电工钢硅钢片近20年来，我国硅钢产业取得了长足的进步，这其中以首钢、湖北随州当地武钢和宝钢为代表。得益于我国钢铁行业全流程的技术进步，这些企业在控制无取向硅钢整体质量稳定性和取向硅钢方面已经具有较高技术实力。2014年我国硅钢生产达到823万吨，高端产品有20~30万吨的进口量，2015年，我国共生产电工钢约836万吨，进口量进一步下降到14万吨。但是，与日本相比我国在高端电工钢领域仍有不小的差距，这集中体现在高磁感无取向硅钢、湖北随州当地超低铁损Hi-B取向硅钢和高硅钢等产品上。例如，新日铁公司(现新日铁住金)能够实现0.15~0.35mm系列厚度规格极低铁损Hi-B取向电工钢的稳定供货，引领取向硅钢工艺发展。在特殊用途硅钢方面，日本钢管公司(现JFE)通过气相沉积法(CVD)渗硅的方式实现了高硅钢薄带的供货。随着我国装备制造业的产业升级，高端硅钢产品的需求会越来越迫切。我国与日韩等钢铁强国在这一领域的竞争将会更加激烈，这就要求我国相关科研人员通过革命性创新进行下一代硅钢生产技术的研发，引领世界电工钢技术的发展。低铁损、湖北随州当地高磁感电机用无取向硅钢、湖北随州当地薄规格超低铁损高磁感取向硅钢和中高频节能电器用高硅钢是电工钢产业的发展方向。

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.
