The crisis of steel market was started in the end of 2008, as all other markets.
And it has been continued throughout the entire 2009.
In the end of 2009, the effects of crisis was began to pass. And again the market was
started to grow up.
But something was changed. Maybe the costs are not higher before crisis but profits are
lower.
Energy and scrap are the biggest cost of meltshops.

STEEL INDUSTRY AND ENERGY
Why the energy efficiency is important?
Approximately 12% of energy produced all over the world is consumed at Iron & Steel
Industry.
So we can understand the importance of energy efficiency.
With the increasing of steel production studies of to reduce the energy consumption are
of steel production, studies of to
became important.
But, 50% of consumed
But 50% of consumed energy is loss due to several reasons
is loss reasons.
In the end of these studies, the recovered energy will be very high, and the costs can be
reduced with possible new concept i
d d ih ibl investments.

6. STEEL INDUSTRY AND ENERGY
5 main input for meltshops with EAF
1. Scrap
2. Energy
3. Refractoryy
4. Ferro Alloys
5. Electrodes
To reduce the scrap cost is limited for steelmakers but they can recude energy
consupmtion themselves.
The scrap cost is determined by market. And request of steel production is increased
every day.
Based on this growing, coke, iron ore and scrap requested are increased so much and their
international costs will be higher than the past.
The difference between product and input price, is determined to the profit of
11
steelmakers.
STEEL INDUSTRY AND ENERGY
There are a lot of inputs and outputs of EAF.
But the most important and can be reduced one is electricity energy.
p y gy
How can we reduced the electricity energy consupmtion?
With classical methods this is not advantage for the competition because of all important
methods,
competitors knows to use this energy input.
With new concepts, this can be created to make a difference if you can find the right
investments.

7. CHEMICAL ENERGY
In the EAF melting process the chemical energy is playing an important
role since production costs and productivity have to be always
improved.
It is now common practice to use between 30% and 40% of the total
energy input to the EAF being supplied through oxy‐fuel burners and
oxygen lancing.
yg g
Exothermic reactions are provided very
important energy input.
At EAF, while the energy inputs are calculated;
Total oxygen which blows from burners (burner
mode & jet mode) and lance manipulator, total
NG which blows from burners, total C which is
coming from with charge injection and scrap
charge, scrap,
total removal elements are going into the
13
calculations.
CHEMICAL ENERGY
The Advantages of the CB system are:
‐ Operate the furnace with multipoint oxygen injection that allow a more
intensive and/or efficient chemical energy utilization.
‐ Operate the furnace with multipoint carbon injection to better foam the
slag.
‐ Minimise operation with slag door open reducing the energy losses via
furnace off gas.
f ff
‐ Avoid any manual lancing operations.
‐ High lifetime and reliability of the equipment.
‐ Full process automation
Full process automation.
The CB system has the following benefits on the furnace performance:
‐ Reduced electrical energy requirements, as less energy is lost in the off
gases.
‐ Better energy and thermal balance inside the furnace.
‐ High flexibility and high efficiency on chemical energy utilisation.
14

8. CHEMICAL ENERGY
Along with the main target, the other reasons for using chemical energy for melting are:
‐ much greater flexibility of processes with regard to raw materials and energy availability
‐ increased productivity while simultaneously improved energy efficiency
The complete system installed on the furnace enables the following functions:
‐ Fuel utilization: the fuel burners are installed onto the cold spots in order to balance the total
energy input into the furnace on the basis of the process requirements.
‐ Steel bath refining: the multipoint oxygen injection allows for fast and homogeneous bath
decarburization and superheating.
‐ Slag foaming: the checking of the covering of the bath and the arc by a suitable management of
the carbon injection
injection.
yg ;
Burner oxygen;
‐ Burner fuel (Natural Gas, LPG, CH4, etc.);
‐ Lance oxygen;
‐ Carbon injection.
15
CHEMICAL ENERGY
To reduce the power on time, the electrical energy input to the furnace must be rather aggressive.
The correct power program must be used and is designed to balance both electrical and chemical
(burner and lance) power inputs. In the early stages of melting a short arc is selected to avoid
excessive damage to the roof panels from arc flare. This slight reduction in the initial power is
however compensated for by the CB burner‐injector units which are fired very quickly during initial
arcing and maximize the energy input to the cold scrap.
Slag foaming i extremely i
Sl f i is t l important if an aggressive arc i t b maintained th
t t i is to be i t i d throughout th h t A
h t the heat. As
the scrap level reduces in the furnace and flat bath conditions are approached the height of the
foaming slag must be increased to completely submerge the arc and prevent damage to the water
cooled panels

REMOVAL OF ELEMENTS C Si and Mn
C,
All of the heats of formation of the oxides are exothermic so oxidation of the elements actually
helps to raise the temperature of the bath. In addition the formation of CO helps to stir the bath and
homogenise it whilst promoting further slag‐metal reactions The heats of formation can be

2Al(l) + 2/3O2(g) = Al2O3

2C + O2(g) = 2CO (g) ΔHR = ‐28 Kcal/mol
2Fe + O2(g) = 2FeO ΔHR = ‐63.5 Kcal/mol
Carbon alone is not enough to create a foaming slag. Often the chemistry of the slag itself is
ignored. The CO bubbles generated in the bath from direct oxidation of carbon, or those created in
the slag by mixing C and O or reducing FeO will all escape from the slag very quickly unless the slag
composition is correct.

CVS scrap pre‐heater is a system which utilizes this
heat energy to heat scrap in a bucket before charged
into the EAF and thus contributes towards to energy
saving.
i
Evacuated gas from the EAF is flowed to the
combustion chamber, and via the second out way
with another duct pipes, hot gas is flowed to the
scrap buckets, gone into bucket to heat scraps and
after that gone out from bottom of scrap bucket and
via duct pipes, mentioned gases are gone to the FTP
after gives existing heats to the scraps.

Our invention comprises an electric arc furnace for continuous
charging of ferrous materials and semi continuous tapping of
molten steel when it is adequately refined.

13. ONE CHARGE EAF
Most modern furnaces are designed to operate with a minimum of back‐charges. This is
g p g
advantageous because charging is a dead‐time where the furnace does not have power on and
therefore is not melting. Minimizing these dead times helps to maximize the productivity of the
furnace. In addition, energy is lost every time when the furnace roof is opened.
This can amount to 10–20 kWh/ton for each occurrence.
Most operations aim for 2 to 3 buckets of scrap per
heat and will attempt to blend their scrap to meet
this requirement Our invention achieve a single
requirement.

CONTINUOUS CHARGING SYSTEM
29
EPC SYSTEM
CVS MAKINA has a commercial cooperation with KR Tec company which has developed a
New Generation concept in Arc Furnace Steelmaking, ENVIRONMENTAL PREHEATING &
CONTINUOUS CHARGING SYSTEM (EPC).
Idea behind the challenge is to recover the heat lost to FTP system by the application of
Scrap Preheating.
The EPC System combines the advantages of the
preheating efficiency of the chamber and the
continuous scrap feeding
feeding.
The EPC System is a new generation of economical
arc furnace
furnace.
EPC system overcomes all the missing items of the
existing Preheating system.
30

16. EPC SYSTEM
One of the issues of the EPC System is to charge the scrap independent of the electric arc furnace
taken into consideration the environmental aspects.
The EPC System is installed beside the EAF and the preheated scrap can be charged continuously by
the telescopic feeder system in the melting chamber during Power On.
Even during charging of the scrap basket into the EPC System, the system is always airtight and a
small amount of dust can only escape. Furthermore, the design has been considerably simplified to
increase the reliability and the profitability of the investment, reducing the ROI by less than 12
months.

35
EPC SYSTEM
The scrap basket will be charged into a drawer of the EPC system which is in waiting position.
While this position the front wall of the drawer is closing the preheating chamber and the
melting process in the EAF and preheating doesn`t have to be interrupted.
After filling of the drawer by the scrap basket a slide gate on top of the EPC System will be closed.
Than the drawer will be forwarded by hydraulic cylinders to the preheating chamber and the
scrap falls smoothly inside the pre‐heating chamber where it will be preheated.
If the drawer is in front position, the back wall of it, is closing to the pre‐heating chamber.
A special design of the off gas duct together with a water cooled regulation flap allows to control
the preheating effect in the pre‐heating chamber.
