電工鋼硅鋼片硅鋼是一種硅鐵合金。用硅鋼軋制的片材是電工領(lǐng)域中應(yīng)用廣的軟磁材料，因而硅鋼片又稱電工鋼片。硅鋼片廣泛用于電動(dòng)機(jī)、發(fā)電機(jī)、變壓器、扼流圈、電磁機(jī)構(gòu)、繼電器及測(cè)量?jī)x表中電機(jī)工業(yè)大量使用厚度為0.35～0.50mm的硅鋼片,用于：中型旋轉(zhuǎn)機(jī)，壓縮電機(jī)，通用馬達(dá)，小型精密電機(jī)，電動(dòng)汽車，壓縮機(jī)，通用電機(jī)，電源變壓器，精密變壓器，節(jié)能電機(jī)，焊機(jī)變壓器，穩(wěn)壓器，磁性密封器，加速器用電磁鐵，汽車電機(jī)等；在電信高頻技術(shù)中常用0.05~0.20mm的薄帶鋼片,以便更有效地降低渦流損耗。熱軋硅鋼片厚度為0.35～0.50mm，密度為7.55～7.70g/cm3,多用于大、中、小型交、直流電動(dòng)機(jī)；冷軋無(wú)取向硅鋼片厚度為0.35～0.50mm，密度為7.65～7.75g/cm3，多用于大型交流發(fā)電機(jī)、電動(dòng)機(jī)，大、中、小型交、直流電動(dòng)機(jī)；冷軋取向硅鋼片厚度為0.23mm 0.27mm 0.3mm 0.35mm，密度為7.65g/cm3,多用于電力變壓器、油浸式變壓器，干式變壓器，電抗器、磁放大器等；冷軋取向薄帶厚度為0.05～0.20mm，多用于無(wú)線電高頻變壓器。

電工鋼硅鋼片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.

電工鋼硅鋼片 電工鋼板通常是以鐵芯損耗和磁感應(yīng)強(qiáng)度作為產(chǎn)品磁性保證值[1] [2] 。對(duì)電工鋼板性能的要求如下：鐵芯損耗（PT）低鐵芯損耗是指鐵芯在≥50Hz交變磁場(chǎng)下磁化時(shí)所消耗的無(wú)效電能，簡(jiǎn)稱鐵損，也稱交變損耗，其單位為W/kg。這種由于磁通變化受到各種阻礙而消耗的無(wú)效電能，通過(guò)鐵芯發(fā)熱既損失掉電能，又引起電機(jī)和變壓器的溫升。電工鋼的鐵損（PT）包括磁滯損耗、浙江麗水本地渦流損耗（Pe）和反常損耗（Pa）三部分。電工鋼板鐵損低，既可節(jié)省大量電能，又可延長(zhǎng)電機(jī)和變壓器工作運(yùn)轉(zhuǎn)時(shí)間，并簡(jiǎn)化冷卻裝置。由于電工鋼板的鐵損所造成的電量損失占各國(guó)全年發(fā)電量的2.5％~4.5％，因此各國(guó)生產(chǎn)電工鋼板總是千方百計(jì)設(shè)法降低鐵損，并以鐵損作為考核產(chǎn)品磁性的重要指標(biāo)，按產(chǎn)品的鐵損值作為劃分產(chǎn)品牌號(hào)的依據(jù)。冷軋取向電工鋼：冷軋取向電工鋼是電工鋼中的高端產(chǎn)品，與冷軋無(wú)取向電工鋼相比，磁性具有強(qiáng)烈的方向性；在易磁化的軋制方向上具有優(yōu)越的高磁導(dǎo)率與低損耗特性。取向鋼帶在軋制方向的鐵損僅為橫向的1/3，磁導(dǎo)率之比為6：1。用途：冷軋取向硅鋼帶主要的用途是用于變壓器制造。
