CHAPTER – I

INTRODUCTION

Ferro Alloys are an important component added to Steel for enhancement of its

properties. Alloying elements such as Manganese (Mn), Silicon (Si), Chromium (Cr),

Molybdenum (Mo), Tungsten (W) etc. need to be added to Steel while it is still in molten

state to improve various physico-mechanical characteristics. These elements are

normally added to steel in the form of Ferro Alloys. Besides alloying functions, Ferro

Alloys are very essential for Steel making as it is used for deoxidizing and degassing.

Steels are mainly classified according to its alloying elements such as low alloy, medium

alloy and high alloy Steels.

Submerged Electric Arc Furnace route is being used for Ferro Alloy production since

1951. Though several types of Ferro Alloys are in vogue, the major Ferro Alloys are

Ferro Manganese, Silico Manganese, Ferro Silicon and Ferro Chrome. Production of

Ferro Alloys calls for availability of right type of ore and quality power at the optimum

parameters. India is fortunately endowed with good reserve of ores such as Mn Ore,

Chromite, Quartz, etc, which are suitable for Ferro Alloy production. As such, it is a right

place for ore based Ferro Alloys production. 97% of proven Chrome Ore reserves of

India occur in Sukinda Valley in Jajpur district of Orissa. Barjora is about 400 km from

Chrome ore mines and 250 km from Haldia port (for imports). Good quality power at very

competitive rates are supplied by Damodar Valley Corporation (Power utility) in this area.

Besides, the area has good infrastructural facilities and proximity to other minor

indigenous raw materials, making it an attractive location for a Ferro Alloy plant.

The technology for Ferro Alloy production is available indigenously and plants can be set

up by utilizing indigenous equipment, engineering and know-how.

The demand for Steel is increasing vis-a-vis production in India. Hence, the demand for

Ferro Alloys, which is a necessary addition, is bound to increase. Each tonne of Mild

Steel produced requires a minimum of 8-10 kg of Ferro Alloys. The corresponding

requirement for stainless steel are about 200 kg of ferro chrome and an almost equal

quantity of other ferro alloys.

The Ferro-Alloy industry is predominantly located in Andhra Pradesh, Orissa,

Chhattisgarh, West Bengal, Jharkhand & Meghalaya. There are more than 100 units in

India, with a total capacity of 4-5 million tonnes. Manufacturing of ferro alloys is a power-

intensive process.

CHAPTER – III

THE MARKETING ASPECTS

3.1 Increase in global steel production:

The global steel production has increased continuously over the last few years

and this trend is expected to continue in the years to come. The production of

crude steel for last few years and future production as projected is given below in

Table – 3.1:

Table – 3.1

Year Production of Steel (million tonnes)

2010 1394

2011 1491

2012 1510

2013 1578

2014 1636

2015 1596

2016 1625

2017 1711

As can be seen from the table above, the global crude steel output has been

growing at about 5% and is expected to grow at a similar rate overall. The steel

growth in India has been higher and is expected to grow @ 7% till 2030 by when

the production is expected to reach about 230 million tonne. This consistent

growth of crude steel production will have a direct correlation with the demand for

ferro alloys i.e. Ferro Chrome, Silico Manganese and Ferro Manganese

3.2 Change in Production Pattern of Steel i.e. its Mix:

Manganese-intensive steel accounts for 13% of the global steel production and

this proportion is expected to rise. Similarly, stainless steel (consuming high

quantities of ferro chrome) is rising due to demand of higher quality steel for both

industrial as well as domestic applications. The bulk of steel production

comprises multi-purpose low carbon steels containing only 0.15% to 0.80%

manganese while high strength steels with yield strength over 500 MPa contain


15

over 1% manganese but represent only 3 to 4% of the tonnage of the steel

produced today.

The latter leverage the austenitic transformation temperature to obtain a fine

ferrite structure. Micro-alloying additions reinforce the structure through carbide or

nitride precipitates which are evenly distributed in the ferrite matrix. These steels

are widely used for oil/gas pipelines, shipbuilding and in transportation equipment

to reduce weight without compromising strength.

Engineering steels comprise either HSLA or heat-treated grades; either pure

chromium-manganese grades, or with nickel, chromium, molybdenum, vanadium

additives and often 0.6 to 0.8% manganese. A few grades containing 1.0% to

1.5% manganese (as well as chromium or boron) are popular with the automobile

industry.

Stainless steels represent less than 2% of total world steel production and

contain about 1% manganese. Special manganese-stainless steels, where nickel

is replaced partly or entirely by manganese, have a manganese content of 4 to

16%. An example of the same is the series 200 stainless variety.

Any overview of high manganese steels must include Hadfield steel which

contains 13% or more manganese. Its unique properties make it indispensable

for applications requiring toughness and wear resistance. Among these can be

cited gyratory crushers, jaw-crusher plates, railway points and crossover

components, teeth for earth-moving equipment, etc. High manganese (10-12%)

non-magnetic steels are used for such products as retainer rings for turbo

alternators and collars on oil rigs. Grades with a similar chemistry are used as

cryogenic steels.


16

3.3 Demand for Ferro Alloys

Demand for Ferro Alloys is directly linked to steel production level. Looking at the

projection of demand for steel and ferro alloys it can be realized that there

remains a considerable gap between demand and supply of steel as well as ferro

alloys by 2020-11. To meet the demand, new capacities have to be created.

The production of ferro alloys is concentrated in a few pockets like India, China,

South Africa and the CIS. South African production has been hampered due to

logistics, power and political considerations. China is the biggest producer of ferro

alloys in the world but its government is discouraging exports due to the power

intensive nature of the product with an export duty of 20%. India enjoys a number

of advantages that make it a favourable location for global supply.

3.4 The Indian ferro alloy advantage

Low production cost: India has abundant supply of low cost manpower (skilled

and unskilled), which is an edge in a business that requires about 10 people for

every MVA of production.

Favourable location: With three-fourths of India’s landmass accessible by sea,

India is favourably located to export to various destinations across continents.


17

Abundant industrial power availability: The industrial supply of power is

available at reasonable rates in India, an edge in a power-intensive industry over

China and South Africa. China is conserving its energy and has imposed an

export duty on ferro alloys, while South Africa is experiencing a power crisis.

Ore edge: India possesses the sixth largest quantity of manganese ore deposits

in the world, representing adequate backward integration.

Large domestic market: India enjoys the advantage of a growing domestic

steel market. India’s steel production is expected to increase from an estimated

100 MT in 2017-18 to 230 MT in 2030-31 (Source: Ministry of steel).

CHAPTER – IV

PROCESS TECHNOLOGY

4.1 General

Process technology selection and manufacturing route are very crucial for

achieving efficiency and economy. This project envisages setting up of a Ferro

Alloy plant wherein suitable and sized material shall be procured. As such the

process technology area relates to only ferro alloy production.

This plant shall be designed for production of Ferro Alloys (Ferro Chrome, Silico

Manganese, Ferro Silicon & Ferro Manganese). The standard grade of Ferro

Chrome has Cr content of ~60% and Silico Manganese has Mn content of ~60%

and Si content of 14-15%.

The production of Ferro alloys is a continuous slagging process. The oxides of

chromium, manganese, iron, silicon, phosphorous etc. contained in the ore is

reduced by the carbon present in coke/coal in a submerged electric arc furnace.

The reduction of oxide is accompanied by evolution of gases at furnace top.

4.2 Silico Manganese / Ferro Chrome

Silico Manganese is an alloy of manganese with silicon & iron. Ferro Chrome is

an alloy of chromium with iron & silicon with silicon present in smaller quantities.

Ferro alloys are widely used in metallurgy as a complex reducer and alloying

additive in making various grades of steel, with ferro chrome usage limited largely

to stainless steel production, but in significantly higher quantities.

The concept of the use of Silico manganese instead of ferro manganese and

ferro silicon pure into the steel is due to its cost effectiveness, as ferro

manganese and ferro silicon require purer raw materials, which are costlier.

Moreover silico manganese goes for production of refined grades of Ferro

manganese i.e. low and medium carbon ferro manganese. Ferro manganese, on

the other hand is used where Si content in the finished steel has to be controlled

accurately as is the case in steel flat products (sheets and plates).

Silicides of Manganese are more stable compounds than manganese carbides.

Therefore, the higher the Si content in manganese alloys, lower is the carbon

content.


19

Ferro alloys are produced by reduction of ores by the carbon contained in coke

and coal.

The chemical reactions taking place are as follows:-

Decomposition: 4 MnO2 => 2 Mn2 O3 + O2 (at 430oC)

6 Mn2O3 => 4 Mn3O4 + O2 (at 950oC)

Reduction: Mn3O4 + C => 3 MnO + CO

MnO + C => Mn + CO (at 1430oC)

2 Cr2O3 => 2 Cr + 3 O2 (at 1780oC)

SiO2 + C => Si + CO2 (at > 1500oC)

The Cr, Mn and Si thus formed join the alloy.

The excess SiO2, AI2O3, oxides of calcium and Magnesium get generated during

the process and join the slag. 0.7 – 1.0 Tonne of slag produced per tonne of

alloy. This would be sold for land filling purposes. Fluxes may be added to

control the slag fluidity.

Metal (Alloy) and slag are tapped simultaneously 3 - 4 times per shift.

Selection of Plant Capacity

H.C. Silico Manganese and H.C. Ferro Chrome are typically smelted in 5000 -

18000 KVA closed top submerged electric arc furnaces with transformer

secondary voltage 100 – 200 V. The plant will have 4 submerged arc furnaces of

16.5 MVA working for 350 days in a year and 3 shifts per day.

34

POLLUTION CONTROL FACILITIES:

With increasing environmental awareness, it is imperative that due attention is

paid to this aspect right at the planning stage. Of the three major identified areas

of pollution viz. air, water & noise, the extent of water pollution & noise pollution in

ferro alloy manufacturing units is negligible.

As regards air pollution, while gaseous emission are naturally well within the

stipulated limits, necessary control measures will be put in place to ensure that

particulate emission from the furnaces are also well below acceptable/prescribed

safety norms.

8.6.1 Air pollution control

Particulate emission consists mainly of manganese ore dust, coal & coke fines

emanating mainly from the furnace exhaust gases & transfer points of conveying

and handling equipment. The gas emanating from the furnace will be picked up in

the ‘Hood’ above the Furnace and is sucked into the system by negative

pressure. It is shall be first passed through a heat exchanger wherein it shall be

air cooled. The air coming out of the cooler at a temperature of about 120oC shall

be then passed through a modular type ‘Pulse Jet’ Bag Filter where fine dust

particles will be separated and clean filtered air having emission less than 50

mg/Nm3 will be vented out through the stack via an ID fan.

The dust collected in the bag house would primarily consist of fines of

manganese ore, coke, coal and other raw materials fed to the furnace. This would

be processed by the briquetting and/or sintering plants and would be fed back to

the furnaces.

The main areas of fugitive gas emission are:

a) Above the open hearth of the furnace.

b) At the Slag Port and Tapping spout. But the fumes here are negligible.

However control measures to maintain the ambient air quality will be

incorporated.

General Mitigative measures

▪ Stack height of all the APCS will be minimum of 30 m as per CPCB

norms.


35

▪ Green belt along the boundary and inside the premises will be developed

to arrest the dust from fugitive emissions.

▪ Water sprinkling will be done in vehicle movement, loading and unloading

areas. Also all roads within the premises will be made pucca.

▪ Enclosures will be provided for noise generating equipments

▪ Eco-friendly and silent DG sets will be installed.

8.6.2 Water pollution

The water is used for 2(two) purposes, i.e.:

a) Cooling the various equipments in the furnace and gas cleaning system.

b) Domestic consumption.

The water used for cooling purpose is recycled back via the Cooling Tower,

where the scales/dusts carried over by such cooling water invariably and easily

settles down at the Cooling Tower Pond.

Adequate waste water handling, treatment and reuse measures will be taken to

conserve water in the plant. Wastewater, after treatment in the wastewater

treatment facility, would be reused for green belt development and water

sprinkling in other areas within the premises.

The water used for domestic purposes will be divided in 2(two) parts, viz :

a) General Domestic uses for washing, bathing etc.

b) Domestic effluent from Toilets.

The domestic wastewater will be passed through a septic tank – soak pit as

standard practice.

General Mitigative measures

▪ Recycle and reuse of water to conserve the sources.

▪ Implementation of rain water harvesting system for recharge of ground

water or use in the plant

8.6.3 Noise pollution control

To avoid noise pollution, the DG sets and compressors shall confirm to laid down

norms of the pollution control board.


36

8.6.4 Thermal pollution control

There will also be no Thermal Pollution as the entire heat generating equipments

are water cooled and/or thermally insulated with Refractory materials. Hot gas

from furnace cools down in the Gas Hood due to dilution with ambient air.

However, the operational area around the furnace will be hot to warm up to a

distance of 3-5 Meters.

8.7 AIR-CONDITIONING & VENTILATION

Ventilation fans would generally be installed in enclosed premises. Supply ducts

and grills on the ventilation and air conditioning system would be suitably sized

for minimum noise level.

8.8 QUALITY CONTROL FACILITIES

The plant shall have its own quality control laboratory for following functions:

- Analysis of raw materials

- Analysis of products

- Testing of water and Gas samples

The laboratory shall have following sections:

- Sample preparation unit

- Wet chemical analysis section
