Plate Mill

PLATE MILL — POWER MEETS PRECISION

Quality plate is about metallurgical precision – high strength and toughness at alloying levels that keep costs down and preserve weldability. It is also about maintaining precise thickness across the full width, as well as consistent flatness to assure fit-up in fabrication. For the successful plate producer, the mill is more than the rolling stand(s) at its core. Ancillary processes, in cooling and levelling in particular, are vital to quality, and control of the process is the key to efficient asset utilization. Beyond the operations and the engineering, there is a business – one that supplies some of the most safety-critical applications, and the most demanding customers in all of industry. When you are looking for a reliable and expert partner for your venture in this marketplace, Primetals Technologies is this partner.

Process Know-How

Designing a plate mill is far more than an exercise in mechanical engineering. It is a special and unique example of combining operational efficiency and metallurgical function. Plate products derive their properties from the deformation and temperature path they follow, and this means that the flexibility to roll a broad mix in a single mill must be built into the layout and the machine parameters. These design factors have to be right for all time. Getting them right starts with a complete understanding of process metallurgy, and translating this into a complete and robust design relies on experience. Primetals Technologies has more experience than anyone of the design and supply of modern wide plate mills, allowing us to develop and use engineering tools for the plate mill application specifically.
 

Tools for Successful Design

  • Bespoke Process Models (incorporating metallurgy as well as roll-bite mechanics and heat transfer)
  • Facilities Design Methods (leading to maximized asset utilization under optimal deformation-temperature paths)
  • Finite Element Analysis and Simulation (modern engineering tools to prove and optimize equipment performance)

​Modular Technology

The best designed and installed plate mills guarantee a long operating life, through changing markets as well as emerging and improving mill technology. The key to a sustainable asset is modular technology, allowing upgrades to be made as efficiently as possible in both time and cost terms. The integration skills of Primetals Technologies and our broad base of engineering disciplines, from machine design through process control and metrology, make us an ideal partner in the maintenance and development of the plate mill as a lasting asset. The potential of the modular approach is wide-ranging too. It can equip a new operator for a lower-volume market at entry with scope for future capacity growth, or it can guide an established operator into new product markets. Future-proofing of a customer's business may be the greatest challenge for any technology provider, but in plate mills, Primetals Technologies is your partner to provide it.
