冷扎硅钢片性能数据表

式中: K D—铁心直径经验系数, 对冷轧硅钢片的铁心及铜绕组的变压器, 一般取K D = 52～57 , 对特大型变压器, 由于运输高度的限制, 此经验系数有时取得还要大些;q j — 接缝磁化容量(VA/cm 2),根据斜接缝处磁密(),从表1.3或表1.4中选取; P r — 额定容量( kVA );K I 0 — 空载电流附加系数, 铁心为全斜接缝时, 从表1.2 中选取。

表1.2 附加系数 ( 铁心为全斜接缝时 )注: ①三相五柱式等轭是指主轭和旁轭截面相等, 不等轭是指主轭和旁轭截面不相等。

6 冷轧硅钢片性能数据冷轧硅钢片性能数据,可按表 1.3公式计算, 或直接从表 1.4 中选取。

2/B B m mj角重是指边柱中心线外侧铁轭四个角的重量及心柱与铁轭各级填补的重量（如图1.2中阴影部分所示）。

标准铁心的角重, 具体数据可从表1.5至表1.7查得, 下面仅以三相变压器为例, 计算其角重。

图1.2 铁心角重计算示意图p tx—铁心硅钢片单位损耗(W /kg ),ρ tx —铁心硅钢片密度( g / cm3 ) , 冷轧硅钢片取ρ tx = 7.65 g / cm3 ;f d —铁心叠片系数, 从表1.1中选取, 采用冷轧硅钢片35Z155时, f d = 0.97 ; S jk—铁心级块毛截面积( cm2 );b m—铁心级块中的最大片宽( cm ) ;δm—铁心级块(铁心中两个油道之间或油道至最外级间)的总厚度( cm ) ; m—修正系数。

最外部级块(油道至最外级间的级块) : m = 1 ;中间级块: 当δm≤7.5 cm 时: m = 1 ;当δm≥20 c m 时: m = 0.5 ;当7.5 <δm< 20 cm 时: m = 1.3 －0.04 δm( 1.15 )摘要本设计是以亚东亚变压器公司SFSZ-4000/110型变压器铁心为设计题目，主要任务是使得变压器在运行过程中的减少能耗和减小噪声。

硅钢片参数及型号一、介绍硅钢片是一种用途广泛的特殊材料，它具有低磁性、高电阻和高磁导率的特点。

在电力、电子和通信等领域中，硅钢片被广泛应用于制造电机、变压器和感应器等电动设备。

为了满足不同应用的需求，硅钢片拥有各种不同的型号和参数。

本文将详细讨论硅钢片的参数及型号，帮助读者更好地了解和选择合适的硅钢片。

二、硅钢片的关键参数硅钢片的关键参数主要包括矫顽力、最大磁通密度、电阻率和铁心损耗。

下面将对每个参数进行详细说明。

1. 矫顽力矫顽力是硅钢片的一个重要参数，它表示材料在磁场作用下磁化所需的磁场强度。

矫顽力越低，硅钢片的磁导率就越高，磁化能力越强。

一般情况下，矫顽力的单位为A/m，硅钢片的矫顽力通常在1.5 - 2.2 A/m之间。

2. 最大磁通密度最大磁通密度是指硅钢片饱和时的磁通密度。

磁通密度越大，表示硅钢片具有更高的磁导率和磁化能力。

最大磁通密度的单位通常为T（特斯拉），硅钢片的最大磁通密度一般在1.5 - 2.0 T之间。

3. 电阻率硅钢片的电阻率是指单位长度内材料的电阻值。

电阻率越高，表明硅钢片的电阻性能越好，损耗越小。

电阻率的单位通常为Ω·m（欧姆·米），硅钢片的电阻率一般在50 - 130 μΩ·m之间。

4. 铁心损耗铁心损耗是硅钢片在交变磁场中产生的能量损耗。

它包括涡流损耗和磁滞损耗两部分。

铁心损耗越小，表明硅钢片具有更好的能量传导和转换效率。

铁心损耗的单位通常为W/kg（瓦特/千克），硅钢片的铁心损耗一般在0.5 - 5 W/kg之间。

三、硅钢片的型号分类根据硅钢片的用途和性能要求的不同，硅钢片可以分为多种不同的型号。

1.硅钢片参数介绍硅钢片的主要参数包括：铁损、磁感应强度、磁导率、饱和磁密、居里点等。

其中，铁损是指硅钢片在交变磁场中产生的热量，它与硅钢片的磁滞损耗和涡流损耗有关；磁感应强度是指硅钢片在外加磁场下的磁化强度；磁导率是指硅钢片在磁场中的磁化程度；饱和磁密是指硅钢片在磁场作用下磁化强度达到最大值时的磁场强度；居里点是指硅钢片在高温下保持磁性的温度。

2.M400-5A 硅钢片的具体参数M400-5A 硅钢片是一种常见的硅钢片型号，其具体参数如下：- 铁损：≤1.5W/kg- 磁感应强度：≥1.75T- 磁导率：≥400- 饱和磁密：≤2.15T- 居里点：≥340℃这些参数保证了M400-5A 硅钢片在电机中具有良好的磁性能和低的损耗。

3.硅钢片在电机中的应用硅钢片在电机中主要应用于定子和转子。

定子硅钢片通常采用冷轧硅钢片，其厚度一般在0.35-2mm 之间，用于制造电机的铁芯。

转子硅钢片通常采用热轧硅钢片，其厚度一般在2-6mm 之间，用于制造电机的转子。

硅钢片的选择和使用应根据电机的具体参数和性能要求进行。

4.硅钢片的选择和使用建议在选择硅钢片时，应根据电机的功率、电压、频率、工作环境等参数，选择合适的硅钢片型号和参数。

在使用硅钢片时，应注意防止硅钢片受潮、变形和损坏，避免高温和长时间暴露在阳光下。

同时，应定期检查硅钢片的性能，如有损坏应及时更换。

矽钢片的好坏取决于矽钢片的材质和加工工艺，EI型矽钢片的加工工艺最重要。

它直接影响变压器的质量，加工工艺中的冲压方法，退火方法最重要，同一材质的矽钢片冲压毛刺小的与毛刺大的制作的变压器性能差7%，同一材质的矽钢片退后（氮气保护退火）与不退火的矽钢片制作的变压器性能相差7-10%国内常用的H系列编号，是沿用70年代-90年代的日本新日铁的标号。

而现在正规厂家都按照新的标号标示。

但是产量很少，一般用于要求较高的场合。

另外同一牌号有白片黑片之分，黑片{退火片}性能优于白片。

另外同一牌号铁芯尺寸不同性能也不同。

有取向硅钢带常用的牌号有Z11 Z10比重7.65 7.65铁损P1.7/50 ≤ 1.66 1.51磁通密度B10≥ 1.74 1.77日本jfe(旧川崎):35jn250 (0.35mm厚、铁损在2.18～2.26之间、磁感1.69以上)50jn270 (0.50mm厚、铁损在2.38～2.42之间、磁感1.68以上)50jn290 (0.50mm厚、铁损在2.46～2.51之间、磁感1.68以上)50jn310 (0.50mm厚、铁损在2.50～2.54之间、磁感1.69以上)日本新日铁:50h270 (0.50mm厚、铁损在2.37～2.41之间、磁感1.68以上)50h290 (0.50mm厚、铁损在2.46～2.50之间、磁感1.68以上)50h310 (0.50mm厚、铁损在2.49～2.53之间、磁感1.69以上)中国太钢:50tw290 (0.50mm厚、铁损在2.54～2.60之间、磁感1.68以上)50tw310 (0.50mm厚、铁损在2.64～2.69之间、磁感1.68以上)50tw350 (0.50mm厚、铁损在2.70～2.76之间、磁感1.69以上)中国牌号表示方法：（1）冷轧无取向硅钢带（片）表示方法：DW+铁损值（在频率为50HZ，波形为正弦的磁感峰值为1.5T的单位重量铁损值。

硅钢片的性能及化学成分sheets，它是一种含碳极低的硅铁软磁合金,一般含硅量为0、5～4、5％。

加入硅可提高铁的电阻率和最大磁导率,降低矫顽力、铁芯损耗（铁损）和磁时效。

硅钢片主要用来制作各种变压器、电动机和发电机的铁芯。

世界硅钢片产量约占钢材总量的1%（见精密合金）。

对硅钢性能的要求主要是：①铁损低，这是硅钢片质量的最重要指标。

各国都根据铁损值划分牌号，铁损愈低，牌号愈高。

②较强磁场下磁感应强度（磁感）高，这使电机和变压器的铁芯体积与重量减小，节约硅钢片、铜线和绝缘材料等。

③表面光滑、平整和厚度均匀，可以提高铁芯的填充系数。

④冲片性好，对制造微型、小型电动机更为重要。

⑤表面绝缘膜的附着性和焊接性良好，能防蚀和改善冲片性。

⑥基本无磁时效。

典型电磁性能见表1。

硅钢片硅钢片一般随硅含量提高，铁损、冲片性和磁感降低，硬度增高。

工作频率愈高,涡流损耗愈大,选用的硅钢片应当愈薄。

冶炼和轧制硅钢主要用氧气转炉冶炼（也可用电弧炉冶炼）,配合钢水真空处理和AOD技术（见炉外精炼，采用模铸或连铸法。

根据不同的用途,冶炼时改变硅(0、5～4、5%)和铝(0、2～0、5%)含量以满足不同磁性的要求。

高牌号硅钢片的硅和铝量相应提高。

碳、硫和夹杂物尽量减少。

冷轧硅钢片的磁性、表面质量、填充系数和冲片性比热轧硅钢片好，并可成卷生产，所以从60年始有些国家已停止生产热轧硅钢片。

中国采用约900℃低温一次快速热轧和氢气保护下成垛退火方法制造热轧硅钢片，成材率较高，成品表面质量和磁性都较好。

硅钢片冷轧无取向硅钢片冷轧无取向硅钢片是将钢坯或连铸坯热轧成厚度约2、3mm带卷。

制造低硅产品时,热轧带卷酸洗后一次冷轧到 0、5mm厚。

制造高硅产品时，热轧带酸洗后（或先经800～850℃常化后再酸洗）,冷轧到0、55或0、37mm厚,在氢氮混合气氛连续炉中850℃退火，再经6～10%小压下率冷轧到0、50或0、35mm厚。

这个小压下率的冷轧可使退火时晶粒长大，铁损降低。

常用硅钢片牌号主要包括以下几种：
1. 冷轧无取向硅钢带（片）：
表示方法：DW铁损值（在频率为50HZ，波形为正弦的磁感峰值为1.5T的单位重量铁损值。

）的100倍厚度值的100倍。

常用牌号：50W470、47W50、45W45、43W43等。

2. 冷轧取向硅钢带（片）：
表示方法：DQ铁损值（在频率为50HZ，波形为正弦的磁感峰值为1.7T的单位重量铁损值。

）的100倍厚度值的100倍。

有时铁损值后加G表示高磁感。

如DQ133-30表示铁损值为1.33，厚度为0.3mm的冷轧取向硅钢带。

常用牌号：30Q133、40Q140、50Q150等。

3. 热轧硅钢板：

如DR510-50表示铁损值为5.1，厚度为0.5mm的热轧硅钢板。

常用牌号：DR510、DR410、DR310等。

4. 电机用硅钢片：
表示方法：根据电机性能和用途不同，有不同的表示方法。

如470、600、800等，分别表示铁损值为4.7w/kg、6.0w/kg、8.0w/kg的硅钢片。

常用牌号：470、600、800等。
