0.2取向硅钢B20P075取向硅钢标准

电工钢硅钢片 电工钢板通常是以铁芯损耗和磁感应强度作为产品磁性保证值[1] [2] 。对电工钢板性能的要求如下：铁芯损耗（PT）低铁芯损耗是指铁芯在≥50Hz交变磁场下磁化时所消耗的无效电能，简称铁损，也称交变损耗，其单位为W/kg。这种由于磁通变化受到各种阻碍而消耗的无效电能，通过铁芯发热既损失掉电能，又引起电机和变压器的温升。电工钢的铁损（PT）包括磁滞损耗、本地涡流损耗（Pe）和反常损耗（Pa）三部分。电工钢板铁损低，既可节省大量电能，又可延长电机和变压器工作运转时间，并简化冷却装置。由于电工钢板的铁损所造成的电量损失占各国全年发电量的2.5％~4.5％，因此各国生产电工钢板总是千方百计设法降低铁损，并以铁损作为考核产品磁性的重要指标，按产品的铁损值作为划分产品牌号的依据。冷轧取向电工钢：冷轧取向电工钢是电工钢中的高端产品，与冷轧无取向电工钢相比，磁性具有强烈的方向性；在易磁化的轧制方向上具有优越的高磁导率与低损耗特性。取向钢带在轧制方向的铁损仅为横向的1/3，磁导率之比为6：1。用途：冷轧取向硅钢带主要的用途是用于变压器制造。

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. Taking Baosteel‘s Q/BQB 480 2014 as an example:
