PLANT FACILITIES |
Process |
Hot Rolled (HR Coils) are received, by road from Integrated Steel Plants (Bokaro Steel Plant). Coils are sent thro’ Pickling & Rinsing Line and Cold Rolling for cleaner finish and achieving precise |
thickness for further
processing. Cold Rolled strips are
then sent thro’ annealing under inert
atmosphere. The Bright Annealing
Furnace has been supplied by
Technotherma India Pvt. Ltd.
Annealing temperatures vary
between 640 - 710
o
C depending
upon the carbon content of the coil.
Annealed strips are then sent to
slitting unit to achieve exact width
for final processing. Slits are then
finally processed in the Tube making
Unit by forming, induction welding
and sizing stages. Tubes are then
cut by a cold shear and are bundled
for dispatch to consuming industries. |
