High-wear-resistance excavator bucket tooth and casting method thereof
The invention discloses a high-wear-resistance excavator bucket tooth and a casting method thereof, and belongs to the technical field of metal materials. The excavator bucket tooth comprises the element components including, by mass percent, 0.24-0.27% of carbon, 0.6-1.0% of silicon, 0.9-1.2% of manganese, 1.0-1.5% of chromium, 0.1-0.2% of tungsten and the balance iron and inevitable impurities.According to the excavator bucket tooth, the tungsten element for grain refinement is added in the casting process, the mechanical performance of the high-wear-resistance excavator bucket tooth is improved, especially, the hardness and impact toughness values are improved, and the bucket tooth is good in wear resistance and long in service life.
本发明公开了高耐磨挖掘机斗齿及其铸造方法，属于金属材料技术领域，所述挖掘机斗齿中各元素成分的质量百分比为：碳0.24‑0.27％，硅0.6‑1.0％，锰0.9‑1.2％，铬1.0‑1.5％，钨0.1‑0.2％，余量为铁及不可避免的杂质。本发明的挖掘机斗齿在铸造过程中添加了细化晶粒的钨元素，提高了高耐磨挖掘机斗齿机械性能，尤其是提高了硬度及冲击韧度值，使斗齿的耐磨性好，使用寿命长。
