Tata Steel
Today
As a result of innovations and technological upgradation,
Tata Steel, has become a well-run ultra modern plant - one
of the best in the world. Fundamental changes in some metallurgical
parameters have brought about this remarkable transformation.
Necessity became the mother of invention and numerous innovations
invoked improvement. The metallurgical changes introduced
were essentially centered around:
-
Reducing alumina level in sinter from 4.4 to 2.5 %.
-
Improving in coke quality
-
Making changes in the fluxes used in sintermaking essentially
to decrease the alkali input.
-
Adopting the optimum LD vessel configuration and blowing
conditions to accommodate the high slag volume required
to deal with high silicon and phosphorus in Indian hot
metal.
-
Increasing the yield during LD steelmaking
-
Introducing continuous casting (CC) instead of ingot
casting to increase the net yield.
All these factors have made Tata Steel internationally cost
competitive. In terms of hot metal costs, Tata Steel is amongst
the lowest in the world and has a clear advantage over other
major integrated producers. The cost of conversion from hot
metal to a finished product such as hot rolled coils where
Tata Steel has not been very competitive so far would be taken
care of in the near future as investments already made to
achieve the results foreseen. High ash in coke, poor room
temperature and high temperature strengths of coke, high alumina
in the iron oxide feed, high silicon in hot metal, low yields
during steelmaking, low yield of finished products, high energy
consumption, high manpower, etc. have been the weaknesses
not only of Tata Steel but of the Indian Steel industry as
a whole.
Appropriate steps taken by the Company have already resulted
in better yield lower energy consumption, lower silicon in
hot metal, lower silicon in hot metal, lower lime consumption
in steelmaking, higher vessel life, etc., all of which augur
well for the Steel Company in future.
Tata Steel in The New Millennium
Tata Steel is all set to establish itself as the supplier
of choice by delighting all its customers with its products
and services. The Organisation is envisaged to become the
most cost competitive Steel plant to serve the community and
the nation. Where Tata Steel would venture, others will follow.
The 21st century will certainly see a new Tata Steel - an
integrated Steel plant in India with truly world class facilities
along with a will to win amongst a committed and streamlined
workforce.
