摘要
针对装载机铲斗主切削刃不耐磨问题,分析其组织性能、磨损方式和工况适应性。通过替换新耐磨材料以及优化热处理工艺,提高其淬透性及晶粒度,从而提高了心部硬度以及冲击韧性。工况试验对比表明,新材料在沙石工况和锰矿工况刀板的使用寿命分别提升了60%和87%。
Aiming at the problem that the main blade of loader bucket is not wear-resistant,its microstructure,wear mode and working condition adaptability are analyzed.By replacing the new wear-resistant material and optimizing the heat treatment process,the hardenability and grain size were improved,thus the core hardness and impact toughness were improved.The service life of the new material is increased by 60%and 87%respectively in sandstone condition and manganese ore condition.
