SL型矿用钻头是金属露天矿钻凿矿岩炮孔的重要工具之一。其寿命的高低不仅直接影响着矿岩的穿孔成本,更重要的是影响着冶金、机械、国防等各项事业的发展速度。影响钻头寿命指标的因素很多,在组织形式完善和计划性正确的基础上,其它方面主要有如下五点: 1.钻头结构和主要技术参数; 2.钻头的机械加工工艺和工夹量具及设备的先进性; 3.钻头的热处理工艺和材质; 4.矿岩的物理机械特性; 5.钻头工业性运转的运行制度(如:钻头种类
SL-type mining drill bit is one of the important tools for drilling open-hole blast holes in metal open-pit mines. The level of its life not only directly affects the perforation cost of ore rock, but more importantly, it affects the development speed of various undertakings such as metallurgy, machinery and national defense. There are many factors that affect the life index of drill bit. On the basis of perfect organizational form and planned correctness, other aspects mainly include the following five points: 1. Drill bit structure and main technical parameters; 2. Drill bit machining process and clamp measuring tools and equipment Of the advanced nature; 3. Drill heat treatment process and material; 4. Physical and mechanical properties of ore; 5. Drill industrial operation of the operating system (such as: drill type
