ما هي عملية الصب والدرفلة المستمرة للنحاس؟

As a trusted B2B supplier with decades of expertise in cable manufacturing equipment, we recognize that superior copper rod quality is the foundation for reliable power cables, building wires, and renewable energy conductors. Copper Continuous Casting and Rolling (CCR) represents the industry-standard integrated process that transforms electrolytic copper cathodes or high-grade scrap into bright, low-oxygen copper rods (typically 8 mm or 12.5 mm) in a single, uninterrupted flow. This advanced Copper CCR Line delivers unmatched efficiency, consistency, and scalability for modern wire and cable producers worldwide.

ال خط نحاسي CCR (المعروف أيضًا باسم Copper Continuous Casting and Rolling Machine) is a fully automated production system that combines melting, casting, hot rolling, cooling, and coiling into one seamless operation. Unlike traditional batch methods requiring separate reheating and handling steps, CCR eliminates interruptions, reducing energy use and material waste while ensuring uniform metallurgical properties.

Developed from proven technologies (including Properzi, SouthWire SCR, and SMS Contirod systems), it produces Electrolytic Tough Pitch (ETP) or Fire-Refined High-Conductivity (FRHC) copper rods ideal for downstream drawing into fine wires. In 2026, with surging demand from new energy projects and data centers, CCR lines remain the preferred solution for high-volume, low-cost, high-quality rod production.

Copper CCR Line Layout and Continuous Casting Process Flow

Detailed Process Flow of a Copper CCR Line

The entire line operates under precise temperature, tension, and cooling control for optimal rod performance:

  1. Melting & Holding: Grade 1 electrolytic copper cathodes or premium scrap are melted in a shaft or reverberatory furnace (maintained at 1150–1200°C) and transferred to a holding furnace via launder for stable temperature and oxidation control.
  2. Continuous Casting: Molten copper is poured into a five-wheel casting machine. A steel belt forms a dynamic trapezoidal mold against the rotating wheel, enabling rapid, uniform solidification into a continuous cast bar. Multi-angle stainless-steel water sprays ensure even cooling.
  3. Bar Preparation: Front traction pulls the bar; a roller shear cuts it to length, followed by straightening, beveling, and burr removal.
  4. Hot Rolling: The bar (at ~900–1000°C) enters a multi-stand two-roller mill (typically 8–14 stands) for progressive diameter reduction while preserving ductility.
  5. Cooling & Surface Treatment: High-pressure water quenching + optional wax or antioxidant coating produces bright, low-oxygen rod (<200–400 ppm oxygen).
  6. Coiling & Packaging: Rear traction feeds an automatic star or basket coiler. Hydraulic systems enable non-stop coil changes (up to 5–8 tons per coil) for 24/7 operation.

Key Advantages: Data-Driven Performance Benefits

Modern Copper CCR Lines outperform traditional routes with measurable gains:

  • Energy Efficiency: Saves 25–35% energy by eliminating reheating steps—critical for sustainable manufacturing in 2026.
  • High Productivity: Capacities from 8–60 tons/hour with automated shear, traction, and coiling for minimal downtime.
  • Superior Quality: Uniform fine-grain structure delivers conductivity ≥101% IACS, excellent drawability, and consistent mechanical properties across long coils (no welds).
  • Cost & Labor Savings: Reduces labor by 30%+ and material loss while supporting mixed cathode/scrap feedstock.
  • Reliability & Safety: Single-base construction, pneumatic tensioning, and automatic power-failure protection ensure stable, safe operation.
