Primetals Technologies revamps two wire-rod mills for China’s Zenith Steel

  • Upgrade increases rolling speed to 105 m/s
  • Expanded product line allows entry into fine grain rebar markets
  • Integrated solution includes electrical/automation revamp


Zenith Steel (Changzhou Zhongtian Iron & Steel) in Changzhou, Jiangsu Province, China, has signed a contract with Primetals Technologies to revamp two wire-rod outlets located in Changzhou. New equipment will allow thermomechanical rolling to produce fine grain rebar at a significantly reduced cost. The wire-rod mills will operate at a speed of 105 m/s. Commissioning is planned for early 2016.


Included in the scope of supply are mini-finishing blocks, a Morgan Intelligent Pinch Roll and new laying head. After the new equipment’s installation, the revamped mills for this privately owned, midsized steelmaker will be able to roll on the same outlet rebar ranging in diameter from 6.0 mm to 16 mm, and rod sizes from 5.5. mm to 20 mm. In addition, Primetals Technologies is providing an integrated solution with electric and automation upgrades for the mills.


Delivery is expected in third quarter 2015 for both rod outlets with commissioning by early 2016. The contract includes site supervision and services during the installation. At Zenith Steel, a continuous bloom caster from Primetals Technologies has been in operation since July 2013.
