Reversing cold mills
Advanced technology
Principle design of a 2-stand reversing cold mill
Single-stand reversing cold mills
Depending on the product mix, rolling
capacities between 200,000 and
600,000 t/a are possible in a single-stand
cold rolling mill. Rolling schedules can be
carried out with an even or uneven
number of passes to maximize mill
availability and performance. Flatnessmeasurement
systems mounted on one
or both sides of the mill ensure optimum
flatness control. In addition to work-roll
bending and shifting, Siemens VAI
reversing cold mills are equipped with
multi-zone cooling to meet the highest
demands on flatness.
2-stand reversing cold mills
Following the introduction of mini mills
in North America, a new generation of
reversing cold mills has emerged which
combines the flexibility of single-stand
reversing mills with the capacity of
conventional coil-to-coil tandem mills at
substantially reduced investment costs.
Steel rolled in 2-stand reversing cold mills
from Siemens VAI is suitable for highest
quality applications, offering the best
possible performance in terms of product
quality and productivity. Ideal for rolling
capacities from 300,000 t/a of thin-gauge
products to 1,000,000 t/a and higher for
heavy-gauge products.
4-high and 6-high technology
Depending on the product mix and the
quality requirements, Siemens VAI offers
4-high or 6-high mill stands to meet the
customer’s overall requirements. Both
mill stand types are equipped with
flatness control solutions using SIROLL CIS
Siflat or Planicim® for measurement and
the SIROLL CIS Smartcrown® roll contour for
the work or intermediate rolls.
