Siemens VAI solution for dry-type skin passing
Skin pass control to meet highest
quality demands
The expectations of end customers for
steels are constantly rising. Deep-drawing
sheet steel, for example, needs to be
almost 100% flat and should not exhibit
any stretcher strains. All this makes skin
pass rolling an important process that
calls for optimization. Our skin pass
control with self-optimizing parameters
can help you safely master these
challenges – in different modes to suit
different requirements:
Skin pass control via the rolling force
Skin pass control via the strip tension
Skin pass control in mixed tension-force
mode
Skin pass control on the basis of the
patented advanced mass-flow concept
This results in a uniform elongation and a
texture – across the entire strip – that
your customers want.
And what is more: Our process models
always have the skin pass mode under
control – whether for 2-stand or singlestand
and inline skin pass mills.
Dry-type skin pass rolling
For exposed automotive parts and a wide
range of household appliances, strip
producers are increasingly required to
supply final products which are skin
passed and free of wet skin passing
agents. SIROLL CIS CM improved solution
for dry-type skin passing is based on roll
cleaning which features the use of
rotating and oscillating wire brushes for
the work rolls and oscillating cleaning
brushes for the backup rolls.
Main benefits:
Cost savings since no wet skin passing
agents are required
Improved adhesiveness of strip surface
for painting
No more „brown staining“ during
storage
No disposal costs for wet skin passing
agents
