During the construction of the coal mining cutting face, the pick needs to bear huge compressive stress and impact load, so the alloy head and wear-resistant layer of the pick will be worn. The pick needs to be replaced after wear and tear. Installing a new pick to continue working is a consumable. Therefore, the pick has become one of the most widely used coal mining machinery parts. So how can we do a good job of strengthening the wear resistance of the pick?

       Usually, pick manufacturers can use thermal spraying, plasma cladding, laser cladding, surfacing welding, and plasma beam surface metallurgy.

       The heat treatment by brazing method is also one of the key technologies to ensure the quality of the pick. Now the brazing and heat treatment of the pick can be said to be integrated. It is actually heated by a vacuum furnace, so that the brazed pick can be directly processed without air cooling. Quenching, brazing and heat treatment are completed at one time.

       Wuxi Semax picks are upgraded with alloy composite coating. The technology used is the self-developed inlay deep melting process, which makes the wear resistance of the picks 1.5-2 times, especially in the ultra-hard rock working conditions. outstanding performance.

       We need to do a good job in the reliability of the pick, improve its reliability well, and reduce the proportion of coal pick consumption in the coal cost, so as to effectively improve the effective working time of the coal machine and strengthen the strengthening technology of the coal pick. It can also improve the performance of the coal pick very well.
