Description
技术领域
本发明涉及不锈钢加热片技术领域,尤其涉及一种不锈钢加热片及其制备方法。
背景技术
不锈钢是不锈耐酸钢的简称,耐空气、蒸汽、水等弱腐蚀介质或具有不锈性的钢种称为不锈钢;而将耐化学腐蚀介质(酸、碱、盐等化学浸蚀)腐蚀的钢种称为耐酸钢。
由于两者在化学成分上的差异而使他们的耐蚀性不同,普通不锈钢一般不耐化学介质腐蚀,而耐酸钢则一般均具有不锈性。"不锈钢"一词不仅仅是单纯指一种不锈钢,而是表示一百多种工业不锈钢,所开发的每种不锈钢都在其特定的应用领域具有良好的性能。成功的关键首先是要弄清用途,然后再确定正确的钢种。和建筑构造应用领域有关的钢种通常只有六种。它们都含有17~22%的铬,较好的钢种还含有镍。添加钼可进一步改善大气腐蚀性,特别是耐含氯化物大气的腐蚀。
不锈钢指耐空气、蒸汽、水等弱腐蚀介质和酸、碱、盐等化学浸蚀性介质腐蚀的钢,又称不锈耐酸钢。实际应用中,常将耐弱腐蚀介质腐蚀的钢称为不锈钢,而将耐化学介质腐蚀的钢称为耐酸钢。由于两者在化学成分上的差异,前者不一定耐化学介质腐蚀,而后者则一般均具有不锈性。不锈钢的耐蚀性取决于钢中所含的合金元素。
其中,不锈钢片在包括地采暖领域在内的多个加热领域(如产品加热、管道伴热、道路融雪、建筑物化冰等)均有应用,然而,现有的不锈钢片存在加热不均、加热慢、耗电大的问题,并且在长期使用后,其自身强度和抗拉能力也发生退化,因此,现有技术还有待改进。
发明内容

进一步的,按重量百分比计:铬Cr:19.5%-20.5%。
本发明的另一个目的在于提供一种不锈钢加热片的制备方法,其方法包括以下步骤:
1)将20Cr-5Al钢和上述重量百分比的硅Si、磷P、锰Mn、铝Al、铬Cr金属溶液倒入至真空感应炉中进行精炼,将金属溶液浇注呈钢锭,将钢锭通过连续铸造、或带材铸造制备成薄带坯料;
2)将薄带坯料的温度加热至1100℃以上,将薄带坯料轧成板状坯料,随后将板状坯料轧至为厚度为1.5mm的带状坯料;
3)将带状坯料放入至连续式退火炉中,退火炉中通入惰性保护气体,在600℃温度下进行退火处理;
4)将退火后的带状坯料通入至酸液槽内进行酸洗处理;
5)用冷轧机将清洗后的带状坯料轧成厚度为1mm的不锈钢薄带;
6)通过精轧法将不锈钢薄带加工至厚度为30μm;
7)将厚度为30μm的不锈钢薄带切割成预设尺寸的加热片。
进一步的,步骤6)中的冷轧速度为30-60米/分钟。
进一步的,步骤6)之后,还需要对不锈钢薄带的表面进行打磨处理。
进一步的,步骤4)的酸洗槽内选用选用盐酸溶液或硝酸溶液进行酸洗处理。
进一步的,加工后的不锈钢薄带密度为7.181g/cm3。
本发明的有益效果为:本发明通过配方及工艺的改良,通过限制Al、铬Cr在总原材料中所占的重量百分比,有效改善了不锈钢片的材质均匀性、导电性和延展性,且通过精轧法可将加热片加工至30μm的厚度,并保证加工精度,从而解决了现有的不锈钢片存在加热不均、加热慢、耗电大的问题,通过材料配比的限定,极大的延长了不锈钢加热片的使用寿命,延缓了其自身强度和抗拉能力发生退化的进程。
