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.
