Equipped with advanced Hydraulic Automatic Gauge Control (HAGC), online Gamma Thickness Gauge and L-2

Automation, Essar Steel can supply steel plates as per actual thickness, width, length and profiles, required for

specific projects or applications.

½ ASTM:

L-2 automation with no manual intervention and a walking beam furnace with a powerful de-scaler ensures that the

steel plates are precision manufactured to be supplied with consistency and maintains ½ ASTM tolerances.

Product Range:

Essar Steel offers one of the widest ranges of plate qualities, sizes and grades available anywhere in the world.

Leeds Compatible Process:

The Essar Steel plate mill has the capability to produce and supply plates that complies with LEED material

requirement. This is specific for any project that requires LEED compliance as a prerequisite condition for the usage

of plates.

E S S A R S T E E L

Essar Steel is a global steel producer with a strong presence in intensive steel consuming markets like Asia and

North America. Its goal is to reach a global production capacity of 20 – 25 million tonnes per annum (MTPA) by

augmenting its current capacity of 14 MTPA. Essar Steel is a fully-integrated operation from mining to retail, with

strong downstream capability and a worldwide network of processing and retail facilities, and distribution outlets

known as Hypermarts.

Global Operations

Essar Steel Algoma in Canada has a current capacity of 4 MTPA. Essar Steel Minnesota, USA (with iron ore

reserves of over 1.4 billion tonnes) – is developing a 7 MTPA pellet plant and an ore concentration plant. In

Indonesia, Essar Steel is the largest private steel processor and operates a 400,000 tonnes per annum (TPA)

cold rolling complex with a galvanising line of 150,000 TPA.

Essar Steel is the largest steel producer in western India, with a capacity of 10 MTPA at Hazira, Gujarat. The steel

plant is backed by an iron ore beneficiation and a pelletization unit that ensures supply of quality raw material.

The Essar Steel complex at Hazira has a complete infrastructure setup including a captive port, and power, lime

and oxygen plants.

It has set up a 1.5 MTPA plate mill and a 0.6 MTPA pipe mill at Hazira to make further value-additions to its

product portfolio. Essar Steel has the country’s largest steel processing capacity of 4 MTPA at its seven

processing and distribution facilities, located at key automotive and industrial hubs. In India, it has the distinction

of being one of the largest galvanisers, as well as being the largest producer of cold rolled and colour coated

products. Additionally, a 6 MTPA pellet plant is located at Paradip, Orissa and will be increased to 12 MTPA by

the next financial year.

The Thermo-Mechanical Control Process (TMCP)

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.

Process for producing heavy plates

Concept of microstructure change during TMCP

Advantages

- Superior weldability due to lower carbon

equivalent (Ceq)

- Better formability

- Excellent mechanical properties (high strength and

toughness) attained through fine microstructure

- Shorter processing time as no heat treatment is

required

Normalising

The process of producing a stable microstructure by

heating it to the high temperature austenite and

slowly cooling it.

Advantages

- Refines and ensures homogenous structure

- Reduces residual stresses from rolling

- Reduces the risk of "banding”

Quenching and Tempering

This is a conventional process used to harden or

strengthen steel. During quenching, 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.

Advantages

- Increases hardness for better wear and abrasion

resistance

- Improves ductility and toughness

- Reduces cracking

- Increases impact resistance

WORLD CLASS PLATE MILL FACILITIESRolling Mill

High roll separating force of 10,000 tonnes, almost double compared to some of the other plate mills - generates

extremely fine grain properties on plates. The mill is supported by a fully automatic gauge controller, plan view rolling

and flatness gauge to achieve a high degree of profile, even for very thick plates.

Thermo-Mechanical Controlled Rolling (TMCR) and Accelerated Direct Cooling (ADCO)

Thermo mechanical rolling and DQ (direct quenching) equipped with ADCO facility for high strength plates - can be

used in demanding applications for the oil & gas sector and other segments.

Hot Leveller

A leveling force of 4000 tonnes, generates excellent flatness, zero distortion and an optimally adjusted even surface.

The rollers flatten plates up to 1/2 ASTM tolerance.

Shearing Units

Equipped with different types of mechanical shears such as crop shears, double side cut shears, slitting shears and

dividing shears, the Essar Steel plates can be customized to size and widths as specified by the customer. Mechanical

cutting as opposed to burning also leads to lesser heat treated zones and better utilization and yield.

Heat Treatment

Heat treatment facility with austentising, normalizing, quenching and tempering to provide desired properties of steel

plates. Furnace normalization is done in an inert atmosphere with indirect radiant type heating to ensure no scales are

formed on the surface of the plates, leading to a better yield. Quenched & Tempered facilities spray the plates with

more than 10,000 cubic metres of water in two minutes.

Ultrasonic Testing

100% ultrasonic testing is performed for plates up to 50 mm thickness using an image comparator and without any

manual intervention. To keep it perfectly aligned the testing unit is recalibrated every day. Testing of plates above

60mm thickness is done manually by an international third party inspection agency.

Marking and Traceability

All plates produced at Essar Steel are marked with unique identification mark for traceability using paint marking,

mechanical stamping and bar coding.

High-tech plate mill features with world class processes and ultra modern facilities:

• 10,000 tonnes of roll separating force

• Thermo Mechanical Controlled Process with Accelerated Direct Cooling

• 4,000 tonnes of hot leveller capacity

• 100% online ultrasonic testing

• Furnace normalised, quenching & tempering furnaces

• 1100 to 4950 mm width

• 5 to 150 mm thickness

The Essar steel plate mill is amongst the finest in the world with one of the widest ranges of plates of excellent

strength, durability and shape properties.

State-of the-art Technology

Digital Reheating Furnaces

Equipped with side burners and split into different control zones for uniform heat transfer. The digital furnaces

eliminate hot spots and reduce excess scale formation on slab.

LEEDs Compatible Steel

One of the few Indian Steel companies to be LEEDs compatible, Essar Steel produces the greenest plates as

compared to other steel plants as the entire Hazira complex with includes HBI unit, HSM unit and Plate mill are

all LEEDs certified.

Application engineering

Application engineering and product development in Essar Steel is the corner stone of the successful

integration of deep insight and understanding of the customer’s current and evolving needs with a meaningful

product development solution. The new product development efforts of the application engineering team

delivers sustained value-creation for customers right from conceptual design to ready for service value

Properties Required During Service

Generally, steel plates are hot / cold formed to desired shape for major boilers to withstand high temperature, pressure and adverse corrosive environments. Since boilers and pressure vessels carry high pressure and temperature fluids and hold low- temperature fluids, the

steel plates are required to have high strength, toughness, ductility and corrosion resistance. Due to high temperature applications, the steel plates should have excellent creep resistant properties.

Mechanical Properties- High strength- Good low-temperature toughness- High corrosion resistance, high resistance to HIC,

SSCC and embrittlement- High creep resistance

– wave loading, sea slap and slamming thermal

excursions in tropical and arctic seas, vibration and

cargo buoyancy. Thus, steel plates require high
