The diagram shows the axial shifting of the
“S-shaped” CVC work rolls. The roll gap can
be selectively adjusted to be either:
1 Parallel 2 Convex 3 Concave

Production process.
Steel-making
The steel for hot-dip coated sheet is
produced in basic oxygen steel plants
with converter capacities of 260 t and
380 t. The process is computer-controlled
and fully automated. In the
course of the refining cycle, the oxidation
of carbon and accompanying elements
in the pig iron, is aided by additional
argon injection through the
converter bottom to achieve improved
mixing. Without over-refining the heat
the preconditions for keeping within very
tight analysis limits are created and a
good level of steel cleanness is achieved.
Vacuum treatment and additional ladle
metallurgy make it possible to produce
steels with extremely low carbon levels
