Custom Laser cladding equipment for hydraulic rod Supplier, Suppliers
Laser cladding technology applied to hydraulic support is a new surface modification technology in recent years, mainly for the hydraulic support column and piston rod surface surface reinforcement treatment. The application of laser cladding technology in hydraulic support column repair is described below.The working principle of laser cladding technology is, using high energy laser beam as a heat source, will have high hardness, good anticorrosion function of alloy powder, hydraulic support column and jack surface at the same time melting metallurgical reaction and has the function of wear resistance of laser cladding layer, so as to achieve the purpose of hydraulic support service life, compared with the traditional electroplating process, laser cladding technology has significant technical advantages.
Laser cladding has the typical characteristics of low heat transport, and can meet the requirements of strength, wear resistance and corrosion resistance according to the damage form and degree of the hydraulic support column. Because the properties and ratio of cladding materials have a great impact on the laser cladding effect, the appropriate binder and cladding elements should be preferred to ensure the good secondary protection effect after the fine repair of the smooth weld grains.
Laser cladding technology applied in coal mine hydraulic support is a new surface modification technology in recent years, mainly to strengthen the hydraulic support column and the outer surface of the piston rod. The working principle of this technology is that the use of high energy laser beam as a heat source, will have high hardness, good corrosion function of alloy powder, hydraulic support column and jack surface at the same time melting metallurgical reaction and form has the function of wear resistance of laser cladding layer, so as to achieve the purpose of hydraulic support service life.
Compared with the traditional electroplating process, laser cladding technology has significant technical advantages. High-speed laser cladding metal powder is made of iron-based alloy powder. Take the 6000W high-speed laser cladding equipment with a large market share as an example:
Efficiency & Quality
Dilution rate is less than 3%; cladding thickness of 0.6mm meets requirements; high powder utilization (70% coaxial, 90% central).
Surface Properties
Surface roughness about Ra10um, hardness greater than HRC55, with significantly improved wear resistance.
Durability
Metallurgical combination with substrate; shear strength > 500Mpa; high microhardness and strong corrosion resistance.
Above is the application of laser cladding technology in the hydraulic support column repair. Laser cladding and inner wall cladding technology, with its own technical advantages, combined with substrate metallurgy, high surface treatment efficiency, outstanding economic benefits, and green pollution-free advantages, is the inevitable choice of hydraulic support surface treatment technology development.
