1.0 INTRODUCTION

1.1 PREAMBLE:

Ferro-alloys are among the essential inputs required for steelmaking. It improves the

quality of steel, by controlling the harmful impurities and at the same time improves the

mechanical properties of steel through alloying. Growth in Global as well as domestic

steel industry directly drives the demand of Ferro-alloys. Since Indian steel industry is

under massive expansion, there is a tremendous potential for investment in Ferro-alloy

production.

Steel being a basic commodity for all industrial activities, quantum of its consumption is

considered an index of industrial prosperity. Since independence, there has been a

substantial growth in the steel sector in India from 1.5 Million Tons in 1950-51 to about

31 Million Tons at present. Additional steelmaking capacity of about 8 to 10 Million Tons

/year exists in the secondary steel sector. Despite the above growth in the steel sector,

the per capita steel consumption continues to remain at a level of about 27 kg only,

compared to about 350 to 450 kg in the developed countries and 40 to 100 kg in some

of the developing countries. Further, with nearly 20% of the world population, India’s

contribution is only of the order of 3.4% of world steel production. Hence, short-term

and long-term strategies are necessary in planning the development of the steel

industry in the country to improve the level of per capita steel consumption. It is

expected that with the measures taken by Govt. of India for promotion consumption of

iron and steel and expected growth of Indian economy the requirement of steel will

significantly increase and accordingly the domestic manufacturing capacity needs to be

increase.

The specification covers the design, manufacture, shop testing, supply, erection and of

Steel Melt Shop (SMS) Equipment, i.e., Electric Arc Furnace (EAF), Ladle Refining Furnace

(LRF), called Ladle Furnace (LF), and Continuous Casting Machine (CCM) for 400,000 TPA

2.3 NEED FOR THE PROJECT AND IMPORTANCE TO THE REGION:

2.3.1 GLOBAL STEEL SCENARIO

Global steel production grew enormously in the 20th century from a mere 28 million

tons at the beginning of the century to 1011 million tonnes at the end of 2005. That was

the period when the steel industry developed in Western Europe and the USA followed

by the Soviet Union, Eastern Europe and Japan. However, steel consumption in the

developed countries has reached a high stable level and growth has tapered off.

Towards the end of the last century, growth of steel production was in the developing

countries such as China, South Korea, Brazil and India. Steel production and

consumption grew steadily in China in the initial years but later it picked up momentum


17

China produced 220.1 million tons in 2003, 272.2 million tons in 2004 and 349.36 million

tons in 2005. That is much above the production of Japan at 112.47 million tonnes, the

USA at 93.90 million tons, Russia at 66.15 million tones and India around 42 million tons

in 2005.

2.3.2 STEEL PRODUCTION IN INDIA

India is one of the few countries where the steel industry is poised for rapid growth.

India's share in world production of crude steel increased from 1.5% in 1981 to around

3.5 % in 2004. While plant closures and privatization are rare in India, the private sector

is considered to be the engine of growth in the steel industry and technological changes

and modernization are taking place in both the public and the private sector integrated

steel plants in India. Steel production of India accounted for 14.33 million tons in 1990-

91, which gradually increased to 36.12 million tons in 2003-04, as shown in Table below.

The Indian steel industry got a giant importance in the recent past when the Tata Steel

purchased the Corus steel. Today India plays a significant role in the production of steel

in the world. The Indian steel industry is growing at 8.74 % of CAGR.

2.3.3 STEEL BIILET INDUSTRY

Steel billets are manufactured either by ingot casting and rolling through blooming &

billet mills or by forging or by continuous-casting of billets directly from liquid steel.

Billets manufactured by forging are mostly alloy or special steels. Pencil ingots of smaller

sizes, manufactured in mini steel plants are also used as substitute of billets. Due to

better yield, less energy consumption and capital investment, continuous-casting is

being practiced even for production levels of 25,000-30,000 TPA of billets. The billet

being a semi-finished product is used for further processing for production of suitable

products. It is used as a feedstock to rolling mills for production of long products like

wire rods, bars/rods and light structural. Billet is also used extensively in forge shops

and machine shops for production of engineering goods and also as feedstock for

seamless tubes.


18

While projecting all-India demand for steel billets, the requirement of the same for

integrated steel plants (primary producers) has not been considered, since their captive

requirement goes for finished steel production. The anticipated production of mild steel

bars and rods and structural from secondary producers during 2006-07 is of the order of

11.8 million tons. Billet requirement for producing the above products will be around

12.5 million tons. The production of pencil ingots/billets from secondary sector during

2006-07 is likely to be about 10 million tons, which includes mild steel, medium/high

carbon steel, alloy steels etc.

In view of the above, demand for steel billets excluding the captive requirement of

integrated steel plants is mainly dependent on production levels of bars and rods and

structural by secondary producers.

EMPLOYMENT GENERATION (DIRECT & INDIRECT)

The proposed expansion project creates employment to 570 people. The total no. of the

people after expansion will be 965.

3.2 PROCESS DETAILS:

• EXPANSION OF EXISTING SPONGE IRON PLANT CAPACITY FROM

60000 TPA TO 2,91,000 TPA BY INSTALLING 2 X 350 TPD ROTARY

KILNS AND OTHER ANCILLIARY UNITS

The proponent has decided to enhance the capacity of existing Sponge Iron Plant from

60,000 TPA to 291000TPA by installing additional 2 X 350 TPD Rotary Kilns for

production of 231000TPA Sponge Iron. The char produced from the rotary kiln will be

used in power plant.


20

Waste Heat Recovery Boilers will be installed for flue gas heat recovery of 2 x 48 Tons/hr

Steam generation capacity. The steam so generated from these new Waste Heat

Recovery Boilers (WHRB’s) will be sent to the existing 30 or 35 MW Power Plant turbines

(by providing a new steam pipeline) and one of the existing fossil fuel based

Atmospheric Fluidized Bed Combustion Boilers (AFBC Boiler) of 70 or 80 TPH capacity

will be shutdown. This will not only save the fuel costs incurred in the existing Power

Plants but will also contribute positively by reducing the green house effects and other

environmental hazards caused due to combustion of the fossil fuels.

• FERRO ALLOYS PLANT OF 50000 TPA CAPACITY.

A) SUBMERGED ARC FURNACES (SAF)

Submerged Arc Furnaces (SAF) is the heart of Ferro-alloy plant wherein oxides of

manganese, silicon, iron, phosphorous etc contained in feed ore are reduced by coke/

carbon. These SAFs are located inside the Ferro Alloys Plant.

B) SINTER PLANT FOR MANGANESE ORE FINES:

A sinter Plant will be installed for production of sinter feed material of Manganese

Ore to the Ferro Alloys Submerged Arc Furnaces by using the Manganese Ore fines

available nearby.

• ELECTRIC ARC FURNACE / LRF / VD / AOD BASED ALLOY STEEL BILLET

PLANT OF 4 LAC TPA CAPACITY

In Electric Arc Furnace recycled steel scrap and DRI is melted and converted into high

quality steel by using high power electric Arcs. Modern EAF is a tool to convert solid raw

materials such as Steel Scrap and Sponge Iron into liquid crude steel as fast as possible

and then refine further in secondary steel refining processes such as Ladle Refining

Furnaces, Argon Oxygen Decarburization(AOD) and Vacuum Degassing (VD) Units.


21

The Electric Arc furnace consists of a circular bath with a moveable roof, through which

three graphite electrodes can be raised or lowered.

At the start of the process, the electrodes are withdrawn and the roof swung clear. The

steel scrap is then charges into the furnace from a large steel basket lowered from an

overhead crane.

When charging is complete, the roof is swung back into position and the electrodes are

lowered into the furnace. A powerful electric current is passed through the charge, an

arc is created and the heat generated melts the scrap. Sponge Iron is continuously

charged to the liquid metal pool to get the required size of the liquid metal heat. Lime

and fluorspar are added as fluxes, and usually carbon and oxygen are blown into the

melt. As a result, impurities in the metal combine to from a liquid slag.

Samples of the steel are taken and analyzed to check composition and, when the correct

composition and temperature have been achieved, the furnace is tapped rapidly into a

ladle. Final adjustments to customer specification can be made by adding alloys during

tapping or later in a secondary Steelmaking unit.

Refining the Liquid Steel

The Liquid Steel from the EAF is tapped into a pre heated ladle. The ladle is taken to

Ladle Refining Furnace for carrying out refining operations. The ladle is fitted with

porous plug and an inert gas is purged through the steel bath during entire refining

operation. The steel is deoxidized and desulphurised by treating under basic reducing

slag which is rendered fluid by arc heating and also by adding fluorspar to it. For

making/ reducing & desulphurising slag, burnt lime, fluorspar, ferro-silicon and

powdered coke are normally added. The reducing slag reduces the oxides in the bath

and assists in the removal of sulphur as calcium sulphates. The desulphurization is also

promoted in presence of sufficient quantity of manganese in the bath, high basicity of

slag and high bath temperature. By blowing with the inert gas, the metal in the ladle is

stirred and as a result of purging its temperature and composition are equalized and


22

non- metallic inclusions would float up to the surface. Necessary ferro-alloys are added

to the liquid steel through a port on the ladle cover after the bath has been fully

deoxidized. A sample is, thereafter, drawn out and sent to the laboratory for final

analysis. Further arc power may be applied to increase the temperature to the desired

level, if necessary. As soon as the final analysis conforms to the desired composition

and proper temperature has been attained, the ready metal is transferred to vacuum

degasser.

Vacuum Degassing

A ladle of liquid is transferred by overhead crane from the LRF unit to the vacuum

degasser. The ladle is placed in a cylindrical tank and is supported inside the tank. The

tank is constructed with the steel plate and is lined with refractory.

When the ladle has been located in the tank and inert gas supply is connected to one or

more porous plugs located in the refractory lining in the bottom of the ladle. Inert gas is

blown through the plug at control rate to stir the liquid metal in the ladle and expose

the surface of the liquid steel by pushing aside the slag layer on the surface.

The tank equipped with a flange around the upper periphery of the tank side wall is

then sealed by a cover which is located in self-propelled car. The car drives over the tank

and then covered is lowered until the flange around the lower edge of the cover is

connected with the tank flange.

An “O” ring seal between the two flanges creates a vacuum tight seal. The volume

enclosed by the tank and the cover is then evacuated by a set of vacuum pumps

connected to the tank. As the pressure in the tank falls, the flow of inert gas through

porous plug in the bottom of the ladle can be adjusted to create the required degree of

turbulence in the ladle. The dissolved gases like hydrogen, oxygen etc are removed by

effusion from the surface of steel to the low negative pressure surrounding atmosphere.


23

Argon Oxygen Decarburization (AOD) Converter

Converter process of Argon Oxygen Decarburization (AOD) was introduced in early

1970s, andis now the preferred route for specialty electrical steel and stainless

steels.Secondary refining equipment mainly used in final refining step for stainless

production includesAOD furnace. Stainless steel contains a large amount of chromium

as a basic component.

Since chromium is a strong oxides forming element, during normal refining it is difficult

todecarburize stainless steel to a sufficiently low carbon level while preventing loss of

chromiumthrough oxidation to slag phase.Thus low carbon levels are achieved by

decreasing the partialpressure of carbon mono oxide in the refining atmosphere to

ensure preferential decarburizationin the presence of chromium.

In practice this is in done in AOD furnace by dilution with argon and in VOD furnace by

reducingthe pressure.The AOD Converter Plant shall be located near the furnace. The

Steel scrap/DRI will be melteddown in the Furnaces. The molten metal at temperature

of 1600°-1650°C will be transferred tothe AOD Converter Vessel via overhead crane to

refine to the desired chemical composition byaddition of required Alloys/Fluxes and use

of various gases.

The gases media such as Oxygen, Nitrogen, Argon& Compressed Air is injected into AOD

Converter through High Blowing rate Tuyers for good mixing effect and excellent heat

efficiency.

Continuous Casting of Billets

Liquid metal from VD / AOD or some from LRF directly is transferred to the continuous

casting machine for casting into billets.

The main operations involved in the whole process of turning out billets are:

i) Checking the individual major components of the casting machine and their

synchronized operation;


24

ii) Insertion of a dummy bar to close the bottom end of the mould;

iii) Accurate centering of the tundish over the mould;

iv) Transferring the ladle to the casting aisle and placing it on the ladle stand of the

casting machine;

v) Pouring of liquid steel from the ladle through a slide gate mechanism into the lined

tundish;

vi) Pouring of liquid steel into the water cooled mould through tundish;

vii) Passage of liquid steel through water cooled mould tubes initiated by withdrawing

dummy bar;

viii) Oscillation of the mould;

ix) Maintaining a constant level of liquid steel in the mould and introducing lubricants

into the mouldthroughout the casting process;

x) Controlling the intensity of cooling of the emerging billets in the primary and

secondary cooling areas; and

xi) Straightening and cutting of billets.

The most important component of a casting machine is the bottomless water cooled

copper mould. The internal shape and size of the mould tube is the same as that of the

cross section of the billet / blooms to be cast. To initiate casting, a dummy bar is

inserted to the bottom end of each mould, while the other end of the dummy bar is

held by withdrawal/ straightening rolls. Molten steel at the correct temperature is

poured into the mould and when it reaches the stipulated level, the withdrawal rolls,

mould reciprocation unit are operated; cooling water circulation through the mould and

in the secondary circuit is started few minutes earlier the actual casting operation is

started. The dummy bar is withdrawn, followed by hot solidified billet. The cooling

water circulating around the mould has carried away enough heat from the liquid steel

to produce a solid outer skin of sufficient strength to safely envelop the still liquid

portion at the interior that too will be solidified by a secondary cooling. The rates of

solidification and withdrawal are obviously inter linked. Before beginning to withdraw


25

the dummy bar it must be ensured that the outer casting of the billet is strong enough

for the process to continue. An error in this regard will cause “break out” of the strand,

which will then remain inoperative for the rest of that heat into casting. For obtaining

satisfactory surface quality of billets and for satisfactory performance in general, the

liquid steel temperature, casting speed, the rates of primary and secondary cooling

must be controlled and matched. Usually this harmonization is developed on the basis

of practice in the particular plant. If the casting speed is increased to raise output, the

quality of the central zone of the billet may suffer because of increase in unsoundness,

chemical heterogeneity and prone to internal cracking.

Billet Processing

The billets from a particular cast are lifted from the cooling bank and stored separately.

When cooled, they are inspected on each face for defects; surface defects are normally

removed by a swing frame grinder, etc. These billets will then be fed to the new Alloy

Steel/Wire Rods/TMT Bar Mill or the Light Section Mills for rolling into long products for

onward sale to the market.
