Description

一种矿用钻头
技术领域
    本发明涉及一种机加工用钻头，特别涉及一种矿用钻头。
背景技术
随着社会的进步和经济的快速发展，制造业越来越成为经济的支柱，在制造业中钻头的应用越来越广泛，然而传统的钻头在加工的过程当中，容易磨损甚至断裂，严重影响生产效率以及造成巨大的经济浪费。尤其在矿山作业时，由于其环境恶劣，容易腐蚀以及磨损，一般市售的钻头很容易磨损以及腐蚀，且寿命低下，对企业造成很大的影响。
发明内容
本发明目的是提供一种抗磨蚀强，强度高的矿用钻头。
为达到上述目的，本发明采用的方法是：一种矿用钻头，所述的钻头由以下成分组成：
C 0.12%-0.30%， Mn 3.30%-4.2%，Ti 0.03-0.08% Zr 0.05%-0.22%, Cr 1.7%-2.5% ，Ni 0.35%-1.20% ，V 0.02-0.03% ， Mo 0.5%-2.5% ，B 2.5%-3.3% ，N 0.003-0.01，P <0.022 ，S <0.028，Al 10.28%-11.25%，其余为Fe。
作为本发明的一种优选，所述的各成分比具体为：
C 0.18%-0.25%， Mn 3.80%-4.0%，Ti 0.05-0.07% ，Zr 0.09%-0.12%, Cr 1.9%-2.2% ，Ni 0.65%-1.05% ，V 0.025-0.03% ， Mo 0.95%-1.25% ，B 2.5%-3.3% ，N 0.003-0.01，P <0.020 ，S <0.018，Al 10.58%-10.85%，其余为Fe。
有益效果：
本发明针对现有矿用钻头的不足，在低碳高速钢基础上，加入硼元素，在保持高速钢具有良好高温红硬性的前提下，还具有优异的抗腐蚀能力，能够有效地适应矿上的环境，提高了使用寿命。另外，本发明加入了各种的金属元素，能够改善夹杂物形态和分布的作用，有利于提高钻头的的机械性能，特别是钻头的强韧性和耐腐蚀性，使得钻头更能够适应矿井下的环境。
