电工钢硅钢片硅钢是一种硅铁合金。用硅钢轧制的片材是电工领域中应用广的软磁材料,因而硅钢片又称电工钢片。硅钢片广泛用于电动机、发电机、变压器、扼流圈、电磁机构、继电器及测量仪表中电机工业大量使用厚度为0.35~0.50mm的硅钢片,用于:中型旋转机,压缩电机,通用马达,小型精密电机,电动汽车,压缩机,通用电机,电源变压器,精密变压器,节能电机,焊机变压器,稳压器,磁性密封器,加速器用电磁铁,汽车电机等;在电信高频技术中常用0.05~0.20mm的薄带钢片,以便更有效地降低涡流损耗。热轧硅钢片厚度为0.35~0.50mm,密度为7.55~7.70g/cm3,多用于大、中、小型交、直流电动机;冷轧无取向硅钢片厚度为0.35~0.50mm,密度为7.65~7.75g/cm3,多用于大型交流发电机、电动机,大、中、小型交、直流电动机;冷轧取向硅钢片厚度为0.23mm 0.27mm 0.3mm 0.35mm,密度为7.65g/cm3,多用于电力变压器、油浸式变压器,干式变压器,电抗器、磁放大器等;冷轧取向薄带厚度为0.05~0.20mm,多用于无线电高频变压器。

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:
