Equipment design

Roll stack, tension, drive, and automation designed as one system.

JINYE specifies rolling mill projects around the production recipe: material grade, target reduction, incoming and outgoing thickness, strip width, roll force, coolant plan, and plant automation requirements.

  • Gauge control target down to ±0.002mm under qualified process conditions.
  • Energy-focused mill design with a target power saving of around 30%.
  • Multi-material rolling capability for stainless steel, silicon steel, and carbon steel.
  • AGC/AFC automation options for repeatable production and reduced operator burden.
