When you specify a compact mill system to convert copper round drawn wires into drawn rectangular wires, there’s no doubt production efficiency and speed will be among your most significant criteria when choosing the mill. The flexibility to address different gauges and intuitive user controls will also be important factors in selecting the right machine. This blog post will describe a rolling mill that satisfies these requirements and more to produce a wide range of rectangular wires quickly and reliably.
Cold rolling creates a more malleable and pliable product, making it particularly attractive for copper wire. At REDEX, we developed Rectangular Wire Micro Rolling Units — machines that perfectly adapt the input wire diameter to the finished rectangular wire, achieving a wide range of sizes according to DIN-BS or IEC standards. Not only do these units offer flexibility in wire sizes, they also incorporate high-performance features and design elements that optimize flexibility and efficiency, such as:
- High speed. Rectangular Wire Micro Rolling Units can achieve speeds of up to 100 meters/minute.
- Space-saving structure. The unit has two-high 150-millimeter diameter breakdown rolls, die holder, 72-millimeter diameter edger and a 400-millimeter diameter two-wheel capstan.
- Two-high breakdown. A two-roll breakdown creates a flat and uniform lay and gives copper excellent tensile strength and ductility without the complexity and additional space of a four-high breakdown. With fewer rolls to replace and maintain, the units require less downtime for maintenance.
- Complete tension control. Dancers are located before the continuous process and after the micro rolling mill for complete tension control.
- Micro edger. The integrated micro edger ensures a proper width and eliminates edge defects, boosting product quality as well as machine efficiency and reliability.
- Liquid filtration. The unit includes a liquid spray filtration system that eliminates contaminants, ensuring smooth operation while reducing downtime for cleaning. The result: better product quality.
- Advanced HMI interface. When producing various wire diameters, it pays to have an advanced HMI interface to easily manage each job. The mill’s HMI interface synoptically monitors the unit in real time while the display shows a full picture of the process. Users can easily control the unit’s operation via its readily accessible operator settings.
Rectangular Wire Micro Rolling Units accommodate widths from 1 to 9.5 millimeters and thicknesses from 0.5 to 3.8 millimeters.
Taken together, REDEX Rectangular Wire Micro Rolling Units offer the high speed, efficiency and flexibility that are critical to producing high-quality rectangular wires while also meeting challenging throughput demands. You can see our Rectangular Wire Micro Rolling Unit in action in this video.
