Cutting Pick Plasma Hardfacing Machine

Cutting pick plasma hardfacing machine is used to coat the end of the cutting pick of the coal miner with an alloy wear layer, and the final thickness of the wear layer is 1.5~2mm. The average microhardness of the pick tooth is HV800. Rockwell hardness is HRC65, which significantly improves the wear resistance of the pick tooth layer of the coal miner. Wear performance, significantly improving the life of the picker. A comparison with other methods of obtaining a pick block wear layer shows that the use of plasma welding to repair coal miner pickets is worth promoting. The application prospect is promising.

The plasma beam coating technology is used to uniformly cover the thickness of the metal alloy layer in the head of the cutter. Which effectively protects the carbide tip and improves the wear resistance of the head of the cutter. Thus substantially extending the service life of the cutter. And at the same time, the coating layer “does not produce sparks.”. When cutting rocks or encountering coal nodules, it improves the safety performance of coal production and solves a long-standing problem plaguing coal production safety.
