Inclusions
can be divided into 2 broad classes:
- Non-deformable inclusions - such inclusions are hard
at rolling temperatures and maintain their original shape as
the steel is deformed.
- Deformable inclusions - such species are soft at
steel rolling temperatures and deform and elongate as the steel is
rolled.
The
following animation shows how MnS inclusions in a steel are
elongated during hot rolling of plate. Start the animation to see
how the inclusions change shape during rolling:
