Description
技术领域
本发明涉及一种金属材料，尤其涉及一种煤截齿。
背景技术
截齿是煤炭行业中采煤机、掘进机、刨煤机等采煤装置上用来破岩落煤、截割煤岩、碎煤用的刀具。截齿通常安装固定在截齿座上，采煤装置的旋转机构带动截齿一并旋转，旋转的截齿直接截割煤岩，将煤岩切割打碎成小块后，通过运输装置向矿外运出煤炭。由于截齿在破碎煤矿中会反复直接受到煤矿的冲击和摩擦，磨损严重，使用寿命往往较短，需要经常更换磨损的截齿，而通常采煤装置的旋转机构上配置有较多截齿，所以每次更换截齿均需花费太多时间，影响了采煤装置的工作效率，增加了煤炭的生产成本。
发明内容
为了克服现有技术的不足，本发明提供了一种耐磨煤截齿，该截齿强度、硬度耐磨性、耐蚀性大大提高，使用寿命更长，可减少更换次数，降低采煤成本。
为解决上述技术问题，本发明所采用的技术方案是：
一种耐磨煤截齿，包括齿头和齿柄，齿头和齿柄一体成型，齿头包括齿头本体，齿头本体上堆焊有合金材料层，其特征在于：所述合金材料层包括如下以重量百分比计的成分：
碳0.8～1.2%
钴0.6～0.72%
钨0.06～0.12%
钛0.2～0.45%
钒0.1～0.15%
铬0.8～1.35%
钽0.08～0.15%
硼5.8～6.2%
镍6.5～6.82%
余量为铁和不可避免的杂质。
所述合金材料层包括如下以重量百分比计的成分：
碳0.86%
钴0.65%
钨0.085%
钛0.36%
钒0.12%
铬1.2%
钽0.13%
硼5.92%
镍6.63%
余量为铁和不可避免的杂质。
本发明具有以下有益效果：
本发明中的钛可以起到细化硬质合金的铸造组织和焊缝组织的作用；钒可以提到金属材料的硬度，铬可以提高金属材料的强度、硬度和耐磨性；镍能够起到耐热、防腐的作用；钴能够提高合金材料的耐热性和防腐性和硬度，钨能提高材料的硬度和耐蚀性，钽能够提高合金材料的耐蚀性。
本发明提供的硬质合金截齿中各元素相互配合、协同发挥作用，具有优异的机械性能、耐磨性、耐蚀性、耐热性，其硬度和强度完全能够达到截齿的要求，并且具有优异的韧性、刚度和耐磨性，另外所述金属材料质地紧密，品质高。
本发明提供的一种硬质合金截齿，耐磨性好，硬度高，磨损速率低，而且其能够有效抵抗煤炭的冲击，不易脆断。基于以上优点，该硬质合金截齿的使用寿命长，相应的维护周期也较长，避免频繁更换硬质合金截齿而停机，影响煤炭的正常生产。
