This device is a vertical straightening machine with multiple skew rolls (mainly seven-roll). Obviously, it can resolve head-tail bends, eliminate slight ovality and remove oxidized iron sheet.
1.Adopt Xi'an RG's specialized complex roll system design and have high straightening precision.
2. Adopt SIMENS’s full-digital gear, thus its performance can be fully reflected.
3. It can achieve automatic control, sound/light alarming system for fault detectors from end to end, it can make the operation easy and convenient.
4. It is equipped with special hydraulic system to maintain the pressure and buffer, thus the finished product rate may be maximum improved.
5. The anti-scratching protective measure and flexible feeder system and soft discharge device are adopted for rare and valuable metal.
