Laser Rust Removal Technology for Tank Plates

Principle and Parameters of Laser Rust Removal Technology for Tank Plates:
Employs pulsed fiber laser (1064nm wavelength, 100-300W power) to directly vaporize the rust layer (Fe₂O₃/Fe₃O₄) through photothermal effect, with a single-pass scanning width of 20-50mm and a linear speed of 0.5-2m/min. Compared to traditional sandblasting, energy consumption is reduced by 60% with no secondary pollution, and surface roughness Ra can be controlled within 1.6-3.2μm (GB/T 1031-2025).

Verification of Application Advantages:
Field tests on petrochemical storage tanks in 2025 showed that the risk of hydrogen embrittlement of the substrate after laser treatment was reduced to zero, and the adhesion to the epoxy coating reached 15MPa (ISO 4624), a 40% improvement compared to mechanical rust removal. The intelligent vision system enables AI recognition of rust levels with a positioning accuracy of ±0.1mm.
