Introduction
Interpretation of the standardization of the utilization of deformed aluminum and aluminum alloy waste
| Waste grade | Treatment method | Applicable scenarios |
|---|---|---|
| Primary waste | Directly put into the furnace for use, no need for reprocessing | Applicable to high-quality aluminum alloy production |
| Secondary waste | Directly put into the furnace for use, some need pretreatment | Suitable for general aluminum alloy products |
| Tertiary waste | Whether to be reprocessed depends on the company's situation | Applicable to production with lower quality requirements |
| Fourth-level scrap | Must be reprocessed before use to ensure stable chemical composition | Suitable for processing scraps whose chemical composition cannot be determined |
Background of standard formulation and analysis of technological evolution
With the widespread application of aluminum alloys in the fields of construction, packaging, transportation, etc., the recycling and utilization of scraps is particularly important. The introduction of GB/T 34640.3-2017 standard aims to standardize the utilization process of deformed aluminum and aluminum alloy scraps, improve resource utilization and reduce environmental pollution.
Reprocessing and melting and casting technology
Double-chamber furnaceAs an advanced smelting equipment, it plays an important role in the reprocessing process. It operates in a low-oxygen environment, which can reduce the burning loss of aluminum liquid and achieve uniform alloying through electromagnetic stirring. During the melting and casting process, it is recommended to use online purification equipment (such as hydrogen meter and slag meter) to ensure that the purity of aluminum alloy products meets the requirements of GB/T 32186.
Implementation suggestions
To ensure efficient and compliant waste utilization, enterprises should:
- Establish a complete waste classification and identification system
- Equip with advanced compounding and melting and casting equipment
- Strictly implement environmental monitoring and emission standards
- Perform chemical composition analysis and process optimization regularly
