What are the advantages of pick
2022/08/26
The pick is the direct cutting tool of the shearer and the roadheader. The working conditions are very bad. During the use process, it is subjected to friction and impact from the coal seam or rock. Generally, the working life is relatively short. The main failure mode is because the pick head The tooth body wears too fast, causing the alloy head to fall off or the tooth body has poor bending resistance and is bent or broken under the action of strong force. In view of these situations, let's take a look at the advantages of the pick?
1. The wear resistance of the pick is significantly improved. The advanced plasma cladding strengthening technology is used to clad a hard metal ceramic layer on the head of the pick. The metal ceramic layer has the characteristics of high hardness, good toughness, wear resistance and impact resistance. , It protects the head of the pick tooth body well, reduces the wear speed of the tooth body of the head, makes the tooth body and the alloy head wear synchronously, and achieves a good match.
2. The bending resistance is significantly improved. According to the fracture position and bending condition of the pick during use. The advanced analysis software ANSYS is used to carry out the computer simulation analysis of the force failure of the pick, and according to the analysis results, a unique heat treatment process and other production and processing processes are developed. The overall bending resistance of the tooth body and the surface strength of the tooth shank are greatly improved, which ensures the normal use of the pick.
3. "No sparks" during use. Ordinary picks will generate a lot of sparks during use, especially during rock cutting, which brings great safety hazards to coal mine production. The produced plasma is clad with a high-hardness metal ceramic layer, which reduces the amount of sparks generated by the pick by more than 90% during use, which greatly improves the safety of coal mining.
