5. CVS - EAF
Chemical Energy System Concept
CVS has special oxy-burner system for higher productivity
The injection system consists of a set of jet burners installed on the EAF shell.
The jet burners are supersonic oxygen injectors combined with a hydrocarbon
burner, all in the same housing.
Three jet burners are installed in the upper shell’s side wall, while the forth one
is located in the EBT area. The functions of the injection system are :
decarburization of the steel bath
thermal energy input
formation of foaming slag
reduced need of charge carbon with the scrap
the thermal energy is efficiently transferred to the bath with less fuel, lower off-
gas temperature and much better control of CO emissions.
CVS - EAF
Burner Design Concept
The location and the direction of the burners are determined to reduce the cold
spots effect generated by the three-phase arc of the furnace, thus obtaining an
even and faster melting.
• Higher burner efficiency (cleaner walls, reduction of electric energy
consumption)
• Higher supersonic oxygen efficiency (reduction of electrode consumption
and increase of refractory delta life)
• Higher burner power (up to 8 MW burner and 4000 Nm3/h of supersonic
oxygen)
• Carbon injection in the slag (CH4 + N2 cooled) or above the slag (air cooled)

6. CVS - EAF
Burner Positioning Inside Furnace
The lance manipulator for the Electric Arc Furnace is primarily designed for
safe oxygen injection. As well, solid materials like Carbon can be given from
burner case.
The Carbon injection in the bath have demonstrated of outmost importance to
work with proper foaming of the slag and to obtain recarburisation of liquid steel
bath if required to control bath composition.
CVS - EAF
Burner Positioning Inside Furnace
• Very low installation in water cooled copper box
• Refractory saving by cooling block
• Long life (8-18 months)
• Fast substitution time
• Flame shape control
• De-Luxe gas valve stand
• Improve Metallic Yield
• Very flexible automation

7. CVS - EAF
Slag Foaming
Foaming slag is used to increase the
thermal efficiency of the furnace
during the refining period, when the
side walls are fully exposed to the
arc radiation.
A foaming slag will rise and cover
the electric arcs, thus permitting the
use of a high tap setting without
increasing the thermal load on the
furnace walls.
In addition, an electrical arc covered by a foaming slag will have a higher efficiency in
transferring the energy into the steel phase.
CVS -
Slag Foaming
Slag foaming is obtained by
injecting oxygen into the liquid
steel, where mainly iron is
oxidized according to the
reaction:
O2 + 2 Fe = 2 (FeO)
Carbon powder is then injected
simultaneously into the slag
phase where iron oxide is
reduced.
(FeO) + C = Fe + CO (g)
The resulting CO gas is a critical
component in order to obtain a
foaming slag.

The operation executed at the ladle furnace is
an essential part of the secondary metallurgy
treatment, such as refining, adjustment of
liquid steel temperature and chemical
composition with the target to increase quality
of steel.
CVS - SECONDARY METALLURGY

VD / VOD Plant
The purpose of secondary metallurgical steel treatment under vacuum conditions is
to produce high-purity steel having following properties:
low content of harmful elements such as sulphur, phosphorus, trace elements and/or
carbon,
lowering of oxygen, nitrogen and hydrogen gases dissolved in the steel,
as well as major improvements of steel purity, including shape control of non-metallic
inclusions.

RESULTS
• H contents < 1 ppm

• S contents -80/95 %
• C contents < 20 ppm
PROCESS
•Temperature loss during
vacuum treatment
CVS - SECONDARY METALLURGY
VD / VOD Plant
Hydrogen Removal
The final hydrogen content of a heat depends on the pressure of vacuum vessel, the amount
of the purging gas and the CO-gas development.
Even fully killed heats can be treated due to intensive degassing supported by lift gas. For
lowest hydrogen levels the pressure must be lower than 1 mbar with according treatment
times of 15 - 20 min depending on the starting level.
Nitrogen Removal
Even in VD-Plants nitrogen removal is preferably carried out. Having low sulphur and
oxygen levels this process as well requires low vacuum levels with less than 1mbar for
approx. 15 - 20 min.
Argon is purged by the porous plugs from the ladle bottom with approx. 10 Nl/(min, t steel).

14. CVS - SECONDARY METALLURGY
VD / VOD Plant
Sulphur Removal
The final sulphur content of a heat depends on the pressure of vacuum vessel, the
amount of the purging gas and the amount of synthetic slag added prior to vacuum
treatment start. The EAF furnace slag has to be reduced during tapping to values below or
equal to 5 kg/t Steel.
For low sulphur levels the pressure must be lower than 1 mbar with according treatment
times of 15 - 20 min depending on the starting sulphur level. Argon purging by the porous
plug from the ladle bottom with approx. 10 Nl/(min, t steel) has to be ensured.
Light Treatment (Deoxidation)
The liquid steel will be tapped unkilled or semi-killed from the EAF and partly deoxidised
in the VD-plant.
The deoxidation will occur due to the CO-development by natural decarburisation. The
pressure range depends on the C-O equilibrium and is about 40 - 200 mbar.
After 10 - 12 min treatment the final deoxidation will be carried out with Al or others.
Thus large amounts of deoxidation agents can be saved by light treatment.

Scrap preheating Systems
Preheating of scrap by utilizing sensible heat of exhaust gas emitted from an EAF have
been investigated for many years in many plants.As a result of scrap preheating, not
only the electric power and time required for steelmaking but electrode and refractory
consumption has decreased.
Condition of temperature on the preheating system:
- Inlet temperature of preheater: approx. 8000C – 2000C
- Outlet tempearture of preheater: approx. 2500C – 500C
- Temperature of preheated scrap: approx. 4000C – 1000C
- Temperature at combustion chamber inlet widely varies between 12000C to 3000C
according to the time and conditions of the steelmaking stages.
Outlet temperatures of the preheating system stays at low temperatures which
indicates that heat absorption by scrap is fully accomplished. Temperature of scrap
indicates the difference between upper and lower parts of the charging bucket.
Main Profit:
Preheated scrap average temperature is between 150°C - 200°C
The amount of energy saving is 20 – 30 kwh/ton in practice.

Outline for CVS Scrap preheating Systems
•Heat energy contained in a gas evacuated from an EAF accounts for 15 to 20 % of the
total energy used in EAF steel making process and that is 100 – 150 kwh/ton.
•CVS scrap pre-heater is a system which utilizes this heat energy to heat scrap in a bucket
before charged into an EAF and thus contributes towards energy saving.
Gas evacuated from the EAF is led to a combustion chamber through a suction duct
together with air induced through gap between EAF elbow and sliding sleeve duct to burn
CO contained in the gas, a part of this burned gas is introduced in to the bucket placed at
the scrap to heat scrap. After passing the bucket, the gas is returned to the combustion
chamber by a preheating fan. This is called Recycle Flow in the system.
When scrap does not contain oil and other combustibles, the gas after preheating my be
sent to the duct collector. This is called Direct Flow in the system.
For Recycle flow, combustibles contained in the gas after preheating is burned by mixing
with the gas from the EAF. This enables to eliminate an air pollution after dust collector.
CVS -
Outline for CVS Scrap preheating Systems
It is important to minimize gas leakage in a preheating line. For this purpose, special
sealing devices are provided between hood pipe and inlet duct, hood and scrap bucket
top edge, bucket cylinder and clamp shells.
By use of the adequate sealing devices, air introduced into the scrap pre-heater is very
small.
By provision of preheating fan, existing fume treatment plant can employ the scrap pre-
heater without modification.
As the system is fully automatically operated, this system does not require additional
worker.
EAF operation will not be interrupted even if the preheating system run into a trouble.
Recycling method of preheating system can be controlled separately from dust
collector system.
Proper adjustment of the preheating temperature prevents the scrap bucket from being
deformed.

Optimised Process
We lay the foundation for optimized processes with proven, leading products
worldwide, including mechanical and technological engineering for metal production
and rolling as well as process control engineering, drive engineering and power supply.
Integrated online and offline process models reflect decades of practical experience
and help to ensure reliable, reproducible quality.
Our process engineering expertise fuses these products into complete plant solutions
that also accommodate the upstream and downstream processes.
These solutions are the basis for optimal resource use, minimized waiting times and
reduced maintenance and spare parts costs, as well as wide flexibility with respect to
raw materials and the resulting products.
A further factor for competitive production is the quality of information processing.
Production data must be consolidated and compared with planning data to ensure
optimal production flow.

Training and Technology Transfer
Whenever CVS recieves an order for steelmaking equipment, engineering services and
know-how transfer are mutually agreed upon between both parties.
Thanks to our experience, there is no question that we know that this is fundamental
basis for succesful production equipment.
The second step of know-how transfer is an off-site training of customer’s engineers,
technicians and skilled workers.
The main target of training on the customer’s site is to familiarise their personel with
hands-on operation ofthe supplied machines and equipment.
The operators and maintenance personel are trained step by step to prepare them for
successful operation of the equipment.
