挖掘机斗齿直接与矿石和土壤接触,工作条件恶劣,除正常磨损外,还承受强烈的冲击负荷。影响斗齿使用寿命的因素很多,除矿石结构、爆破情况及使用的合理性之外,斗齿材料与热处理工艺是不可忽视的重要因素。本文就4m~3挖掘机所用斗齿在国内一些矿山的使用情况作了简单介绍,并对今后斗齿的生产提出一些看法。
The teeth of the excavator are in direct contact with the ore and soil, and the working conditions are poor. In addition to normal wear, the excavator bears a strong impact load. There are many factors that affect the service life of bucket teeth. In addition to ore structure, blasting conditions and rationality of use, bucket tooth materials and heat treatment processes are important factors that cannot be ignored. This article gives a brief introduction to the use of bucket teeth used by 4m~3 excavators in some domestic mines, and puts forward some opinions on the production of bucket teeth in the future.
