Finishing Mills

  • Finishing mill is the top cross 45° high-speed wire rod finishing mills designed for producing wire rod.

  • Rolling by 10 unit rack continuous micro-tension rolling mill, the Φ17~Φ21 mm of rolled piece can be rolled into Φ5.5~Φ16 mm wire rod.

  • The mill guaranteed exit speed is 90 m/s. (When the final wire rod size is Φ5.5 mm)

Details Description

  1. The mill unit consists of 5 stands φ230 rolling mill and 5 stands φ170 rolling mill, the strength of the unit is more powerful.
  2. The unit uses top cross 45° layout, reducing equipment center of gravity height, increasing the stability of the unit.
  3. Adjacent rolling mill stand are arranged at 90º to each other, achieving no-twist rolling.
  4. Roll box with plug-in structure, cantilevered roll ring, cabinets equipped with eccentric mechanism for adjusting the roll gap. Eccentric sleeve is equipped with an oil film bearing and roller shaft, fixing roller ring with taper sleeve at the cantilever roller shaft end.

Mill Roll of Finishing Mills

Mill roll, a tool that plastically deforms the (rolled) metal and an important consumable component that determines the efficiency of the rolling mill and the quality of the rolled material. Mill roll is an important part of the rolling mill, utilizing the pressure generated by a pair or group of rollers rolls to roll the steel. It is mainly subjected to dynamic and static loads during rolling, wear and temperature changes.
