Alüminyum Çubuk Sürekli Döküm ve Haddeleme Hattı Nedir?

In today’s demanding wire and cable industry, the quality of the aluminum rod directly determines the performance, reliability, and cost-efficiency of the final conductor. Whether you are producing overhead transmission lines, power cables, building wires, or automotive harnesses, consistent high-conductivity aluminum rod is non-negotiable.

O Aluminum Rod Continuous Casting and Rolling Line (commonly known as Aluminium CCR Line veya Al CCR) is the industry-standard integrated solution that transforms aluminum ingots or scrap into premium oil-free conductive rods in a single continuous process. This technology eliminates intermediate reheating, reduces energy consumption, and delivers rods with superior microstructure, mechanical properties, and surface cleanliness — exactly what modern cable manufacturers require for high-speed wire drawing and stranding.

What is an Aluminum Rod Continuous Casting and Rolling Line?

An Aluminum CCR Line is a complete, automated production system that combines melting, holding, continuous casting, rolling, cooling, and coiling into one synchronized process. It produces round aluminum and aluminum alloy rods (primarily Ø9.5 mm, Ø12 mm, and Ø15 mm) that serve as the critical raw material for electrical conductors.

Annual production capacity typically ranges from 6,000 to 35,000 tons, with hourly output between 2.5 and 7.5 tons per hour depending on configuration and alloy. The final rods are oil-free, ensuring excellent compatibility with downstream drawing lubricants and insulation materials used in cable manufacturing.

Core Components of a Professional CCR Line

A high-performance Aluminum CCR Line includes:

• Melting furnace (induction, gas, or oil-fired) and holding furnace with refining capability
• Launder system with optional online degassing and filtration units
• 4-wheel horizontal continuous casting machine (crystallization wheel diameter typically 1,400–2,300 mm)
• Front traction / straightening unit and roller shear
• Optional medium-frequency induction heating furnace for precise temperature control
• Continuous rolling mill (11–15 stands; 2-roll, 3-roll Y-type, or hybrid configurations)
• Cooling, lubrication, and quenching system with water blow-off
• Twin-basket or centrifugal continuous coiler with active traction
• Advanced PLC + HMI electrical control system with remote monitoring and synchronization across all sections

Detailed Process Flow

1. Melting & Holding — Pure aluminum ingots or clean scrap are melted and held at precise temperature. Refining, degassing, and slag removal ensure high purity.
2. Sürekli Döküm — Molten aluminum flows through the launder into the 4-wheel casting machine, solidifying into a trapezoidal bar (typical cross-section 1,600–3,300 mm²).
3. Shearing & Preparation — Non-conforming sections are cut; the bar front is prepared and fed into the rolling mill.
4. Rolling — The bar passes through multiple rolling stands (typically 11 stands for Ø15 mm, 13 for Ø12 mm, 15 for Ø9.5 mm). Different roll configurations (2-roll or 3-roll Y-type) are selected according to alloy to achieve optimal roundness, surface finish, and mechanical properties.
5. Cooling & Surface Treatment — Controlled cooling and emulsion removal produce clean, oil-free rods.
6. Coiling — Rods are wound into large, stable coils using twin-basket or centrifugal coiling systems with pre-deformation and automatic tail handling.

Technical Parameters (Typical Configurations)

Key Product Features & Technical Advantages

• Superior Metallurgical Quality — Smooth, turbulence-free casting and controlled rolling produce dense billets with excellent grain structure, high conductivity (typically >61% IACS for EC1350), and consistent mechanical properties.
• Excellent Drawability — Uniform deformation and clean, oil-free surface significantly reduce wire breaks during high-speed drawing — critical for cable production efficiency.
• Alloy Flexibility — Configurable for 1xxx (EC1350), 3xxx, 6xxx (6101/6201), and 8xxx (8176/8030) series — allowing cable manufacturers to optimize conductivity vs. strength/creep resistance.
• High Efficiency & Energy Saving — Continuous process eliminates reheating; advanced cooling and drive systems reduce operating costs.
• Automation & Safety — Full synchronization of casting, rolling, and coiling; stainless steel protective covers; remote monitoring and diagnostics.
• Uzun Hizmet Ömrü — High-quality alloy rolls with easy maintenance access.

Applications in the Cable Industry

Aluminum CCR rods are the foundation for:

• Overhead conductors (AAC, AAAC, ACSR)
• Power cables (LV/MV)
• Building wires and cables
• Automotive and EV wiring harnesses (lightweighting advantage)
• Renewable energy cabling (solar & wind)
• Aluminum wire drawing for subsequent stranding and insulation

Alloy selection allows cable designers to balance conductivity, tensile strength, creep resistance, and weight — directly impacting ampacity, sag, and installation performance.

Quality Assurance, Testing & International Standards

Professional CCR lines incorporate rigorous in-line and laboratory quality controls:

• Dimensional accuracy and roundness verification
• Surface inspection for cracks, inclusions, folds, or kinks
• Electrical conductivity testing (typically ≥61% IACS for EC1350; alloy-dependent for 8xxx/6xxx series)
• Tensile strength and elongation measurement (critical for drawability and final cable mechanical performance)
• Metallographic examination of grain structure when required

Rods produced on well-configured CCR lines consistently meet or exceed ASTM B233, IEC, and EN standards for electrical aluminum wire rod. The clean, oil-free surface and uniform properties minimize wire breaks during drawing — a key productivity driver for cable plants.

Environmental, Energy & Sustainability Benefits

Modern CCR lines incorporate multiple sustainability features:

• Closed cooling systems with vapor extraction reduce water consumption and emissions
• Fume collection and protective covers (hydraulic flip-type) improve workplace safety and environmental compliance
• Significantly lower energy use compared with traditional reheat processes
• Reduced production slag and higher material yield
• Option for emulsion filtration and recycling systems

These features support cable manufacturers’ ESG goals while lowering operating costs.
