The
characteristics of graphite cast steel rolls are
similar to adamite rolls, but it makes a feature
of presenting a small amount of graphite which
increase the resistance to firecrack and scale
adhesion, and are suitable for blooming or
roughing operation.

Application:
|
| These rolls are
being used on roughing stands of
hot strip mill and roughing stands
of 2-Hi reversing plate mills.
These rolls are being used in
blooming mills, billet mills, beam
and shape steel mills, and
especiallu for the rolls with deep
grooves and roughing stands of hot
strip mills. |
