Fin-bar straightening & calibration machine

    Fin-bar straightening & calibration production line consists of fin-steel calibration machine (including the horizontal correcting, bending straightening and fixed-length devices) cutting machine and force-feeding conveyors. This production line is one of the key equipment to ensure the welding quality of the membrane wall, mainly used in fin-steel’s pre-heater before welding membrane wall tube panel, to ensure the welding quality. Tempered discal-shaped fin-bar processed through this production line, according to the size of the tube to calibration the fin-steel, then horizontal correcting and bending straightening to meet the requirement of the front welding , and last according to the length of pipe to cut off.

    In order to make the tempered fin-steel to calibration smoothly, pre-horizontal correcting device is equipped in the calibration wheel.

- Adopting secondary calibration.
- Using five roller leveling method, in which two rolls take the initiative to roll.
- Using five roller straightening ways, in which two rolls take the initiative to roll.
- The fixed-length fin-steel device equipped with pulse encoder, to scale the length of the Fin-steel.
- Force-feeding conveyors of Fin-steel, whose transmission speed <8m/min.
- Fixed-length fin-steel cutting off production line using imported PLC as a control unit, with strong anti-interference and stable performance.
