Establishing a proper maintenance schedule for high-temperature dross skim blades is essential for optimizing casthouse operations in primary and secondary aluminum plants. These skimming tools, which operate in extreme thermal environments typically ranging from 600 to 700 degrees Celsius, require systematic attention to ensure consistent performance and extended service life. A well-structured maintenance approach addresses the unique challenges posed by thermal shock and material degradation while maximizing the efficiency of aluminum dross removal operations. Understanding Operational Demands on Skimming Blades Aluminum skimming equipment faces intense operational stresses during routine dross removal from reverberatory furnaces. The skimming blade encounters rapid temperature fluctuations as it repeatedly enters and exits the molten aluminum surface, creating thermal shock conditions that can compromise structural integrity over time. In North American and European aluminum facil
