Description
技术领域
本发明涉及焊接材料领域,特别涉及一种耐磨堆焊焊条及其制备方法。
背景技术
目前,国内钢铁行业使用的烧结机根据其使用情况、失效情况,特别是高温部件进行相应的修复以及复合制造,已经可以达到满意的效果。特别是烧结机单齿辊、锤头、下料衬板、磨煤辊、冲击板等均需要进行刨削、堆焊并加工成相应尺寸再进行使用,是目前最为常见且经济的修复方法。在堆焊时,大多采用全位置焊接性能好的堆焊焊条。然而这种堆焊方式存在以下问题:1.堆焊工艺性能不稳定。2.高温性能不稳定,硬度不均匀。3.耐磨性不好。以上问题均制约着该类高温性能要求较高的耐磨堆焊焊条的发展。
通过对高温耐磨性能的研究,使得研发的堆焊焊条具有良好的工艺性能,优良的高温耐磨性能,能满足钢铁行业对相关部件高温性能的要求,达到国内先进水平,是焊接行业的技术追求。
发明内容
本发明的目的之一就在于提供一种用耐磨堆焊焊条,该焊条高温性能优良、焊接工艺性能和理化性能良好的耐磨堆焊焊条,电弧稳定性好,飞溅小,烟尘少,脱渣容易。

本发明的目的之二在于提供一种耐磨堆焊焊条的制备方法。
技术方案是:一种耐磨堆焊焊条的制备方法,包括以下步骤:
①将药皮粉料拌混合均匀;

③采用低碳钢焊芯在油压式焊条生产设备上进行焊条制备。
发明原理:
C:碳用于提高材料的硬度和耐磨性能,本发明中熔敷金属中的碳含量达到了5%,提供了足够的耐磨相组织。
Mn:锰是重要的脱氧剂,同时也是焊缝金属重要的合金剂。对焊缝金属的强度和韧性有重要影响。锰能与硫形成MnS,降低焊缝的杂质含量。Mn能够有效地减少焊缝金属中的含硫量,因此适量的加入可以提高焊缝金属的强度。
Cr:用以提高耐磨性,与碳结合形成稳定的碳化物,均匀的分布在基体中,是提高焊缝金属耐磨性的主要元素。
Si:用以降低焊缝中氧的含量,并提高焊缝的硬度。
Ni:用以提高焊缝的韧性,改善熔敷金属的开裂倾向。
Ti;用以细化晶粒,改善组织大小,提高熔敷金属的综合性能减小裂纹倾向。
W:用以强烈提高熔敷金属的硬度,增强高温耐磨性能。
B:微量加入,能大幅提高熔敷金属的淬透性。
有益效果:
本发明焊条工艺性能好,耐高温性能优良,最高工作温度可达600℃-1000℃,适应性强,能适应用户对焊接工艺及操作性能的要求。本发明解决了高温耐磨性能差的问题,硬度达到HRC58以上,高温耐磨性能非常好。
