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.

电工钢硅钢片硅钢是一种硅铁合金。用硅钢轧制的片材是电工领域中应用广的软磁材料,因而硅钢片又称电工钢片。硅钢片广泛用于电动机、发电机、变压器、扼流圈、电磁机构、继电器及测量仪表中电机工业大量使用厚度为0.35~0.50mm的硅钢片,用于:中型旋转机,压缩电机,通用马达,小型精密电机,电动汽车,压缩机,通用电机,电源变压器,精密变压器,节能电机,焊机变压器,稳压器,磁性密封器,加速器用电磁铁,汽车电机等;在电信高频技术中常用0.05~0.20mm的薄带钢片,以便更有效地降低涡流损耗。热轧硅钢片厚度为0.35~0.50mm,密度为7.55~7.70g/cm3,多用于大、中、小型交、直流电动机;冷轧无取向硅钢片厚度为0.35~0.50mm,密度为7.65~7.75g/cm3,多用于大型交流发电机、电动机,大、中、小型交、直流电动机;冷轧取向硅钢片厚度为0.23mm 0.27mm 0.3mm 0.35mm,密度为7.65g/cm3,多用于电力变压器、油浸式变压器,干式变压器,电抗器、磁放大器等;冷轧取向薄带厚度为0.05~0.20mm,多用于无线电高频变压器。




电工钢硅钢片半有机无铬薄涂层K H4 C-5 EC-5-P C-6涂层通常以磷酸盐无机成分为主,添加少量有机成分,不含有铬元素,杜绝了用户退火、辽宁本溪本地发蓝和使用过程中发生六价铬含量超标的可能性,性、辽宁本溪本地环保性 。性能基本接近A 涂层,绝缘性好,冲片性好,在中性气氛或弱还原性炉子气氛中,可承受的应力退火温度一般可达800℃,在退火时,层间电阻会有一定降低。半有机无铬厚涂层M --- C-5 EC-5-P C-6涂层基本情况和 K 涂层类似,膜厚增加,绝缘性更好,耐蚀性更好,冲片性也更好,焊接性略差。



电工钢硅钢片 在进行马达设计的时候,定转子的涡流损耗是无法规避的问题,高性能和高转速马达对于铁损及马达的效率更为敏感,因此如何降低其铁损成为了主要考虑的因素,除了选择更薄的硅钢片作为主要的设计思路之外,如何避免硅钢片的层间绝缘导通而产生的涡流损耗成了重要的考虑,而定转子散片胶粘技术成为了 的解决方案,因为传统的铆接自扣和焊接都无法从根本上杜绝这种硅钢片的层间导通;佰思特通过多年的技术研发,开发出符合铁芯定子产品的胶粘工艺以满足批量生产的需求
