Heavy Plates
for Speciality
Applications
Widening horizons of the future
The demand for thicker, wider and ultra high strength steel plates has
been increasing due to rapid industrialisation across the world. Key
industry players across different segments in India, have concurred
that availability of thicker and wider width plates will result in enormous
savings on fabrication and welding, and also lead to an improvement in
yield, quality and durability.
Recognising the growing needs and potential of the plate market in India,
Essar Steel has recently commissioned a state-of-the-art plate mill at
Hazira. The 4 Hi Rolling mill has a roll separating force of 10,000 metric
tonnes and can produce plates with a width of up to 5 metres. Other facilities
include Normalising, Accelerated Cooling / Direct Quenching, Hot and Cold
Levelling and Quenching and Tempering.
Coupled with advanced steel-making facilities, the mill can produce plates
with extremely low sulphur content and tramp elements which guarantee
extremely high toughness values of up to -80°C. The special feature of
Accelerated Direct Cooling (ADCO) enables designing of products for
specific wear resistance applications.
Essar plates are supported by the best manufacturing practices and testing
facilities including the Scanning Electron Microscope with EDAX, to ensure
clean steel with low inclusion. Essar plates conform to all international
standards including API, ASTM, EN, JIS and IS. They are also supplied in
customised grades as per client-specific requirements.
Plates undergo close process metallurgy and chemistry that is
customised to the specific requirements of different application segments.
The Essar Steel mill is capable of producing high strength and high
toughness plates that can cater to niche segments with an optimised
thickness-to-strength ratio resulting in weight reduction.
Essar’s quenched and tempered plates are designed to meet the demands
of strength, toughness and wear resistance for specialised applications –
earth moving machinery, heavy earth movers, submarines, shipbuilding,
anti-ballistic plates and extremely low temperature storage tanks. The
normalised plates are produced using cutting-edge technology suitable for
critical use in nuclear reactors, hydrogen reactors, supercritical boilers and
high pressure vessels for oil and gas.
Each final plate has a unique identification mark that ensures proper
traceability right from the stage of heat making to the final product. The
port location of the plant gives Essar Steel a logistical advantage thereby
ensuring timely production and delivery of orders across the world.

Essar Plate Mill
World-class Processes, Ultra-modern Facilities
Digital Reheating Furnaces
With a capacity of 1.5 MTPA, the plate mill is equipped to
produce steel plates with widths of up to 5 metres. Superlative
toughness, excellent weldability and perfect flatness make
these plates comparable to the best in the world.
The digital furnaces are equipped with side burners having an
independent on / off control for each burner, thus helping to
reduce excess scale formation. The furnace is split into different
control zones for uniform heat transfer through homogeneous
heat elimination of hot spots.

Rolling Mill
The reversible rolling mill along with cross rolling facilities has a
roll separating force of 10,000 tonnes. This force helps in highshape factor rolling and thus reduces the internal discontinuities.
The rolling mill is supported by high-speed automatic gauge control
for accurate dimensions, plan view rolling for proper crosssection and shape, profile and flatness gauge for ensuring
premium quality in plates.

formability and better weldability. ADCO ensures controlled
cooling with edge masking facilities for achieving uniform
properties along the cross-section. It also has the capability of
direct quenching for achieving high strength and high hardness
grades. This process is used for producing high-tensile steel
plates with high toughness and good weldability for all major
structural applications.

Hot Leveller
Heat Treatment
The hot leveller, with a capacity of 4,000 tonnes, provides
excellent flatness and residual stress-free plates. A plastification
ratio of up to 80% can be offered depending on the tensile
strength and thickness. The unit has automatic gauge control
and shape system to ensure a high level of flatness.
The mill is equipped with heat treatment facility with
austentising and normalising, and quenching and tempering
furnaces for acheiving the desired texture of steel plates. The
plates are shot blasted and an inert atmosphere is maintained
in the furnaces with indirect radiant type heating to ensure that
no scales are formed on the surface of the plate.
Shearing Units
Marking and Traceability
The shearing units in the mill can cut plates of up to 50 mm
thick. The mill is equipped with heavy duty shearing units like
crop shear for cutting the improper shapes of as-rolled plates,
double side trim shear for cutting improper shapes into wider
sections, slitting shear for trimming and dividing shear for length
and width trimming.
In addition to a hot paint marker, a plate marker & stamper
are provided to mark or stamp each final plate with a unique
identification mark. This ensures proper traceability right from
the stage of heat making to the final product.
Logistics
Ultrasonic Testing
The ultrasonic testing unit is an on-line test equipment for
automatic inspection and evaluation of the full body of the
plates. A hundred probes ensure accurate examination of all
flaws. As a result, on-line inspection of up to 50 mm covering
100% of the plate body and edges is done. Indications are
recorded and evaluated to ensure precise monitoring of the
internal quality of heavy plates cut in the shear lines.
Essar has a captive port which can accommodate vessels of
up to 60,000 DWT, enabling Essar to ship customer orders
directly without multiple handling.

Metallurgy of Plate Rolling
The Thermo-Mechanical Control Process (TMCP)
• Shorter processing time as no heat treatment is required
Through TMCP, very fine and uniform ferrite microstructure
is obtained and results in higher strength and toughness.
The plate is also less susceptible to cold cracking and has
better weldability.
Normalising
The process of producing a stable microstructure by heating it
to the high temperature austenite and slowly cooling it.

Process for producing heavy plates
Quenching and Tempering
This is a conventional process used to harden or strengthen
steel. During the quenching step, the austenite is converted
to martensite. The quenched alloy is then tempered at an
intermediate temperature to transform the brittle martensite
into a very fine dispersion of cementite (iron carbide) phase in
an iron ferrite matrix.

Applications
Challenges During Usage
• Offshore structures
Plates for marine applications must endure adverse load
conditions like corrosion and large cyclical loads – wave
loading, sea slap and slamming thermal excursions in tropical
and arctic seas, vibration and cargo buoyancy. Thus, steel
plates require high strength coupled with good low-temperature
toughness, through thickness properties, corrosion and fatigue
resistance, and tight dimensional tolerances. One of the most
important requirements is toughness in the base plate and in
the HAZ regions.

Boilers and Pressure Vessels
Powering the future
Applications
Properties Required During Service
Boilers:
Generally, steel plates are hot / cold formed to desired shape
for major boilers to withstand high temperature and pressure,
and adverse corrosive environments. Since the boilers and
pressure vessels carry high pressure and temperature fluids,
hold low-temperature fluids, the steel plates are required to
have high strength, toughness and ductility, and corrosion
resistance. Due to high temperature applications, the steel
plates should have excellent creep resistant properties.
