| Introduction
For the past 30 years Bharat Aluminium Company has been dedicated
to developing World Class Quality aluminium plates and sheets
of the various alloys. To stay ahead of the competition it
has adopted state of the art technology and has firmly established
itself as a front-runner among the producers of aluminium
sheets and plates.
Past Successes:
Since 1980 BALCO has been catering to the needs of Defence and Space
Research. The following sophisticated alloys have been developed
and supplied for defence and space applications:
| S.NO. |
Alloy |
Applications |
| 1 |
AFNOR 7020 |
Rocket fuel storage tank for ISRO |
| 2 |
AA 2219 |
Cryogenic applications for VSSC, Trivandram. |
| 3 |
DTD 5124 |
Ammunition hardware for O.F., Ambajhari. |
| 4 |
DTD 5024 |
Weldable secondary structural Components for O.F., Ambajhari |
90% of the aluminium alloys used in the ‘Agni’,
‘Prithvi’ and ‘Akaash’ missiles, which
have been test fired successfully, were supplied by BALCO.
State of the art technology available
with BALCO
CAST HOUSE:
- Properzi continuous rod casters
- Twin Roll Continuous Caster along with SNIF degasser (Maximum coil weight 10 tons, width 1750mm maximum)
- Hydraulically driven semi – continuous ingot Casting
machine.
SHEET ROLLING SHOP:
| Hot Rolling Mill: |
- This is the only 4 - High
Hot Rolling Mill in India.The
HRM
of BALCO has the capacity to roll the widest
slab (up to 1560 mm) plates among all the HRM installed
in India.
- The HRM contains a vertical rolling stand for edge
rolling of
the plates, which minimize edge cracking.
|
|
| Old Cold Rolling Mill |
BALCO has a 4 - High reversible rolling mill
which neither
Hindalco nor Indal has. The 4 - High mill helps
to
minimize shape variation in sheets.
|
|
| New Cold Rolling Mill |
The salient features of the new Cold Rolling Mill installed
are given below:
- Hydraulic automatic gauge control.
- Shapes and flatness control.
- Quick roll changing system.
- Computerised controls with process sequence controls.
