Forging Mill Scale

Forging scale contamination, it arises from thermal damage in metal processing. This contamination forms unique patterns, like layered oxide buildup on steel surfaces and thus adheres strongly during high-heat forging. Material behaviors differ; steel shows thick, irregular scales from rapid oxidation, while aluminum develops thinner, porous ones and resists cracking less. Removal challenges emerge, especially with laser cleaning. Scale resists ablation due to its dense structure, so pulses must target precisely to avoid substrate damage. After treatment, surface smoothness improves, yet remnants persist on irregular areas. This contamination, it demands adjusted laser parameters for effective detachment and thus enhances cleaning efficiency on varied metals.
