  • Ansteel was planning a new, high-performance greenfield hot strip mill in Chaoyang, China.
  • It required a Coilbox™ to allow maximum processing flexibility for a wide variety of products and operating conditions.


  • Inexperienced domestic suppliers were considered, but ultimately Ansteel turned to us for our world-class, leading coilbox technology.
  • The Hatch Coilbox™ demonstrated the processing speeds and reliability required for the new hot strip mill.


  • The Anling Coilbox™ has the highest coilbox thread speed of 5.0 m/s and the highest reliability of coiling with no ovality.
  • The new Coilbox™ has a simpler mandrelless transfer system than previous designs.
  • The new Coilbox™ has the most flexible operator interface to allow for manual intervention when needed.
