2026-01-28
As a critical conductive component in electrolytic aluminum production, the cleaning technology for steel claws is continuously advancing toward higher efficiency and lower energy consumption. The combined application of chain‑swinging cleaning and shot‑blasting has emerged as an important approach to enhancing cleaning efficiency while reducing energy use.
As a critical conductive component in electrolytic aluminum production, the cleaning technology for steel claws is steadily advancing toward higher efficiency and lower energy consumption. The combined application of chain‑swinging cleaning and shot‑blasting has emerged as an important approach to enhancing cleaning efficiency while reducing energy use.
Chain‑flinging cleaning works by rotating a chain to impact the surface of steel claws, using mechanical shock to remove electrolyte residues and other contaminants. Its key advantages include a simple equipment design, low maintenance costs, and a wear‑resistant, low‑consumption chain that delivers outstanding results in removing soft electrolyte deposits. For example, after adopting a chain‑flinging cleaner, one enterprise achieved a processing capacity of 120 parts per hour per unit, increased the pass rate to 98.5%, and reduced operating costs by approximately 40% compared with conventional methods.
Shot blasting cleans the surface of steel claws by propelling abrasive media—such as steel shot—at high velocity, performing a combined grinding action that removes scale and rust while inducing compressive stresses to enhance surface hardness and fatigue strength. The process achieves cleaning speeds of up to 15 m/min, with surface roughness consistently maintained at Ra 0.35–0.45 μm, meeting stringent precision requirements. Meanwhile, a closed‑loop waste recovery system coupled with baghouse dust collection enables 95% abrasive recycling, and dust emission concentrations remain below 20 mg/m³, delivering outstanding environmental performance.
When used in tandem, chain‑shot blasting rapidly removes large debris from the surface of steel claws, providing a preparatory base for shot blasting; in turn, shot blasting delivers more refined surface treatment, further enhancing surface quality. This combined approach not only shortens the processing time per part but also reduces overall energy consumption, offering robust technical support for energy conservation and efficiency improvements in the electrolytic aluminum industry.
