Description
技术领域
本发明涉及合金材料技术领域,具体为一种轧辊用高速合金钢及其制备方法。
背景技术
不锈钢的耐蚀性随含碳量的增加而降低,因此,大多数不锈钢的含碳量均较低,最大不超过1.2%,有些钢的Wc(含碳量)甚至低于0.03%(如00Cr12)。不锈钢中的主要合金元素是Cr(铬),只有当Cr含量达到一定值时,钢才有耐蚀性。因此,不锈钢一般Cr(铬)含量至少为10.5%。不锈钢中还含有Ni、Ti、Mn、N、Nb、Mo、Si、Cu等元素。申请人根据自己多年的研究发现,上述规律有着一定的科学性,轧辊在合金的选择上要求较高,要求合金具有耐腐蚀性、耐磨性、高硬度等诸多要求,现有的合金在选择的时候经常不符合要求,需要重新做,从而造成返工,浪费时间和财力。
发明内容
为了解决背景技术中所提出的技术问题,本发明提供一种黏稠偶联剂加热喷淋装置,采用的技术方案如下:
一种轧辊用高速合金钢,其由以下成分组成:C:2%-3%;Si:1.0%-1.5%;Mn:0.5%-0.6%;Cr:5%-6%;Mo:2%-3%;Ni:1%-2%;V:0.2%-0.5%;W:0.2%-0.5%;Nb:0.05%-0.2%;Ti:0.15%-0.25%;Al:1%-2%;P:0.05%-0.10%;S:0.05%-0.10%;Cu:0.02%-0.15%;Mg 0.15%-0.20%;Al2O3 1.5%-2.5%;余量为Fe。
一种轧辊用高速合金钢的制备流程包括以下步骤:电炉冶炼,将权利要求1所述的配比的材料加入到冶炼炉中,其中初始C只加入1.5%-3%;Al2O3只加入0.5%-1%;W不加、P不加、S不加;步骤1中的充分冶炼后,再次将余量C、Al2O3、W、P、S混合均匀后一次性加入电炉中进行精炼,此处步骤非常关键,也影响轧辊的性能;将精炼后的钢水倒入模具中铸模,使轧辊成型;对成型后的轧辊进行热处理;修磨成型的轧辊;检查轧辊的性能,修磨后的轧辊满足质量要求,上交产品。
与现有技术相比,本发明具有以下有益效果:
通过本发明的合成工艺,由于C的加入量超过了已知C的加入量,从而使生产成本降低,但在生产成本降低的情况下,生产出的合金的耐腐蚀性能不变,而且通过此工艺生产出的合金在合成的过程中通过检验合金的成份,申请人发现有石墨烯的成分,从而使本工艺生产出的合金的不仅抗拉强度度、屈服强度也高、耐腐蚀性能更强、耐磨性能也更好,能够满足工艺生产的要求。
具体实施方式

申请人将上述实施例的合金钢的力学性能
表一
申请人通过分析对比采用实施例1和实施例三的方法制出的合金钢的性能较好,而且各个部分的指标远超标实际标准数值,能够满足轧辊的制备要求,在制备轧辊时不全再被返工,能够提高生产效率,大大地提高了产品性能的同时,还降低了生产成本,又由于在检测时发现合金中含有一定的石墨烯的成份,整个合金钢的耐磨性能和强度又得到进一步提高。
此外,应当理解,虽然本说明书按照实施方式加以描述,但并非每个实施方式仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经适当组合,形成本领域技术人员可以理解的其他实施方式。
