Description
本发明涉及生产表现出磁特性的Fe-Si电工钢板的方法。这种材料例如用于制造用于车辆的电动机的转子和/或定子。
赋予Fe-Si钢磁特性是最经济的磁感应源。从化学组成的观点来看,向铁添加硅是增加电阻率的非常常用的方式,因此改善了磁特性,并且同时减小了总的功率损耗。目前共存的用于电气设备的钢的构造的两类为:晶粒取向钢和非晶粒取向钢。
非晶粒取向钢具有在所有磁化方向上拥有几乎相等的磁特性的优点。因此,这种材料更适用于需要旋转运动的应用,例如马达或发电机。
以下特性用于评估电工钢的就磁特性而言的效率:
-磁感应,以特斯拉表示。该感应是在以A/m表示的特定磁场下获得的。磁感应越高越好。
-磁芯功率损耗,以W/kg表示,磁芯功率损耗在以特斯拉(T)表示的特定极化下使用以赫兹表示的频率测量。总的损耗越低越好。
许多冶金参数可能会影响上述特性,最常见的冶金参数是:合金含量、材料织构、铁素体晶粒尺寸、析出物尺寸及分布、以及材料厚度。自此,从铸造至最终经冷轧的钢退火的热机械处理对于达到目标规格是至关重要的。
JP201301837公开了生产电磁钢板的方法,其包括0.0030%或更小的C、2.0-3.5%的Si、0.20-2.5%的Al、0.10-1.0%的Mn和0.03-0.10%的Sn,其中,Si+Al+Sn≤4.5%。对这种钢进行热轧,然后以60-70%的轧制率进行初步冷轧,以生产具有中等厚度的钢板。然后,对钢板进行中间退火,然后以55-70%的轧制率进行二次冷轧,并且进一步在950℃或更高的温度下进行最终退火持续20秒至90秒。这种方法相当消耗能量,并且涉及长的生产路线。
JP2008127612涉及非晶粒取向电磁钢板,其具有包括以质量%计的以下化学组成:0.005%或更小的C、2%至4%的Si、1%或更小的Mn、0.2%至2%的Al、0.003%至0.2%的Sn、余量为Fe和不可避免的杂质。厚度为0.1mm至0.3mm的非晶粒取向电磁钢板通过以下步骤制造:在中间退火步骤之前和之后对经热轧的板进行冷轧,随后对板进行再结晶退火。这样的处理路线如同用于不利于生产率的第一种应用的处理路线,这是由于其涉及了长的生产路线。
似乎仍需要生产这种FeSi钢的方法,该方法将简化并且更加稳健,而不包括功率损耗和感应性能。
根据本发明的钢遵循简化的生产路线以达到功率损耗和感应的良好折衷。此外,工具磨损由根据本发明的钢来限制。
本发明的目的在于提供生产经退火经冷轧的非晶粒取向Fe-Si钢板的方法,该方法包括以下顺序步骤:
-使包含以重量百分比计的以下元素的钢组合物熔化:
C≤0.006
2.0≤Si≤5.0
0.1≤Al≤3.0
0.1≤Mn≤3.0
N≤0.006
0.04≤Sn≤0.2
S≤0.005
P≤0.2
Ti≤0.01
余量为Fe和不可避免的杂质,
-将所述熔体铸造成板坯,
-在1050℃与1250℃之间的温度下对所述板坯进行再加热,
-用750℃与950℃之间的热轧终止温度对所述板坯进行热轧以获得经热轧的钢带,
-在500℃与750℃之间的温度下对所述经热轧的钢带进行卷取,以获得热带
-任选地,在650℃与950℃之间的温度下将经热轧的钢带退火持续
10秒与48小时之间的时间,
-对经热轧的钢带进行冷轧以获得经冷轧的钢板,
-将经冷轧的钢板加热至850℃与1150℃之间的均热温度,
-将经冷轧的钢板保持在均热温度下持续20秒与100秒之间的时间,
-将经冷轧的钢板冷却至室温,以获得经退火经冷轧的钢板。
在优选的实施方案中,根据本发明的生产非晶粒取向Fe-Si钢板的方法的硅含量使得2.0≤Si≤3.5,甚至更优选地2.2≤Si≤3.3。
在优选的实施方案中,根据本发明的生产非晶粒取向Fe-Si钢板的方法的铝含量使得:0.2≤Al≤1.5,甚至更优选地0.25≤Al≤1.1。
在优选的实施方案中,根据本发明的生产非晶粒取向Fe-Si钢板的方法的锰含量使得:0.1≤Mn≤1.0。
优选地,根据本发明的生产非晶粒取向Fe-Si钢板的方法的锡含量使得:0.07≤Sn≤0.15,甚至更优选地0.11≤Sn≤0.15。
在另一优选的实施方案中,根据本发明的生产非晶粒取向Fe-Si钢板的方法涉及任选的热带退火使用连续退火线进行。
在另一优选的实施方案中,根据本发明的生产非晶粒取向Fe-Si钢板的方法包括任选的热带退火使用分批退火进行。
在优选的实施方案中,均热温度在900℃与1120℃之间。
在另一实施方案中,根据本发明的非晶粒取向的经冷轧经退火的钢板被涂覆。
本发明的另一目的是使用本发明的方法获得的非晶粒取向钢。
本发明的目的还为使用根据本发明生产的非晶粒取向钢的高效率工业马达、用于电力生产的发电机、用于电动车辆的马达,以及使用根据本发明生产的非晶粒取向钢的用于混合动力车辆的马达。
为了达到所期望的特性,根据本发明的钢包括以重量百分比计的以下化学组成元素:
碳量限制于0.006,且0.006包括在内。该元素可以是有害的,由于碳能够引起钢的老化和/或析出,这将会使磁特性劣化。因此,浓度应限制为低于60ppm(0.006wt%)。
Si的最小含量为2.0%,同时Si的最大含量限制为5.0%,且两个端值包括在内。Si在增加钢的电阻率方面起主要作用,因此降低涡流损耗。低于2.0wt%的Si,难以实现低损耗等级的损耗水平。高于5.0wt%的Si,钢变脆并且随后的工业处理变得困难。因此,Si含量为使得:2.0wt%≤Si≤5.0wt%,在优选实施方案中,2.0wt%≤Si≤3.5wt%,甚至更优选地,2.2wt%≤Si≤3.3wt%。
铝含量应在0.1%与3.0%之间,且两个端值均包括在内。在电阻率效应方面,该元素以与硅所起作用的方式类似的方式起作用。低于0.1wt%的Al,对电阻率或损耗没有实际影响。高于3.0wt%的Al,钢变脆并且随后的工业处理变得困难。因此,Al含量为使得:0.1wt%≤Al≤3.0wt%,在优选实施方案中,0.2wt%≤Al≤1.5wt%,甚至更优选地,0.25wt%≤Al≤1.1wt%。
锰含量应在0.1%与3.0%之间,且两个端值均包括在内。对于电阻率,该元素以与Si或Al所起作用的方式类似的方式起作用:锰增加电阻率,因此降低涡流损耗。另外,Mn有助于使钢硬化,并且可对需要较高机械特性的等级有用。低于0.1wt%的Mn,对电阻率、损耗或机械特性没有实际影响。高于3.0wt%的Mn,将形成例如MnS的硫化物并且可以对磁芯损耗造成不利影响。因此,Mn为使得0.1wt%≤Mn≤3.0wt%,在优选的实施方案中,0.1wt%≤Mn≤1.0wt%。
正如碳,氮可以是有害的,由于氮能够导致AIN或TiN析出,这能够使磁特性劣化。游离氮也能够引起老化,这将使磁特性劣化。因此,氮的浓度应限制为60ppm(0.006wt%)。
锡是本发明的钢的必需元素。锡的含量必须在0.04%与0.2%之间,且两个端值均包括在内。锡对磁特性起着有益的作用,特别是通过织构改善。锡有助于减少最终织构中的(111)成分,并且通过这样做其有助于总体上改善磁特性,并且特别是极化/感应。低于0.04wt%的锡,效果可忽略不计,而高于0.2wt%的锡,钢脆性将成为问题。因此,锡为使得0.04wt%≤Sn≤0.2wt%。在优选实施方案中,0.07wt%≤Sn≤0.15wt%。
需要将硫浓度限制为0.005wt%,这是由于S可能会形成例如MnS或TiS的析出物,这将会使磁特性劣化。
磷含量必须低于0.2wt%。P增加电阻率,这降低损耗、并且由于磷是可能对再结晶和织构起作用的偏析元素还可能会改善织构和磁特性。磷还能够增加机械特性。如果浓度高于0.2wt%,则由于钢的脆性增加而将使工业处理变得困难。因此,P为使得P≤0.2wt%,但在优选实施方案中,为了限制偏析问题,P≤0.05wt%。
钛是可能会形成对磁特性有害的析出物例如:TiN、TiS、Ti4C2S2、Ti(C,N)和TiC的析出物形成元素。钛的浓度应低于0.01wt%。
余量为铁和不可避免的杂质例如本文下面列出的具有根据本发明的钢中允许的最大含量的杂质:
Nb≤0.005wt%
V≤0.005wt%
Cu≤0.030wt%
Ni≤0.030wt%
Cr≤0.040wt%
B≤0.0005
其他可能的杂质是:As、Pb、Se、Zr、Ca、O、Co、Sb和Zn,其可以以痕量存在。
随后对具有根据本发明的化学组成的铸件进行再加热,板坯再加热温度(SRT)介于1050℃与1250℃之间直到整个板坯的温度均匀为止。低于1050℃,轧制变得困难,并且轧机上的力将过高。高于1250℃,高硅级别变得非常软并且可能出现一些松弛,从而变得难以处理。
热轧终止温度对最终热轧显微组织起作用,并且热轧终止温度在750℃与950℃之间。当终轧温度(FRT)低于750℃时,再结晶被限制,并且显微组织高度变形。高于950℃将意味着固溶体中更多的杂质,并且可能导致偏析以及磁特性劣化。
经热轧的带的卷取温度(CT)也对最终经热轧的产品起作用;并且其在500℃与750℃之间。在低于500℃的温度下进行卷取将不允许发生足够的回复,同时该冶金步骤对于磁特性是必需的。高于750℃,将会出现厚的氧化层,并且氧化层将会对于例如冷轧和/或酸洗的后续处理步骤造成困难。
经热轧的钢带呈现出具有取向成分为{110}<100>的高斯织构的表面层,所述高斯织构在经热轧的钢带的厚度的15%处测量。高斯织构为带提供了增强的磁通密度,从而降低磁芯损耗,这从下文提供的表2、表4和表6中可以看出。在热轧期间,通过使终轧温度保持高于750摄氏度来促进高斯织构的成核。
热轧带钢带的厚度从1.5mm变化至3mm。通过通常的热轧机难以得到低于1.5mm的厚度。从大于3mm厚的带冷轧至目标冷轧厚度将大大降低卷取步骤之后的生产率,并且还将使最终磁特性劣化。
任选的热带退火(HBA)可以在650℃与950℃之间的温度下进行,该步骤是任选的。其可以是连续退火或分批退火。低于650℃的均热温度,再结晶将是不完全的,并且最终磁特性的改善将被限制。高于950℃的均热温度,再结晶晶粒将变得过大,并且金属将变脆并在随后的工业步骤期间难以处理。均热的持续时间将取决于是连续退火(10秒与60秒之间)还是分批退火(24h与48h之间)。随后,对带(经退的或未经退火的)进行冷轧。在本发明中,冷轧在一个步骤中进行,即不进行中间退火。
酸洗可以在退火步骤之前或之后进行。
最后,经冷轧的钢经历在介于850℃与1150℃之间(优选地,介于900℃与1120℃之间)的温度(FAT)下根据所使用的温度和目标晶粒尺寸而持续10秒与100秒之间的时间的最终退火。低于850℃,再结晶将是不完全的,并且损耗将无法达到其全部潜能。高于1150℃,晶粒尺寸将过大并且感应将劣化。至于均热时间,低于10秒,给予再结晶的时间不足,然而高于100秒,晶粒尺寸将过大,并且将负面影响例如感应水平的最终磁性能。
最终板厚度(FST)在0.14mm与0.67mm之间。
根据本发明生产的最终板的显微组织包含粒径在30μm与200μm之间的铁素体。低于30μm,损耗将会过高,而高于200μm,感应水平将会过低。
至于机械特性,屈服强度将在300MPa与480MPa之间,而极限拉伸强度应在350MPa与600MPa之间。
