Description
技术领域
本发明涉及耐磨材料领域,具体涉及一种低铬耐磨球的热处理工艺。
背景技术
球磨机是工业生产中广泛使用的高细磨机械之一。耐磨球是球磨机的粉碎介质,通过耐磨球之间、耐磨球与物料之间的碰撞摩擦产生磨削作用,从而将物料的粒径进一步减小。现有技术中,耐磨球主要是铬系合金、锰系合金等球磨铸钢件或球磨铸铁件,如高铬钢球、低铬钢球、多元合金钢球和钒钛铬合金钢球等,其工作对象多为水泥、煤炭、矿石、煤渣等。磨煤机钢球在使用时球的硬度和耐磨性是影响磨煤机整形效果的主要因素之一。为了提高破碎效率和钢球的耐用度,需要钢球表面有足够的硬度和耐磨度。同时,在研磨过程中,钢球与磨料、钢球与衬板以及钢球与钢球之间发生的冲撞不可避免,因此,还要求钢球有一定的韧性,避免破球,另外,水泥、煤炭、矿石、煤渣中还含有大量腐蚀性物质,会对耐磨球造成腐蚀,这就要求耐磨球具有一定的耐腐蚀性,这些都对耐磨球的综合性能提出了更高的要求。
发明内容
(一)解决的技术问题
针对现有技术的不足,本发明提供了一种低铬耐磨球的热处理工艺,具有工艺简单,成本低,生产出的耐磨球强度和硬度高、韧性大、耐热耐腐蚀性好的优点。
(二)技术方案
为实现以上目的,本发明通过以下技术方案予以实现:
一种低铬耐磨球的热处理工艺,包括以下步骤:
(1)用丙酮对耐磨球表面进行超声波清洗,砂纸打磨、超声波水洗和干燥待用,将合金切割成所需的尺寸;
(2)将耐磨球和合金放入双辉等离子表面冶金渗金属炉内,将耐磨球作为工件极,将合金作为源极,将双辉等离子表面冶金渗金属炉抽真空至气压为0.5-1.5Pa,向炉腔内通入氩气和氮气的混合气体,混合气体的气压为20-30Pa,启动辉光,控制源极电压为800-950V,工件电压为500-600V,工作时间为3-5h;
(3)关闭辉光,将耐磨球取出,放入加热设备中,先升温至200-300℃,保温10-15min,再升温至800-980℃,保温2-3h后放入浓度为15-25%的水基淬火剂中淬火,将耐磨球从水基淬火剂中取出后静置10-20min后,再放入加热设备中加热至400-500℃,保温1.5-3h后空冷出炉,即可得到耐磨球成品。
优选地,所述耐磨球由以下质量分数的元素组成:C 1.13-2.42%、Si 1.15-1.80%、Cr 0.44-1.35%、Mn 1.13-1.55%、Ni 0.23-0.45%、V 0.24-0.40%、P≤0.015%、S≤0.015%,其余为铁和其他不可避免的杂质。
优选地,所述合金由以下质量分数的元素组成:Cr 22.3-28.1%、Al 17.5-22.4%、Ni 10.8-16.7%、Co 9.3-15.4%、Ti 1.26-1.55%、W 0.12-0.20%、Mo 0.23-0.45%、其余为Fe。
优选地,所述混合气体中氩气和氮气的体积比为1:3.
优选地,所述水基淬火剂为THIF-501水基淬火剂或THIF-502水基淬火剂。
优选地,所述合金渗层的厚度为250-400μm。
(三)有益效果
本发明提供了一种低铬耐磨球的热处理工艺,具有以下有益效果:
(1)通过添加Mo、V、Co等元素或是增加Cr和Ni等元素的含量可以提升耐磨球的强度和硬度,但是这些元素往往价格昂贵,这会大大增加成本压力,相比较而言,通过改进热处理工艺和进行渗透处理,既可以提升耐磨球的综合性能,所用到的成本会小的很多,本发明工艺简单,适合大规模工业应用,耗能小,成本低。
(2)双辉等离子技术可以在较低的气压和较短的时间内在耐磨球表面形成有效金属渗层,而且会有部分氮元素进入渗层中,有效提升耐磨球的强度、硬度和耐热耐腐蚀性能,使用寿命大大增加。
(3)热处理工艺可以提升金属渗层的致密性,改善金属渗层和耐磨球的晶相结构,提升其强度和韧性,而且热处理时不使用有机淬火剂更加环保,减少了对环境和操作人员健康的危害。
