/50(W/kg)、材料公称厚度进行牌号分类
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.
