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.

电工钢硅钢片我国太原钢铁厂于1952年首先试制热轧低硅钢板（1％~2％Si），1954年正式生产。1957年由钢铁研究总院研制成功3％Si冷轧取向硅钢，到1973年我国已掌握Armco技术 要点，鞍钢进行试制但未能生产。1974年武汉钢铁公司从日本新日铁引进冷轧取向硅钢制造装备和 。1976~1977年，钢铁研究总院在验证和消化日本 的基础上开发了Hi-B取向硅钢。1979年武钢正式生产取向硅钢，到目前为止武钢仍是我国取向硅钢的主要生产基地。

电工钢硅钢片半有机无铬超厚涂层L C6 C-6 EC-6 C-7涂层以有机成分为基础，添加较多的无机填料，以提高涂层绝缘性。涂层通常用于全工艺无取向电工钢，特别是大直径电机，如电站发电机。涂层可以改善钢的冲片性能，适合冲压叠片。涂层具有较高的层间电阻，能承受 300-550℃的涂层烧除处理，可用于重建电机定子时，去除电机定子绕组的绝缘层，也可用于风冷式或油浸式。涂层不能承受正常的应力退火。用户选择该涂层时，应考虑到在焊接过程中或涂层用于高温环境时，涂层会分解放出气体的情况。用户可以和供方协商确定该类涂层的层间电阻范围
