PL/TCM MMK, Russia

The world’s most powerful tandem cold mill

Responsible for the complete package, we supplied the world’s most powerful PL/TCM to Russian steel producer Magnitogorsk Iron & Steel Works (MMK). Our customer uses the mill to produce a large range of products, from low-carbon to high-strength steels. The plant went on stream in May 2011. Particularly impressive is that this PL/TCM features the world's longest turbulence pickling line. The mill consists of five stands and is equipped with state-of-the-art rolling technologies such as:

  • 4-high design with CVC® plus
  • Positive and negative work roll bending
  • Multizone cooling and DS system
  • X-Pact® electric and automation system
  • Inline strip inspection with Rotary Inspect

It achieves a maximum rolling force of 35MN. That makes it the most powerful TCM anywhere in the world.
