Leveling and Cut-to Length (CTL) Lines
Leveraging advanced engineering expertise, Fan Avaran Borna has designed and manufactured state-of-the-art Cut-to-Length (CTL) lines based on modern standards. Focused on the ultimate quality of the sheet surface, these lines are capable of processing steel coils with ultra-high tensile strength (up to 1600 N/mm²). The primary distinction of this machinery lies in Fan Avaran Borna’s unique leveling philosophy. This system is built upon a cascade of multiple levelers (ranging from a minimum of two units—including a pre-leveler and main leveler—to a maximum of three). By utilizing Artificial Intelligence (AI) for precise adjustment and applying calculated tensile force between the units, these lines simulate a process similar to "Tension Leveling." The result of this process is an increase in the uniform plasticity of the material, the complete elimination of internal residual stresses, and the delivery of an ideal surface that meets even the most stringent standards required for laser cutting applications.
To complete the production process and achieve maximum efficiency and quality, Fan Avaran Borna’s coil-to-sheet lines can be equipped with a suite of advanced peripheral machinery. These machines facilitate greater automation and more precise control: ●Shearing Systems (Guillotines): ◦Rotary Shear: For high-speed, continuous cutting. ◦Flying Shear: For cutting while the strip is in motion, without stopping the line. ◦Angled Shear: For producing specific sheets with non-rectangular (oblique) angles. ●Side Trimmer: For trimming sheet edges and setting the precise, custom width of the final sheet. ●Automatic Stacker: For the orderly stacking of cut sheets, reducing the need for manual labor at the end of the line. ●Inspection and Quality Control Table: A mechanism for the visual and physical inspection of sheets prior to packaging. ●Cutting and Surface Monitoring System: Intelligent control of surface quality and real-time monitoring of cutting operations to ensure defect-free output.
●Longitudinal Cutting Accuracy: ±0.2 mm ●Max. Tensile Strength: 1600 N/mm² ●Coil Weight Capacity: Up to 45 Tons ●Cut Length Range: 300 mm to 12,000 mm ●Max. Line Speed: Up to 120 m/min ●Sheet Width Range: 600 mm to 2000 mm ●Sheet Thickness Range: 0.3 mm to 20 mm
●Multi-Stage Leveling with Tension Control Mechanism Utilizing a multiple-unit configuration (pre-leveler and sequential levelers) rather than a standalone unit ensures that Coil Set and Crossbow defects are completely eliminated. This feature is vital for industries requiring perfectly flat sheets with zero spring-back. ●Automatic Speed Control and Intelligent Synchronization The use of advanced control systems ensures all units operate synchronously. This coordination prevents unwanted elongation or buckling (bunching) of the sheet along the line, guaranteeing product uniformity. ●Burr-Free Cutting The high quality of the cut edges eliminates the need for secondary processes (such as grinding or deburring) and enhances safety during sheet handling. ●Modular and Customizable Design This feature allows the production line layout to be arranged precisely according to the specific needs of the factory (regarding floor space and product type), leading to investment optimization. ●Capability to Process a Wide Range of Materials The ability to work with various materials—including Carbon Steel, Stainless Steel, Galvanized Steel, Aluminum, and Copper—increases the line's flexibility and enables it to meet diverse market demands.
