电工钢硅钢片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。全工艺冷轧无取向硅钢涂层:全工艺冷轧硅钢表面涂有一层半透明的绝缘涂层,在不同的标准中有不同的代码,我们以宝钢的Q/BQB 480 2014为例:
电工钢硅钢片一般要求电机、四川泸州当地变压器和其他电器部件效率高,耗电量少,体积小和重量轻。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磁感应强度是铁芯单位截面积上通过的磁力线数,也称磁通密度,它代表材料的磁化能力,单位为T。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、四川泸州当地导线、四川泸州同城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、四川泸州同城安装和运输。

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.
