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. Table 2 Classification and Code of Insulation Coatings Type Code Characteristics of Insulation Coatings Semi organic Thin Coating A Improves Punching Performance and Has Good Weldability Semi organic Thick Coating H has Good Punching Performance and High Interlayer Resistance Semi organic Chromium Free Thin Coating K does not contain chromium and has good weldability Semi organic Chromium Free Thick Coating M does not contain chromium and has good insulation performance Semi organic Chromium Free Extreme Thick Coating J does not contain chromium and has excellent insulation performance Semi organic Chromium Free Ultra Thick Coating L does not contain chromium and has extremely high insulation performance Self adhesive Coating
电工钢硅钢片：绝缘涂层状态产品通常以两面涂敷绝缘涂层状态交货，涂层种类见表 2。绝缘涂层应可耐受绝缘漆、湖南本地变压器油、湖南本地机械油等介质的侵蚀。本文件规定的绝缘涂层与国内外相关技术规范规定绝缘涂层的近似对照可参见附录 A(资料性附录)，绝缘涂层的特性见附录 B(资料性附录)。绝缘涂层的厚度、湖南本地自粘接涂层的剥离强度等技术要求如有特殊要求应在订货时协商，并在合同中注明。7.3.2 绝缘涂层附着性根据附录 C（无取向电工钢绝缘涂层附着性检测和评级方法），产品的绝缘涂层的附着性按照由高至低分为 A、湖南本地B、湖南本地C、湖南本地D 四个级别。供货时，产品涂层的附着性级别 应达到 C 级。在剪切过程和供方规定的热处理条件下进行热处理时，涂层不得有大面积脱落，但是在剪切边缘位置，涂层的轻微碎裂则允许存在。7.3.3 涂层绝缘电阻涂层绝缘电阻分为表面绝缘电阻和层间电阻，表面绝缘电阻单位为Ω·cm2/面，层间电阻单位为Ω·cm2/片，理论上，层间电阻是表面绝缘电阻的 2 倍。根据需方要求，经供需双方协商，可进行涂层绝缘电阻的检测，并在合同中注明涂层表面绝缘电阻或层间电阻的小值。
