2. Precise Process Flow
Grade 1 and Grade 2 red copper scraps (charging) → reverberatory furnace (melting) → launder (protection of melt) → tundish → continuous casting machine(cast bar) → cast bar treatment (roller shears → straightener → trimmer → burr shaver) → feed-in device (motorized feed-in) rolling mill (rolling) → cooling device for copper rod → rod winding device→ star-shaped coiler
