STATIC CASTING |
The Foundry is equipped
with modern facilities for preparing
moulds to exacting standards. All rolls
are bottom poured with tangential ingate
to ensure maximum cleanliness of the
body surface. All nodular iron rolls are
poured with special ladle inoculation
followed by mould inoculation to ensure
high strength requirements. Hot Topping
equipment is used for all steel and
steel base rolls to ensure internal
soundness, grain size and structure,
making the rolls absolutely free from
cavities and porosities.

| SPIN
CASTING |
| Horizontal spin casting
machine is used to produce Work Rolls
for flat rolling.Spin cast rolls ranging
from 450 mm. to 1200 mm. in diameter are
produces through this machine with
strict control of rotation speed,
Cooling and casting time. The shell
sleeve is titled to vertical position
and core metal is poured from top with
precise thermal synchronisation to
achieve a perfect bond between shell and
core. High Core strength is achieved
through mould inoculation. |
