Main characteristics:
1. Adopt convex-concave roll, and the rolling curve is comprised of straightening, tumbling and transition sections, with both straightening and tumbling roles. As a line-contact device, it can achieve full-range straightening and tumbling.
2. Adopt double rolls pressing/straightening principle with constant-pressure load control, turn rigid frame into flexible one, and ensure required pressure on straightening and tumbling of bars. What's more, it can reduce head-tail necking phenomenon and protect mechanical equipments.
3. Adopt electric adjustment and digital display for roll clearance, characterized by high sensitivity and reliability, and convenient operation and maintenance.
4. The hydraulic system, equipped with hydraulic station, adopts ram pump as power source. The overload unloading adopts direct-acting overflow valve, which may maintain the pressure and buffer.
5. The feeder system adopts anti-scratching protective measures, and elevating charging basket adopts plate-dragging organ, which may arrange the materials regularly and also reduce the impacts and noises.
