The grate shaft of a waste incinerator operates in a high-temperature and highly corrosive flue gas environment at over 800°C for extended periods. Traditional heat-resistant steel overlay welding is prone to thermal cracking, while thermal spray coatings oxidize and spall at high temperatures, resulting in a service life of only 3-6 months. Frequent replacements cause significant downtime losses for the incinerator.
Daodao Dao Laser Cladding Equipment utilizes high-temperature corrosion-resistant nickel-based alloy + ceramic composite powder. The cladding layer maintains 90% strength at 900°C, with corrosion resistance 6 times that of traditional surfacing. The equipment employs inert gas for full-process cladding protection, preventing coating oxidation. The bonding strength exceeds 400MPa, free of cracks or defects.
The service life of the repaired grate shaft is extended to 1-1.5 years, which is 3-5 times that of traditional processes. After adopting this technology, a waste-to-energy incineration plant achieved annual maintenance cost savings exceeding 1.2 million yuan, significantly reduced downtime, and perfectly adapted to the stringent operating conditions of environmentally compliant incineration equipment.
