The copper alloy smelting and casting process and method mainly include the following steps:
1. Raw material selection and preparation: The main component of copper alloy is copper, but other elements such as zinc, tin, and aluminum are often added to change its properties. The raw materials can be pure metals or waste materials containing target alloy components, which need to be dried and cleaned.
2. Smelting: The raw materials are heated to high temperature and melted in a furnace (such as a medium-frequency induction furnace). Refining agents may be added during the smelting process to remove impurities.
3. Alloying and stirring: Other elements are added to the molten copper to form an alloy. The melt needs to be fully stirred to ensure uniform composition, and gas or agents may be used to purify the melt.
4. Casting: The purified melt is poured into a mold to form a primary casting. The mold can be a sand mold, a metal mold, etc.
5. Subsequent processing and treatment: The primary casting undergoes mechanical processing, heat treatment and other processes to finally form a copper alloy product with the required shape and performance, and undergo quality control.
Through the above steps, the smelting and casting process of the copper alloy can be completed to obtain high-quality copper alloy products.
