Scope

Scope: This standard specifies the requirements for the classification, recycling, pretreatment, and utilization of raw materials for recycled cast aluminum and aluminum alloy enterprises. This standard applies to the classification, recycling, pretreatment, and utilization of recycled cast aluminum and aluminum alloy raw materials (hereinafter referred to as recycled aluminum raw materials); Main technical content: Typical recycled cast aluminum and aluminum alloy production processes, typical pretreatment processes for recycled aluminum raw materials, When formulating the process technical documents, the quantity ratio of various types of recycled aluminum raw materials should be determined according to the product technical requirements of the processing enterprises and the users' usage conditions; The melting process should adopt the "low temperature immersion" principle to reduce aluminum loss and energy consumption during the melting process; After the melting of the furnace charge, it should be fully stirred, sampled for rapid analysis before the furnace, and the chemical composition should be adjusted according to the test results to meet the standard requirements. After that, refining in the furnace is recommended, and after refining, it should be allowed to stand for a while before starting casting; For aluminum and aluminum alloy casting ingots with different quality requirements, corresponding online purification equipment should be equipped during casting, and if necessary, online hydrogen detection and slag detection instruments can be used to ensure the internal metal purity of the casting ingots. The melting process and equipment can refer to the requirements of GB/T 34640, and the purity can refer to the requirements of GB/T 32186.
