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機(jī)、發(fā)電機(jī)、變壓器、扼流圈、電磁機(jī)構(gòu)、繼電器及測量儀表中電機(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、直流電動機(jī);冷軋無取向硅鋼片厚度為0.35~0.50mm,密度為7.65~7.75g/cm3,多用于大型交流發(fā)電機(jī)、電動機(jī),大、中、小型交、直流電動機(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,多用于無線電高頻變壓器。



電工鋼硅鋼片應(yīng)力退火電工鋼在剪切、福建漳州同城沖片和彎曲加工等機(jī)械變形作用下,電磁性能將發(fā)生劣化。為此進(jìn)行應(yīng)力退火,可以使電工鋼的電磁性能恢復(fù)至原來水平。應(yīng)力退火的條件和工藝將根據(jù)加工程度、福建漳州同城退火爐況等有明顯不同,用戶務(wù)必注意如下幾點(diǎn):(1) 加熱與冷卻速度電磁性能一般不受加熱和冷卻速度的影響,但用戶需確保材料不變形。(2)退火溫度與保溫時間取向電工鋼退火溫度在780-820℃之間較為適宜,為確保退火效果,退火材料應(yīng)均熱的保持,保溫時間應(yīng)根據(jù)鐵芯形狀、福建漳州同城裝爐量等進(jìn)行調(diào)整。(3)防止?jié)B碳與氧化由于滲碳及氧化會使電磁性能劣化,用戶應(yīng)充分注意爐內(nèi)氣體,并確保爐內(nèi)氣體的露點(diǎn)在較低狀態(tài)。另外,為防止在退火中發(fā)生滲碳,應(yīng)該在退火前,將鐵芯加工過程中潤滑油脂等有機(jī)化合物干凈。同時,為確保退火效果,建議與爐內(nèi)高溫接觸部分盡量采用低碳含量材料。有害物質(zhì)限定承諾 寶鋼的取向電工鋼產(chǎn)品符合RoHS、福建漳州同城REACH有害物質(zhì)限定要求。




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. Specific total loss (iron loss) is the total power consumed per unit mass of material when the magnetic polarization waveform remains sinusoidal, with a specific peak and frequency. The specific total loss is represented by the symbol P (Jm/f), in W/kg. Example: P1.5/50 represents the specific total loss at a maximum magnetic polarization intensity of 1.5T and a frequency of 50Hz. 3.2 Magnetic Polarization Q/BQB 480-20212 Magnetic polarization intensity refers to the peak magnetic polarization intensity of a specific magnetic field intensity when a sample is subjected to alternating magnetization. Its symbol is J (H), and the unit is T (Tesla). Example: J5000 represents the peak magnetic polarization intensity corresponding to a magnetic field intensity peak of 5000A/m. The material grades in this document are classified based on the nominal maximum specific total loss P1.5/50 (W/kg) at a magnetic polarization strength of 1.5T and a frequency of 50Hz, as well as the nominal thickness of the material. They are further divided into three categories based on product characteristics: ordinary type, stress relief annealing type, and high-efficiency type. Example 1: B35A210 represents a common non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 2.10W/kg; Example 2: B35AR300 represents a stress relieved annealed non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 3.00W/kg; Example 3: B35AH230 represents an efficient non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg. Example 4: 35WW210 represents a normal type WW non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.10W/kg. Example 5: 35WH230 represents an efficient WH non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg.
