Typical recycled cast aluminum and aluminum alloy production process, typical recycled aluminum raw material pretreatment process, the batching should be based on the product technical requirements of the processing enterprise and the user's usage, formulate process technical documents, determine the quantity ratio of various types of recycled aluminum raw materials ; The melting process should adopt the "low temperature immersion" principle to reduce aluminum loss and energy loss during the melting process; the charge should be fully stirred after melting, samples should be taken for rapid analysis in front of the furnace, and the chemical composition should be adjusted according to the test results. After meeting the standard requirements, it should be Refining is carried out in the furnace, and it must be allowed to stand after refining before casting begins. For aluminum and aluminum alloy ingot products with different quality requirements, corresponding online purification equipment should be equipped during casting. If necessary, online hydrogen testing, slag testing, etc. can be used Instruments to ensure the internal metal purity of the ingot. The smelting process and equipment can be implemented according to the requirements of GB/T34640. The purity can be implemented according to the requirements of GB/T32186.
