Producing copper bars involves melting copper scrap or refined copper at approximately 1, 200C to 1, 500°C in a furnace, removing impurities, and pouring the molten metal into molds. It requires significant safety equipment—such as fire-resistant clothing and fullface shields—due to extreme temperatures, followed by cooling and finishing to produce solid, durable ingotsKey Steps in Copper Bar Production
Raw Material Preparation: Copper scrap (old pipes, wires, motors) is cleaned, selected, and often pre-heated.
Melting: The copper is melted in a crucible furnace (e.g., Devil Forge 4kg) at temperatures exceeding 1, 100℃
Refining (Optional): Impurities are removed, and a deoxidation reduction process may be performed to ensure high purity.
Finishing: Once cooled, the bars are removed from the mold, cleaned, and sometimes subjected to hot or cold rolling for specific shapes.
