What are the emerging technologies for remanufacturing bucket teeth
The following are the emerging technologies and their core breakthrough points in the field of bucket tooth remanufacturing:
I. Precision laser repair technology
Laser cladding shaft wire feeding
High-energy laser beams are used to melt metal wire materials, forming a metallurgical bonding layer on the surface of the bucket teeth. This enables precise repair of high-wear areas such as the tooth root and tooth tip. The hardness of the cladding layer can reach HRC55-62, and the fatigue resistance is increased by more than 30%.
Advantages: Small heat-affected zone (≤1mm), low dilution rate (< 5%), and avoidance of substrate deformation.
Composite strengthening process
For the impact zone of the tooth tip, a dual process of "surfacing + laser cladding of tungsten carbide" is adopted: first, surfacing is used to restore the size, and then tungsten carbide is cladding to enhance wear resistance and extend the service life by more than twice.
2. On-site rapid repair technology
Portable non-disassembly repair
By using mobile laser equipment to carry out on-site operations on the tower or in the factory area, the crack repair of large equipment bucket teeth was completed within 48 hours, reducing downtime losses (saving over 20,000 yuan in a single day).
Supporting technologies: The flaw detector precisely locates the damage, and the hydraulic fixture dynamically calibrates the installation accuracy (error ±0.05mm).
⚙️ III. Material upgrading and technological innovation
Forged bucket tooth steel replaces casting
Specialized forging steel grades such as XXDC and F-23 have been developed. Through composition optimization and controlled cooling process, the casting shrinkage cavity defect has been solved, and the hardness and toughness have been comprehensively improved by 20%.
High-speed oxygen fuel spraying (HVOF)
Tungsten carbide particles are accelerated to 500m/s for spraying, with a porosity of less than 1% and a bonding strength of more than 80MPa. It is suitable for the evolution technology of tooth surface furrow wear repair.
IV. Technical and economic comparison
Technology cost savings repair cycle applicable scenarios
The laser cladding shaft wire feeding cost is 50% lower than that of new parts within 24 to 48 hours, resulting in tooth root cracks and local wear
On-site non-disassembly repair saves 30% without disassembly for emergency maintenance of large equipment within no more than 2 days
Remanufacturing of high-end bucket teeth in batches on a production line for long-life reengineering of forged steel matrix to reduce maintenance costs
Note: Industry trends in 2025 show that precision laser repair and on-site rapid response technologies have occupied 60% of the remanufacturing market share, becoming the core paths for cost reduction and efficiency improvement.
