Roadheader pick

Roadheader pick repair

Products description：

The pick is a key part for directly cutting coal and rock on the road header. It is a vulnerable part, and its failure mode is mainly wearing failure. The main form of wear failure is the wear of the base body of the pick end, which leads to the peeling of the alloy head. The domestic ordinary picks have a short life and poor wear resistance, which increases the difficulty of underground operations and reduces production efficiency. Laser cladding can improve the wear resistance of the pick end and prolong the service life.

WILA Laser specializes in metal material laser surface treatment, laser cladding remanufacturing, laser strengthening, laser special processing, and other businesses. It can solve the abrasion, corrosion, scratch, scratch, and super processing of flat, cylindrical, and special-shaped mechanical components. And provide reinforcement or remanufacturing solutions. The laser cladding remanufacturing technology used uses a laser as the heat source and uses different filler methods to place the selected coating material on the substrate of the cladding object, and then melt it with a thin layer on the surface of the substrate by laser irradiation. , And quickly solidify to form a surface coating with extremely low dilution and metallurgical bonding with the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical characteristics of the substrate material surface.

The laser cladding remanufacturing technology is not limited by the repair thickness and the number of repairs. Laser cladding remanufacturing technology-the use of high-performance alloy powder to laser strengthen the pick, which greatly improves the wear and corrosion resistance of the pick, and the service life is 1-2 times longer than that of the traditional process, and laser cladding The process coating is well combined with the substrate, so that the laser-strengthened area can fully protect the cemented carbide head, which greatly improves the service performance of the pick.

After cladding

Laser cladding technology can reduce pick replacement time, improve production efficiency, and save a lot of money at the same time. It is an inevitable choice to achieve sustainable economic development. At present, it has been widely used in the engineering manufacturing of coal, steel, petrochemical, electric power, aviation, engineering, railway, and large-scale special equipment industries and the strengthened remanufacturing of key components of important equipment, achieving "green environmental protection, material, and energy-saving, and extended The effect of "lifespan" helps enterprises to innovate in green manufacturing.
