首先介绍了滚压破岩钻齿磨损机理,根据磨损机理分析了新型烧结复合钻齿的各种影响因素,最后介绍了新型复合钻齿的实际使用情况。新型复合钻齿结合了合金钻齿基体高强度、高韧性和人造金刚石涂层的高硬度、高耐磨性的优点,提高了钻齿的耐磨性而不降低基体的韧性,使钻齿寿命提高了将近96%,为新型复合钻齿在滚压破岩领域尤其是在硬岩极硬岩上滚压破岩应用提供参考,同时也为竖井掘进机的刀具选择提供参考。
Firstly, the wear mechanism of rolling and breaking rock drilling is introduced. According to the wear mechanism, various influencing factors of the new sintered composite drilling tooth are analyzed. Finally, the actual usage of the new composite drilling tooth is introduced. The new composite drilling tooth combines the advantages of high strength, high toughness and high hardness and high wear resistance of the alloy drilling tooth base, improves the wear resistance of the drilling tooth without reducing the toughness of the base, and makes the drilling tooth life Which is nearly 96%. It provides a reference for the application of the new composite drilling teeth in roll breaking rock breaking, especially on the hard rock rock breaking and rock breaking, and also provides reference for the tool selection of the shaft boring machine.
