- Introduction
1. Background and significance of the standard
GB/T 1196—2023 is a national standard of the People's Republic of China, with the full name of "Aluminum Ingots for Remelting". This standard was issued in 2023, replacing the old version of the standard (GB/T 1196—2017) in 2017, and is mainly applicable to aluminum ingots for remelting produced by alumina-cryolith molten salt electrolysis.
2. Background of standard formulation
The revision of this standard reflects the progress of technology and quality management in my country's non-ferrous metal industry. Compared with the old version, the new version of the standard has made many improvements in chemical composition, inspection rules, etc. to meet the needs of the modern aluminum processing industry for high-quality aluminum ingots.
3. Comparison of standard frameworks
Standard dimensions GB/T 1196—2017 GB/T 1196—2023 Chemical composition requirements Does not include V and Ti content requirements Increases V and Ti content requirements, and adjusts Zn and Cu content limits Inspection time limit 30 days Inspection time limit is not specified Appearance quality inspection No specific regulations Add sampling regulations for appearance quality inspection 4. Interpretation of technical requirements
Chemical composition:Aluminum ingots are divided into 8 grades (A199.85 to A199.00) according to chemical composition, and each grade corresponds to different limits on impurity element content. For example, the grade A199.85 requires aluminum content ≥99.85% and Zn content ≤0.02%.
Ingot shape and ingot weight:The ingot weight of aluminum ingot is $15~\mathrm{kg}\pm2~\mathrm{kg}, 20~\mathrm{kg}\pm2~\mathrm{kg}, 25~\mathrm{kg}\pm2~\mathrm{kg}$, and the specific weight can be determined by negotiation between the supply and demand parties.
Appearance quality: The surface of the aluminum ingot should be neat and tidy, and slight slag inclusions are allowed, but serious flash and pores are prohibited.
5. Implementation suggestions
To ensure compliance with the requirements of the new standard, enterprises should take the following measures:
- Update the internal quality management system documents and clarify the technical indicators of each brand of aluminum ingot.
- Optimize the production process, pay special attention to the control of chemical composition, and ensure that trace elements such as V and Ti meet the new version of the standard.
- Strengthen inspection capabilities and equip with advanced spectral analysis equipment (such as the method recommended by GB/T 7999) to ensure the accuracy of chemical composition detection.
- Negotiate with suppliers to clarify appearance quality requirements to avoid product failures due to surface defects.
6. Conclusion
The implementation of GB/T 1196-2023 will promote the remelting aluminum ingot industry in my country to move towards higher quality and standardization. Enterprises should actively adapt to the requirements of the new standard to ensure that product quality meets market demand.
