电工钢硅钢片：供货形式产品以卷供货，简称钢卷。当订货合同中未注明边缘状态时，产品按切边状态供货。6.2.1 钢卷的重量应符合订货要求，卷重一般为 2.00～6.00 吨。6.2.2 钢卷通常以切边状态交货。用户有特殊要求时，通过协议可以以不切边状态交货。6.2.3 钢卷内径应在 500mm～520mm 范围内，内径值为 508±5mm。6.2.4 钢卷应由同一宽度的钢带连续、本地紧密卷绕，卷的侧面应尽量平直，自重下不塌卷。Q/BQB 485－202156.2.5 产品可能由于去除缺陷而产生接带或焊缝，接带或焊缝处应作标记，接带或焊缝前后部分应为同一牌号，且不超过 2 处，焊缝间钢带长度应不小于 200 米。6.2.6 除无涂层系列产品之外，产品两面涂有绝缘涂层。6.2.7 用户有特殊要求时，应符合订货协议。
电工钢硅钢片自粘接涂层Z C3 C-3 - C-3涂层为有机成分，具有很高的层间电阻，并可以大幅提高钢带的冲片性能，很适合用于冲压叠片。用户使用时，先将钢板冲制成铁心叠片，然后加压固定成型，在保压条件下加热固化，叠片彼此粘接在一起，形成整体。其固定方式和常见的铆接、同城焊接、同城螺栓方式不同，刚度、同城强度更高，振动和噪音小。涂层交货状态为 B 状态，即涂层还没有发生完全固化，具有进一步粘接、同城固化的活性，涂层硬度、同城耐蚀性尚没有达到 。涂层钢卷仓储有效期为半年。用户固化的工艺为：a）炉烘温度 160～230℃，模具压紧的压力为 0.3～3Mpa，时间保持1～3h；或 b）感应固化的铁心温度 150~250℃，压力 0.1~3MPa，时间保持 0.2~30min。固化后，涂层处于终稳定的状态，即 C 状态，涂层硬度、同城强度、同城粘接力达到 。涂层不能承受正常的应力退火温度。涂层能承受 180℃的长期耐热温度；但考虑到粘结能力的稳定性，适用于该涂层的工作温度通常不超过 150℃。
电工钢硅钢片In addition to the types listed above, there are also some special purpose electrical steel plates, such as 0.15 and 0.20mm thick 3％ Si cold-rolled non oriented silicon steel strips and 0.025, 0.05, and 0.1mm thick 3％ Si cold-rolled oriented silicon steel strips, used for medium and high-frequency motors, transformers, and pulse transformers； 0.7mm thick 3％ Si high-strength cold-rolled non oriented silicon steel plate for relays and power switches； High strength cold-rolled electrical steel plate for new high-speed motor rotors； Low carbon electrical steel hot-rolled thick and cold-rolled plates for magnetic shielding and high-energy accelerator electromagnets such as medical magnetic resonance tomography scanners； 4.5％ to 6.5％ Si high silicon steel plates for high-frequency motors, transformers, and magnetic shielding.Generally, motors, transformers, and other electrical components are required to have high efficiency, low power consumption, small size, and light weight. Electrical steel plates are usually guaranteed to have magnetic properties based on core loss and magnetic induction strength [1] [2]. The requirements for the performance of electrical steel plates are as follows:Low core loss (PT)Iron core loss refers to the ineffective electrical energy consumed by an iron core when magnetized in an alternating magnetic field of ≥ 50Hz, abbreviated as iron loss, also known as alternating loss, and its unit is W/kg. The ineffective electrical energy consumed due to various obstacles caused by magnetic flux changes not only loses electrical energy through the heating of the iron core, but also causes temperature rise of the motor and transformer. The iron loss (PT) of electrical steel includes three parts: hysteresis loss, eddy current loss (Pe), and anomalous loss (Pa). Electrical steel plates have low iron loss, which can save a lot of electricity, prolong the operating time of motors and transformers, and simplify cooling devices. Due to the iron loss of electrical steel plates, which accounts for 2.5％ to 4.5％ of the annual electricity generation in various countries, countries always try their best to reduce iron loss in the production of electrical steel plates, and use iron loss as the most important indicator to assess the magnetic properties of products. The iron loss value of products is used as the basis for classifying product grades. Cold rolled oriented electrical steel: Cold rolled oriented electrical steel is a high-end product in the field of electrical steel. Compared with cold rolled non oriented electrical steel, its magnetism has strong directionality； It has superior high magnetic permeability and low loss characteristics in the direction of easy magnetization rolling. The iron loss of oriented steel strip in the rolling direction is only 1/3 of that in the transverse direction, and the ratio of magnetic permeability is 6:1. Application: The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing.Full process cold rolled non oriented silicon steel coating: The surface of the full process cold rolled silicon steel is coated with a semi transparent insulation coating, which has different codes in different standards.
