China Aluminum Industry Network – When purchasing raw materials and auxiliary materials, it is essential to source them exclusively from the list of approved suppliers. Each batch must come with a quality assurance certificate or a certificate of conformity. Before being allowed into production, all incoming materials must undergo inspection or verification to ensure they meet the required standards.
It is crucial to carefully calculate ingredient ratios to avoid any miscalculations that could lead to quality issues. During the weighing, transportation, and feeding stages, strict attention must be paid to prevent errors such as incorrect ingredient lists, wrong weights, mislabeled materials, mixing of different substances on-site, or improper feeding procedures.
The smelting process must strictly adhere to established procedures and specifications. Operators should ensure that the temperature of added magnesium remains within the correct range, avoiding both excessively high or low temperatures. The method of adding magnesium must also be correct to prevent burning at the surface of the molten metal. Iron tools should be painted to avoid contamination from iron, which can affect the final product quality.
To prevent excessive smelting times that may result in significant metal loss, operators should monitor the process closely. Proper mixing of the molten aluminum is essential to ensure a uniform composition. Additionally, chemical analysis should be conducted before and after the smelting process to ensure accurate results and prevent the use of incorrect or misleading test reports.
By following these guidelines, the aluminum production process can maintain high-quality standards, reduce waste, and improve overall efficiency.
