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.
