Aluminum Cold Rolling Mill


Primetals Technologies' aluminum cold rolling mills offer a blend of innovative design and proven technology for both new and revamp projects.

From transport to construction, from packaging to automotive, each end market for flat rolled aluminum comes with its own set of production challenges. Primetals Technologies' aluminum portfolio provides you with the optimum equipment, correct mill setup, and control systems crucial to meeting exacting quality requirements. Our online modelling solutions feature fully integrated process control, automation and drive systems, delivering exceptional rolling results and enabling tight tolerance strip production with maximum yield.

Aluminum Cold Rolling Mills — Solutions for high-precision rolling

Primetals Technologies' cold mill portfolio comprises:

  • Breakdown mills
  • Thin-strip mills
  • Tandem mills (two, three, and four-stand)

Offering both 4-high and 6-high mills stand designs, we can provide an extensive range of proven technologies for greenfield sites and modernizations of existing mills that can be tailored to meet your particular rolling needs. Our online process models connect to our fully integrated process control and automation drive system to optimize the rolling process for you.

Performance actuators offered with our mills improve mill production, coil yield, strip flatness, and quality. These include:

  • Universal Crown Control Mill (UC-MILL) for excellent strip flatness and surface quality
  • Integral Solenoid Valve (ISV) spray system for improved profile and flatness control
  • Induction heating maximises coil yield and eliminates flatness errors
  • Short coil handling time increases mill availability
  • Edge wipe unit which removes edge beads to improve strip dryness
  • Interstand cooling for tandem mill solutions increases rolling speed
  • Schneider Coolant Filtration maximises mill availability and minimizes waste
  • Heavy-duty Air Bearing ShapeMeter (ABSM) roll provides a highly sensitive solution for accurate flatness feedback
  • Vapor Shield fume cleaning and rolling oil recovery reduces harmful emissions, thereby improving your environmental credentials
