Increased rate with sophisticated staggering of plates

The thermo-mechanical rolling process significantly improves plate properties in terms of strength, toughness, weldability and workability.

For this purpose, the rolling process is divided into different temperature and reduction ranges. Our X-Pact® Thermo-mechanical Rolling ensures multiple plates are rolled nested in a batch to maximize productivity.

X-Pact® Thermo-Mechanical Rolling

Customer challenges addressed

  • Optimized mill usage during cooling phases of thermo-mechanical rolling
  • Increasing of productivity
  • Reducing of expensive alloys

Key features

  • Production of micro-alloyed high strength steel with higher ductility requirements
  • Stable reproducible thermo-mechanical rolling process
  • Better thermo-mechanical production rate with sophisticated staggering of plates in the mill area
  • Increase operation time
  • Increases productivity with multi-plate rolling
  • Reduces the use of expensive alloys
  • Generates reproducible plate properties

Highlights

  • Reproducible plate properties

    Our X-Pact® automation system ensures a reproducible plate properties and leads to a reduction of costs for testing the sheet metal qualities. This ensures less material loss and failure rates.

  • Multiple plate rolling

    Types of multiplate rolling

    Static batch: In the static batch, other similar plates are rolled in the TM break of the first plate in a group. After that, all the plates are moved back together through the mill stand and then all are finish-rolled, starting with the first plate. The static batch productivity is very high.

    Conti batch: In the conti batch, the plates are nested in such a way that the number of sheets in the batch is always constant. One plate is always added to the batch after a previous plate has been finish-rolled. The reproducibility of the continuous batch is very high because the furnace discharge times are always constant.

    Dynamic batch: In the dynamic batch, there is free, highly flexible rolling planning for a wide variety of plates and rolling modes with the aim of maximizing throughput
