The upward continuous casting and rolling line represents a new generation of copper rod production technology that combines high efficiency, excellent metal purity, and stable performance. This process is widely used in manufacturing oxygen-free copper rods and other high-conductivity materials for electrical wire, cable, enameled wire, and electronic components.

1. What Is Upward Continuous Casting and Rolling?

Unlike traditional downward casting, the upward continuous casting process uses a vertical crystallizer where molten copper is drawn upward by means of crystallization and solidification. The cast rod is then directly fed into the rolling mill for continuous hot rolling, producing copper rods with uniform structure and smooth surface.

This “casting + rolling” integration ensures:

• Stable crystal structure and fine grain size

• Reduced oxygen content and excellent conductivity

• Compact layout and easy operation

• Energy-saving and environmentally friendly production

2. Main Components of the Line

A complete upward continuous casting and rolling line typically includes:

• Melting and holding furnace – Melts electrolytic copper and maintains a steady temperature.

• Upward casting machine – Produces cast rods of various diameters (usually 8 mm – 20 mm).

• Rolling mill – Performs continuous rolling to the required size, ensuring high precision.

• Coiling system – Automatically collects the finished copper rods for easy handling and storage.

• Control and monitoring system – Uses PLC and touch-screen operation for stable and intelligent production.

• 

3. Advantages of Upward Continuous Casting and Rolling

• High conductivity: Oxygen-free copper rods with purity up to 99.99%.

• Smooth surface finish: Ideal for further wire drawing and cable extrusion.

• Energy efficiency: Continuous process reduces reheating loss and improves yield.

• Compact footprint: Space-saving design suitable for both large and medium-sized factories.

• Low maintenance: Reliable operation with long equipment life.

•
