Aluminum Hot Rolling Mill


Primetals Technologies provides a full range of aluminum hot rolling mills for both new and revamp projects.

As the demand for higher quality and greater quantities of rolled aluminum increases, so do demands on production equipment. Primetals Technologies' solution offers a combination of mechanical actuators, electrical and automation control systems, and applied process know-how to deliver gauge, profile/flatness, temperature, and surface quality with the highest level of consistency. With our flexible mill configuration, high-quality strip can be rolled in capacities between 100,000 to 1,000,000 tonnes per annum.

Aluminum Hot Rolling Mills — Advanced technology for high-quality products

Primetals Technologies' aluminum hot rolling mill portfolio and experience comprises:

  • Single and Two-Stand Roughing Mills
  • Twin Coiler Reversing Mills
  • Tandem Finishing Mills (three, four, and five stands)
  • Mini Mills (integrating caster with Tandem Finishing Mill)
  • Plate Mills

To meet the needs of the aluminum market, our hot mill solutions feature a range of common technological enhancements to increase performance, operability, safety, and surface quality. These include:

  • SmartCrown roll contour, which guarantees enhanced profile and flatness control
  • Heavy work roll bending for improved profile control
  • Integral Solenoid Valve (ISV) spray system for improved profile and flatness control
  • Interstand strip cooling for improved finishing mill throughput
  • Edge trimmer delivers improved yield and reduces cold mill strip breaks
  • EdgeMon for improved strip edge quality
  • Roll gap sensor for improved profile control and throughput
  • Mill Stabalization Device (MSD) for reduced cobbles and improved mill availability
  • Variable angle roller tables for optimum bottom surface quality
  • Rapid, side shifting work roll change for improved mill availability
  • Fully hydraulic vertical edger for improved yield
  • Hydraulic shears for improved mill availability
  • Automatic coil welder for enhanced operator safety
  • Remote belt tracking on the wrapper for operator safety
  • Pressure plate filter (Schneider) for improved surface quality
