In today\u2019s 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.<\/p>\n\n\n\n

Le Aluminum Rod Continuous Casting and Rolling Line<\/a><\/strong> (commonly known as Aluminium CCR Line<\/strong> ou Al CCR<\/strong>) 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 \u2014 exactly what modern cable manufacturers require for high-speed wire drawing and stranding.<\/p>\n\n\n\n

What is an Aluminum Rod Continuous Casting and Rolling Line?<\/h2>\n\n\n\n

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 \u00d89.5 mm, \u00d812 mm, and \u00d815 mm) that serve as the critical raw material for electrical conductors.<\/p>\n\n\n\n

Annual production capacity typically ranges from 6,000 to 35,000 tons<\/strong>, with hourly output between 2.5 and 7.5 tons per hour<\/strong> 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.<\/p>\n\n\n\n

Core Components of a Professional CCR Line<\/h2>\n\n\n\n

A high-performance Aluminum CCR Line includes:<\/p>\n\n\n\n

    \n
  • Melting furnace (induction, gas, or oil-fired) and holding furnace with refining capability<\/li>\n\n\n\n
  • Launder system with optional online degassing and filtration units<\/li>\n\n\n\n
  • 4-wheel horizontal continuous casting machine (crystallization wheel diameter typically 1,400\u20132,300 mm)<\/li>\n\n\n\n
  • Front traction \/ straightening unit and roller shear<\/li>\n\n\n\n
  • Optional medium-frequency induction heating furnace for precise temperature control<\/li>\n\n\n\n
  • Continuous rolling mill (11\u201315 stands; 2-roll, 3-roll Y-type, or hybrid configurations)<\/li>\n\n\n\n
  • Cooling, lubrication, and quenching system with water blow-off<\/li>\n\n\n\n
  • Twin-basket or centrifugal continuous coiler with active traction<\/li>\n\n\n\n
  • Advanced PLC + HMI electrical control system with remote monitoring and synchronization across all sections<\/li>\n<\/ul>\n\n\n\n

    Detailed Process Flow<\/h2>\n\n\n\n
      \n
    1. Fusion et maintien<\/strong> \u2014 Pure aluminum ingots or clean scrap are melted and held at precise temperature. Refining, degassing, and slag removal ensure high purity.<\/li>\n\n\n\n
    2. Coul\u00e9e continue<\/strong> \u2014 Molten aluminum flows through the launder into the 4-wheel casting machine, solidifying into a trapezoidal bar (typical cross-section 1,600\u20133,300 mm\u00b2).<\/li>\n\n\n\n
    3. Shearing & Preparation<\/strong> \u2014 Non-conforming sections are cut; the bar front is prepared and fed into the rolling mill.<\/li>\n\n\n\n
    4. Rolling<\/strong> \u2014 The bar passes through multiple rolling stands (typically 11 stands for \u00d815 mm, 13 for \u00d812 mm, 15 for \u00d89.5 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.<\/li>\n\n\n\n
    5. Refroidissement et traitement de surface<\/strong> \u2014 Controlled cooling and emulsion removal produce clean, oil-free rods.<\/li>\n\n\n\n
    6. Coiling<\/strong> \u2014 Rods are wound into large, stable coils using twin-basket or centrifugal coiling systems with pre-deformation and automatic tail handling.<\/li>\n<\/ol>\n\n\n\n
