Power Industry

The current petrochemical industry adopts the mode of large-scale continuous production. Due to the long-term operation and harsh environment of the equipment, the products are prone to corrosion and wear, which will lead to the loss of the working ability of large parts, such as impellers, journals, wheel discs, shaft sleeves, bearing bushes, etc. However, the price of these parts is often very expensive, involving many types of parts and complex shapes, and have great differences in working conditions. To ensure normal production, chemical equipment with reliability, safety, and integrity should be used. Laser cladding technology can meet the needs.

Large rotor and shaft parts are repaired by laser cladding technology. The size of the journal can be restored without preheating the workpiece, the amount of subsequent processing is small, not easy to produce metallurgical cracks, the hardness can reach HR60 or more, and the strength of the repaired parts can reach more than 90% of the original strength. Best of all, the repair cost is less than 1/5 of the replacement price. More importantly, it shortens the maintenance time and solves the problems that must be solved in the continuous operation of major complete sets of equipment in the petrochemical industry. In addition, the cladding of super wear-resistant and corrosion-resistant alloy on the surface of key parts can greatly increase the service life without deformation of the part surface.
