技术领域
本发明涉及电磁铁芯钢板技术领域,尤其涉及一种短流程生产高强耐蚀电磁铁芯钢板的方法。
背景技术
电磁铁芯是电磁转换的载体,是电磁铁芯装置的核心组成,常用于电磁控制的开关,也就是电磁铁与开关的结合体。当电磁铁线圈通电后产生电磁吸力,使活动铁芯移动达到开关触点闭合,从而接通所控制电路。电磁开关在各行业有广泛的应用,最常见的是工业领域的接触器和汽车起动机上的控制开关。
生产电磁铁芯用钢板(带)通常可归类于0.50mm~1.3mm厚度的无取向电工钢品种。因其规格的非标准化,并且除效能及电磁响应特性所要求的低损耗、高磁感指标外,更加要求其有别于无取向电工钢产品的高强度、高硬度、耐磨、耐蚀等产品特殊的应用性能。
随着无取向硅钢品种及产品的日益成熟及应用,出于上下游产业更加有利的产品对接,通过产品应用研究及工艺对接,专业且更具个性化的电磁开关专用产品成为上下游合作的重点品种。
目前CN1077500A公开了《一种抗打击高强度硅钢片》,在热轧硅钢片的基础上,通过控制冶炼成分来提高强度,其化学成分wt%:Si:1.50~3.30,C≤0.1,Mn:0.80~2.5;P:0.05~0.15;S≤0.03;CN101745794A公开了《一种高强度专用冷轧无取向电工钢及其生产方法》,利用鞍钢ASP产线,通过成分及工艺控制生产厚度在0.7mm左右的高强度钢;CN101745794A公开了《一种高强耐磨专用冷轧无取向电工钢及其生产方法》,是通过成分控制,无铝钢的情况下提高Si和Mn的含量,同时控制热轧、常化、退火工艺来提高硅钢的强度和硬度。
发明内容
为了克服现有技术的不足,本发明提供了一种短流程生产高强耐蚀电磁铁芯钢板的方法。减少了冷轧轧制工艺,在电磁性能相近情况下,具有表面质量优异、叠装系数高的优点。
为了达到上述目的,本发明采用以下技术方案实现:

铸坯拉出切割后直装隧道式均热炉,入炉温度750℃~1100℃;加热及保温时间皆为20min~60min;出炉温度900℃~1150℃,开轧温度900℃~1100℃,终轧温度800℃~950℃以上,轧制规格0.8mm~1.3mm,卷取温度600℃~850℃。
2)保温或罩式退火;
热轧卷加罩保温或罩式炉保护气氛退火;650℃~850℃保温6h~15h,控制冷却速度20℃/h~150℃/h,200℃以下摘退火罩或出炉冷却至常温。
3)热轧卷酸洗;
4)钢卷平整;控制平整延伸率0.1%~5.0%,控制板形平直度1.0%以下。
所述电磁铁芯钢板按重量百分比计,包括如下组分:
C为0.005%~0.15%,Si为1.3%~2.3%,Mn为0.35%~1.5%,P为0.04%~0.20%,S≤0.035%,Cr为0.05%~1.50%,Cu为0.2%~0.6%,Al为0.1%~1.5%,Sn为0.02%~0.1%,Ni为0%~0.0050%,Nb为0%~0.0050%,Ti为0%~0.0050%,N为0%~0.0050%,V为0%~0.0050%,其余为Fe和不可控残余元素。
与现有方法相比,本发明的有益效果是:
本发明减少了冷轧轧制工艺,生产流程缩短、生产难度及生产成本下降;但是在电磁性能相近情况下,通过本发明所述方法生产的电磁铁芯钢板表面质量优异,强度进一步提升,耐蚀性能提高,加工性优异,铁芯效能提升,叠装系数提高1%以上,锈斑减少80%。
具体实施方式
下面对本发明的具体实施方式作进一步说明,但不用来限制本发明的范围:
一种短流程生产高强耐蚀电磁铁芯钢板的方法,具体包括如下步骤:
1)薄板坯连铸连轧,热轧卷高温卷取;
符合产品冶炼成分钢水,控制过热度0℃~30℃开始浇铸,铸机拉速2.0m/min~6.0m/min,控制板坯轻压下5mm~20mm,浇铸板坯厚度规格为50mm~90mm。
铸坯拉出切割后直装隧道式均热炉,入炉温度750℃~1100℃;加热及保温时间皆为20min~60min;出炉温度900℃~1150℃,开轧温度900℃~1100℃,终轧800℃~950℃以上,轧制规格0.8mm~1.3mm,卷取温度600℃~850℃。
2)保温或罩式退火
所述保温或罩式退火为热轧卷加罩保温或罩式炉保护气氛退火;650℃~850℃保温6h~15h,控制冷却速度20℃/h~150℃/h,200℃以下摘退火罩或出炉冷却至常温。
3)热轧卷酸洗
所述热轧卷酸洗为钢卷常规酸洗。
4)钢卷平整,控制平整延伸率0.1%~5.0%,改进表面质量,控制板形平直度1.0%以下,提高叠装系数;根据用户需求,常规重卷分卷精整包装或产品矫直切板、检验、出厂。
所述电磁铁芯钢板按重量百分比计,包括如下组分:
C为0.005%~0.15%,Si为1.3%~2.3%,Mn为0.35%~1.5%,P为0.04%~0.20%,S≤0.035%,Cr为0.05%~1.50%,Cu为0.2%~0.6%,Al为0.1%~1.5%,Sn为0.02%~0.1%,Ni为0%~0.0050%,Nb为0%~0.0050%,Ti为0%~0.0050%,N为0%~0.0050%,V为0%~0.0050%,其余为Fe和不可控残余元素。

5)Al强化元素,控制析出物影响,改进电磁性能及轧制加工性。
6)Cr强化元素,配合其它元素改进产品耐蚀性;促进C析出,抑制磁时效。
7)Cu近强化元素,控制析出物影响,配合其它元素改进产品耐蚀性。
8)Sn微量添加元素,改进晶界析出物组成及形态,促进有利晶体结构生产,改善轧制性能。
9)S及残余Ti、Nb、V、Ni、N元素:有害元素,冶炼控制及整体工艺控制有害化影响。
