Laser enhanced manufacturing and remanufacturing technology can repair the surface of mud pumps, gear shafts, rocker arms, gears, bushes, oil cylinders, guide shoes, and cutting teeth; strengthen the oil cylinders, brackets, bushes, and cutting teeth of boring machine; Laser cladding of stainless steel alloy on the surface of hydraulic cylinder; laser repair of worn parts on the surface of scraper conveyor middle groove, transition groove, gearbox, gear shaft, spiral bevel gear.

The technological innovation of laser additive manufacturing for slurry pumps lies in:

Slurry pump

(1) Through laser additive manufacturing composite material technology and advanced composite material and structural technology, the additive manufacturing repair of scrapped slurry pumps is realized, and the wear resistance performance reaches the wear resistance level of new high-chromium cast steel 60HRC.

(2) The slurry pump adopts ordinary cast iron material to meet the rigidity and strength requirements, and reserves the shape and size of wear-resistant ternary composite material (coating) for additive manufacturing to form a new type of slag that is coated with wear-resistant ternary composite material and ordinary cast iron. Slurry pump, and reach the wear resistance level of traditional high chromium cast steel 60HRC, can be repeatedly prepared, realize recycling, energy saving and environmental protection in the whole process.

The column of hydraulic support is the key equipment of coal mine machinery. It has been working in acid and alkaline corrosive medium for a long time, and the surface of the column is subjected to corrosion, wear and impact. Using the ultra-high-speed laser cladding technology developed and researched by our company for repair can better improve the wear resistance and corrosion resistance of the column and increase the service life.
