Abstract
The advantages of dry drilling bit are introduced, as well as the status of domestic dry drilling market, and the principle of the bit matrix design.Ultra-fine tungsten copper alloy powder helps to solve the problems of sintering and drilling in experiment.Tungsten copper alloy powder (mass fraction 45%), with metal powder(Cu, Co, Ni, etc.), is used to make experimental bit matrix through the process of granulation, pre-compression, dewaxing, sintering, and welding.Results show that when sintered at 850 °C, and 25 MPa for 180 s, the hardness of bit segment is more than HRB110, and the effect of diamond grit protrusion is good.Compared with the drilling bit imported from Korean, the granite drilling efficiency of domestic bit is increased by 7%, while the life is equal with Korean drilling bit, which reflects the good performance of dry drilling.关键词
