Chapter-3PROFILE OF
VISAKHAPATNAM STEEL PLANT
3.1 BACKGROUND
The government of India was for long deliberating to set up an integrated
steel in the southern part of the country. After lot of study and planning
Visakhapatnam shore based town was selected for the same. Selection committee
chose the site close to the Balacheruvu creek and the Prime Minister did the formal
inauguration on 20th January 1971.
The consultant M/s M.N. Dastur and Co., Ltd submitted a detailed project
report (DPR) for the plant with an annual capacity of 3 million of liquid steel in
October 1977.
The Russians examined the DPR prepared by Dastur and offered Economic
and Technical co-operation for the same followed by an agreement signed with
erstwhile USSR on June 12th 1979 for co-operation in setting up 3.4 MT integrated
steel plant at Visakhapatnam. A Comprehensive Revised DPR (CRDPR) was
revised by Soviet and Indian design organisation in 1980.
The project was estimated to cost Rs. 3897.28 crores based on prices as on
4th quarter of 1981. However on completion of construction and commissioning of
the whole plant in 1992 the cost is estimated to be Rs. 8,755 crores based on
prices as on 2nd quarter of 1994. Unlike other integrated steel plants in India
Visakhapatnam Steel Plant is one of the most modern steel plants in the country.
New technology, large-scale computerisation and automation etc., are incorporated
in the plant. To operate the plant at international levels and attain such labour
productivity, the total manning of the organisation has been limited to 17500
employees. The plant has a capacity of producing 3.0 MT of Liquid steel and 2.656
MT saleable steel.

3.2 THE MAJOR PRODUCTION FACILITIES OF VSP
3.2.1RAW MATERIALS HANDLING
Some of the major raw materials required for the making of iron and steel
are iron ore lumps and fines, coking coal, limestone, manganese and dolomite.
VSP’s requirements are met by various mines located in the states of Madhya
Pradesh, Rajasthan, Orissa and Andhra Pradesh. VSP has its own captive mines
at Jaggayyapeta and Madharam in Andhra Pradesh for limestone and Dolomite
respectively. BF dolomite is obtained from Dubai and coking coal is imported from
Australia.
3.2.2COKE OVENS & COAL CHEMICAL PLANT
24
Coking coal after selective crushing and proper blending is subjected to
destructive distillation (heating in the absence of air) in the Coke Ovens. After
heating for nearly a period of 16-18 hours at a temperature of about 1100o C, coke
is obtained and is used as a fuel as well as reducing agent in the Blast Furnace.
The Coke Ovens of VSP are engineering feats by themselves. They are the tallest
ovens metre constructed in the country. The Plant has 3 batteries, which are 7
metres tall. Each battery consists of 67 ovens. Another feature is the dry cooling of
coke carried out by the inert gas nitrogen thus, reducing pollution considerably.
Besides a bio-chemical plant separately undertakes the treatment of effluents. By-
products like benzene, toluene, xylene, naphthalene, coal tar, creosote oil, pitch,
ammonium sulphate and benzol products are also recovered from the coke ovens
gas. VSP produces, among other by-products, “Pushkala” a prime fertilizer based
on ammonium sulphate.
3.2.3 SINTER PLANT
Iron ore fines, coke breeze, limestone and dolomite along with recycled
metallurgical wastes are converted into agglomerated mass at the Sinter Plant,
which forms 80% of iron bearing charge in the Blast Furnace. The Sinter Plant
comprises of two sinter machines each having 312 square metres of grate area
with a total production capacity of 5.256 million tonnes per annum.
3.2.4BLAST FURNACE
VSP has two Blast Furnaces with an effective volume of 3200 m3. each of
which are the largest in the country. Blast Furnace is charged with coke, iron ore
and sinter from the top and produces about 5000 tonnes of molten iron per day. Its
novel circular cast house with four tap holes ensures continuous tapping of hot
25
metal. The annual production capacity of these Blast Furnaces is 3.4 million tonnes
of liquid iron.
3.2.5STEEL MELT SHOP & CONTINUOUS CASTING
Three Top-blown converters, each of 133m3 volume, produce a total of 2.7
million tonnes of liquid steel per annum. This liquid steel thus produced is cast in
six-4 strand bloom casters. A special feature in energy conservation is the
collection of Converter gas to be used as a fuel in the plant. The entire molten steel
at VSP is continuously cast at the radial type continuous casting machines resulting
in significant energy conservation and better quality steel. 100% Continuous casting
on such a large scale has been conceived for the first time in India.
3.2.6 ROLLING MILLS
The cast blooms from continuous casting department are treated and rolled
into various long products of different specifications at 3 high capacity continuous
rolling mills. They are:
(a) Light & Medium Merchant Mill: - The mill consists of a Billet Mill
capable of rolling 1,915,000 tonnes of 250 mm x 320 mm blooms into
1,857,000 tonnes of 125 mm x 125 mm billets and a bar mill designed to roll
7,26,000 tonnes of billets to 710,000 tonnes of finished light merchant
products like rounds, rebars, squares, equal and unequal angles, flats, T-
bars and channels.
(b) Wire rod mill: - This is equipped with Morgan blocks and Stelmor
technology having a capacity of 850,000 tonnes per annum utilizing the

3.2.7 THERMAL POWER PLANT
A captive power plant, which can generate a total of 287 MW of power
produces power from fuels like coal, waste gases and oil. This can meet the total
power requirement of the steel plant, and even export about 50 MW power to the
state power grid.
3.2.8WATER SUPPLY
Requirements of water during the peak construction were of the order of 4.5
mgd. This was met from the Meghadrigedda and Raiwada schemes of AP State
Government. Operational water requirements 36 mgd, is being met from the Yeluru
water supply scheme provided by the AP State Government. This involved

3.6 THE TECHNOLOGICAL PROCESS IN VSP
The raw material iron ore in itself does not hold any value for the mankind.
However once it gets converted into iron, through metallurgical reduction process, it
holds a vast potential for use as a versatile metal. It is this basic process that is
taking place in an integrated steel plant like VSP, which is explained in brief here.
Raw Material Handling Plant receives all the input process raw materials like
iron ore lumps and fines, coking and non-coking coal, limestone, dolomite, etc.,,
through railway wagons. The raw materials are prepared to the process
requirement of size & specifications using crushers, screeners and different types
of stacking and reclaiming machinery. Coking coal is converted into metallurgical
coke at 'Coke Ovens' (CO). Coke is used as the essential raw material in iron
making. During the conversion, saleable by-products like Ammonium Soleplate,
Benzyl, Tar, and Naphthalene are extracted from the flue gases generated in Coke
Ovens, at 'Coal Chemical Plant' (CCP).
At the Sinter Plant iron ore fines are agglomerated by partial heating into
lumps (called sinter) along with other essential additives & coke fines, for charging
into the Blast Furnace for the iron reduction process. Sinter, Coke and Limestone
charged from the top of the Blast furnace (BF) gradually descends to the bottom in
the hot outgoing gases. The liquid iron and slag (silicon impurities) get collected in
the bottom and get separated from one another, the slag being lighter.
29
Both iron and slag are tapped and the slag is diverted and converted into
granules at slag granulation plant, as a value addition process to the slag, which is
used as input to brick and cement industries. Iron is collected in hot metal ladles
and sent to either pig casting machines or de-sulphurised to remove excess sulphur
and is sent to Steel Melt Shop (SMS). At SMS the iron is transformed into Steel
in LD Converters, by blowing high pressure oxygen gas through molten iron bath.
This iron refining process achieves the oxidation and removal of carbon, suplhur
and other impurities. Further purity is achieved by argon rinsing process. This
steel is cast into bloom in continuous bloom casting machines.
The Blooms from SMS are subjected to the process of re-heating and rolling
into saleable steel finished products, at Rolling Mills. There are three Mills at VSP,
to produce various finished products, namely: Light and Medium Merchant Mills
(LMMM): For producing billets, bars, angles and channels. Wire Rod Mill (WRM):
Wire rod of 6 to 12 mm thickness is produced. Medium Merchant and Structural
Mills (MMSM): Structural products like beams, large angles, I-sections, channels,
etc. are produced. At every stage, the above process is supported by other
essential inputs like electricity for driving the machinery, water for process and
cooling and the most essential input, the human resource or the manpower.
Converted in terms of a common unit of power, of all the process power inputs put
together, comes to around 6.62 Giga Calories for each ton of liquid steel produced.
With this one can well appreciate the technological process going on at a gigantic
scale, in an 'Integrated Steel Plant'.
Through all the above technological process, the growth in the value of the
basic iron ore grows a hundred folds, as it reaches its final stage, in the form
finished steel product. The process chart depicted at Figure : 3.1

sectors. The township is having best facilities in terms of drinking water supply,
drainage system, roads, community centres, crèche, parks, schools, shopping
complexes, medical facilities, recreational facilities, etc to cater to the needs of the
employees and their dependent families. The Company also provides welfare
facilities much beyond the statutory requirements by way of introduction of a unique
superannuation benefit fund and a unique family benefit scheme.
3.12 PRODUCTION PERFORMANCE
It is the story of performance scaling new heights at Vizag Steel by
surpassing all records be it in production, marketing, profitability, human
endeavour. Registering a record turnover of Rs. 6,174 Crores as shown in Fig-3.2
with a growth of 22% over last year. The company is poised to make a provisional
gross margin of Rs. 2023 Crores, cash profit of Rs. 1972 crores and a net profit of
about 1,521 crores as shown in Fig-3.3, the best financial performance since
inception. Interest was contained to about Rs. 50 Crores. Vizag Steel’s habit of
putting continuous thrust on new processes and newer technologies enabled it to
consistently perform beyond rated capacities. Today the plant is operating at a
capacity utilisation ranging from 110% to 120% across various production units.
Vizag Steel’s continuous efforts towards energy conservation, cost reduction and
waste utilisation were mainly instrumental in placing Visakhapatnam Steel Plant
among the lowest cost steel producers in the world.
35
It is needless to say that Human Resources is the prime factor for these high
performance levels attained and subsequent turnaround of Vizag Steel. Vizag
Steel’s continued thrust on total employee involvement across all levels has
contributed immensely for healthier IR scenario which in-turn led to zero man day
loss and today Vizag Steel has highest Labour Productivity of 262 tons/man year as
shown in Fig-3.4, the best amongst the Indian integrated steel plants.
During the year under review, VSP has sold 2.82 MT in domestic market and
0.38 MT in export market. To facilitate availability of material in domestic market,
VSP had reduced its exports by 9% over previous year. However, the price
increases and appreciation of rupee had resulted in export revenue earning by 28%
over previous year. The domestic sales turnover has also increased by 22% with
Rs. 5406 Crores. Creation of distinctive trend brand image and good customer
relationship management, will all efforts to give customer the value for money, are
always main concern at Visakhapatnam Steel Plant. As a result, customer
satisfaction is the main and foremost gain for Visakhapatnam Steel Plant today.
“VIZAG TMT” the brand name of Vizag Steel re-bars commands highest premium
in the market today.
During financial year 2003-04, the company has produced 4.05 MT of Hot
metal, 3.51 MT of liquid steel as shown in Fig-3.5, and 3.17 MT of Saleable steel as
shown in Fig-3.6, the best yearly performances since inception. After surpassing
the rated capacities consecutively for the last 3 years, Visakhapatnam Steel Plant
set its aim to utilise inherent untapped potential by making needful investments in
different areas to produce growth oriented products. Emphasis is also being given
on various AMR schemes with an objective to improve the quality of the products
36
as well as to reduce costs. The company’s focus is on widening its product-mix
and stabilization of special steels production. During the current year, over 8.0
Lakh tons of special steels were produced as shown in Fig-3.7, which is about 1/4 th
of the total saleable steel. With this excellent performance for this financial year,
Visakhapatnam Steel Plant has made its make in international steel scenario. The
task for the future is to overcome the present constraints and chalk out the
necessary infrastructure development.
For the present, the immediate concerns for Visakhapatnam Steel Plant are
the non-availability of raw materials and the abnormal price rises of input materials.
With the increased production particularly in China and temporary closure of some
of the coal mines in Australia, there is a shortage of coal and coke all across the
global and Visakhapatnam Steel Plant is no exception. To tide over the present
crisis, VSP is putting all its efforts to source raw materials both from indigenous and
imported sources and is hopeful to get the required quantity for maintaining its
normal production levels. For the long term, VSP has set its aim to acquire Iron
Ore and Coal Mines and requested Ministry of Steel to take up with the concerned
Ministries and also exporting the possibility of joint venture to own some of the
coalmines abroad. With the immediate necessities being taken care of, the long-
term plans being pursued as per time schedule, Visakhapatnam Steel Plant is
determined to march-forward with improved performance year after year.
3.13 ISO CERTIFICATION IN VSP
37
Standardisation of any process leads towards the desirable results of the
process. It tends to cut down on the wastage of energy and resources and
minimises process output defects and rejects. Adherence to standards also
increases the process and personnel safety aspects. It now follows as a logical
sequence that every organisation to achieve organisational objectives must have
technological and administrative norms laid down. VSP with its foresight has
envisaged the need to compete in the domestic and international markets and the
inherent need to be associated with 'International Standards Organisation' (ISO).
VSP has become the industry leader by becoming the first ever steel plant to have
obtained 'ISO-9001' for 'Quality Systems' for all of its processes, in April' 2000. It
has already geared its documentation and records to measure up to the
rationalised 'ISO-9000:2000' certification for 'Quality Management Systems'.
In October 2001 VSP has become one among the very few steel plants in
the world to be awarded the prestigious ISO 14001 Certificate by BVQI, London for
its Environmental Management System and in April 2002 VSP has been awarded
OHSAS 18001:1999 Certification for its Occupational Health and Safety
Management System by BVQI, London. With these certifications VSP has earned
the status of being the only integrated steel plant in the country accredited with 3
standards ISO:9001, ISO:14001, and OHSAS:18001. With these new technologies,
automation, along with commitment towards continuous growth and customer
satisfaction, and equipment comparable to the best in the world and introduced for
the first time in the country, Visakhapatnam Steel Plant is set to achieve market
leadership in the steel sector.
