Small loose

In the process of working, the pick needs to bear huge compressive stress, as well as shear force and impact load, so it is easy to wear and tear, and therefore, it has become one of the coal mine machinery parts with a large amount of replacement. Do a good job of strengthening the pick.

There are some ways to deal with this problem. For example, thermal spraying can be used, plasma cladding can be used, laser cladding can be used, surfacing welding can be used, and plasma beam surface metallurgy can be used.

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

We must do a good job of the reliability of the pick, improve its reliability, and reduce the proportion of coal pick loss in the coal cost, so as to effectively improve the effective working time of the coal machine. Strengthening the strengthening technology of coal picks can also improve the performance of coal picks.
