摘要
通过对合金抗拉强度、表面硬度以及冲击韧性等力学性能的测定,分析了矿用机械中锰耐磨钢材料合金元素的不同配比对其力学性能的影响。通过滑动磨损、磨料磨损以及冲击磨损等实验分析了C、Mn元素含量对刮板输送机中锰耐磨钢性能的影响。研究结果表明:新型高耐磨钢材基体的金相组织均为奥氏体组织,晶粒呈不规则多边形;随着Mn元素含量提高,合金钢材的抗拉强度提高、初始硬度降低;随着C元素含量提高,有助于提高材料的初始硬度和耐磨性能;设计的新型高耐磨钢材的Mn元素含量合理范围为7.0%~8.0%,C元素含量合理范围为1.1%~1.2%。
By measuring the tensile strength, surface hardness and impact toughness of the alloy, the influence of different alloy elements ratio on the mechanical properties of manganese wear-resistant steel in mining machinery was analyzed. Through the experiments of sliding wear, abrasive wear and impact wear, the influence of C element and Mn element content on the properties of manganese wearresistant steel in scraper conveyor was analyzed. The results show that the metallographic structure of the new high wear-resistant steel matrix is austenite, and the grain is irregular polygon;with the increase of Mn content, the tensile strength of the alloy steel increases and the initial hardness decreases;with the increase of C content, the initial hardness and wear resistance of the material are improved;the reasonable range of Mn content of the new high wear-resistant steel is 7.0%~8.0%, and the reasonable range of C content is 1.1%~1.2%.
