電工鋼硅鋼片硅鋼性能指標電工鋼疊片鐵芯與銅線通過電磁感應做功，鐵芯通過形成交變磁場發(fā)揮作用。鐵芯運行過程中自身耗能和鐵芯磁化能力決定電器設備核心性能，如功率、浙江湖州體積、浙江湖州效率、浙江湖州質量以及綜合運行成本。所以，電工鋼的性能指標要求有下列幾項：1) 鐵芯損耗P：電工鋼鐵芯在勵磁與退磁過程中額外消耗電能轉化成熱量稱為鐵損，單位為W/kg，是劃分產品牌號的主要依據(jù)。鐵損由磁滯損耗Ph、浙江湖州渦流損耗Pe和反常損耗Pa組成。三種鐵損分別與晶粒尺寸、浙江湖州有利織構比例和板帶質量對應。所以，取向和無取向電工鋼中這三種損耗占比不同，如無取向硅鋼的鐵損以Ph為主，取向硅鋼中則以Pe為主。根據(jù)使用條件不同，無取向硅鋼的鐵損保證值取P1.5/50，即硅鋼片在50Hz交變磁場下磁化到1.5T時所消耗的電能，而取向硅鋼相應的鐵損保證值為P1.7/50。

電工鋼硅鋼片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. Since it is a functional material, its performance testing also revolves around "function". These indicators are often mentioned in trade and processing processes, and a brief understanding can help everyone better carry out their work. The performance testing of electrical steel mainly includes the following aspects: magnetic inspection, stacking coefficient inspection, coating adhesion inspection, repeated bending inspection, size and shape surface inspection, and conventional mechanical property inspection. In addition to the types of products 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, which are used as intermediate and intermediate grade High frequency motors and transformers, as well as pulse transformers, etc； 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. Magnetic induction strength is the number of magnetic lines passing through a unit cross-sectional area of the iron core, also known as magnetic flux density. It represents the material‘s magnetization ability, measured in T. The magnetic induction strength of electrical steel plates is high, and the excitation current (also known as no-load current) of the iron core is reduced. Copper and iron losses are also reduced, which can save electrical energy. When the power of the motor and transformer remains constant, the magnetic induction intensity is high, and the design Bm can be increased. The cross-sectional area of the iron core can be reduced, which reduces the volume and weight of the iron core, and saves the amount of electrical steel plates, wires, insulation materials, and structural materials used. This can reduce the total loss and manufacturing cost of the motor and transformer, and is beneficial for the manufacturing, installation, and transportation of large transformers and motors. The main requirements for the performance of silicon steel are: 1. Low iron loss is the most important indicator of the quality of silicon steel sheets. Various countries classify grades based on iron loss values, with the lower the iron loss, the higher the grade. 2. Under strong magnetic fields, the magnetic induction intensity (magnetic induction) is high, which reduces the volume and weight of the iron core of the motor and transformer, saving silicon steel sheets, copper wires, and insulation materials. 3. The surface is smooth, flat, and the thickness is uniform, which can improve the filling coefficient of the iron core. 4. Good lamination performance is more important for manufacturing micro and small electric motors. 5. The adhesion and weldability of the surface insulation film are good, which can prevent corrosion and improve the punching performan
