Rotary drilling rig pick consists of which parts
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.

The reason why the pick is very easy to wear
The pick is generally in direct contact with the mined material, so the pick is very easy to wear. Many people think that the quality of the pick they buy is not good and cannot be used for a long time to improve the efficiency of mining. But for the reasons for the wear of the cutting teeth and do not understand why the cutting teeth cause wear. 1. We should know that the use of raw materials will directly determine the quality of the pick. The use of inferior materials and high-quality materials to make cutting teeth, the final production of cutting teeth quality must be different. Even with advanced production technology, it is difficult to achieve a uniform level. Our picks are made of high-quality raw materials, and at the same time, through advanced thermal processing technology, we can manufacture high-quality pick products to ensure their use value, especially after long-term mining of coal seams and mineral seams, there are certain difficulties in mining. 2. The wear of the cutting tooth is not only due to the material itself, but also due to the residual stress of brazing, which makes the cutting tooth unable to withstand the huge impact force and causes the cutting tooth to be damaged. In addition, the pick is also damaged because of red hardness. What is red hardness? Mainly refers to the ability of the pick to maintain high hardness in high temperature environment. When the red hardness is relatively low, the material softens faster, causing the pick to wear too fast. At the same time, when the pick is processed, the heat treatment process is very important, which will affect the stability of its performance. When the heat treatment control is unreasonable, it will cause the wear of the pick.
