Rotary drilling rig pick is one of the vulnerable parts in the operation of rotary drilling rig, is the main tool for drilling hard formation, rotary drilling rig pick is mainly composed of pick head, pick handle, alloy cutter head, often the pick handle and pick head and called pick cutter body. There are many kinds of rotary cutting teeth. The general structure is to insert hard alloy cutter head on the low alloy structural steel cutter body treated by quenching and tempering. During the production process, the material of the cutter body should meet or exceed the required mechanical performance indicators through heat treatment. The main failure forms of the cutting teeth of rotary drilling rig are the falling off of the cutter head, the chipping of the cutter, the wear of the cutter head and the cutter body, and the failure of the cutting teeth is often caused by the breakage of the cutter body under some working conditions. The brazing and heat treatment process of the pick is one of the key technologies to ensure the quality of the pick. At present, cutting tooth brazing and heat treatment are integrated technologies. It is the use of vacuum furnace heating, so that the brazed pick without air cooling direct quenching, brazing, heat treatment once completed. Choose a good pick can effectively improve the efficiency of rotary drilling rig, so as to earn greater profits for users. The choice of poor quality rotary drilling rig pick, it will bring unnecessary economic losses and endless trouble. Carefully understand the relevant knowledge of rotary drilling rig pick, every rotary drilling rig operator must pay attention to things.
