Details of Our Flat Copper Wire Rolling Mills
Our rolling mills are engineered for high-precision production of superconducting and special copper wires. The machines are capable of producing enamelled monolithic wires in both round and rectangular profiles, as well as wire-in-channel (WIC) and cable-in-channel (CIC) integrated conductors, meeting the stringent dimensional and quality requirements of advanced superconducting applications.
The production line achieves speeds of up to 250 m/min, enabling high-efficiency rolling of round copper wire into precise flat profiles. The system maintains tight dimensional tolerances and consistent material properties even at full speed, ensuring reliable performance for superconducting wire applications.
The rolling mill delivers precisely controlled reduction ratios of 10–20% per pass to achieve the target flat wire dimensions. The number of passes can be adjusted based on wire size and material type, ensuring uniform thickness, consistent width, and minimal internal stress along the entire wire length. This multi-pass process provides the accuracy and reliability required for high-quality superconducting flat copper wire, ideal for MRI scanners and silicon crystal growth magnet applications.
