SCRAP SHREDDER

12. SCRAP SHREDDER
The Scrap Shredder is designed to shred
steel turnings, shavings, borings …etc
into 20‐50 mm chips. Shredder has a
robust structure and machines to shred
scraps between two strong rolls. These
rollers are operated by four
hydromotors.
hydromotors To prevent the scrap to
move through the motors, sheets are
settled on the motors.
System is designed for working light and
heavy demolition scrap. One of the
biggest advantage is quick process time.

14. S C R A P P R E ‐ H E AT I N G S Y S T E M
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.
g
S C R A P P R E ‐ H E AT I N G S Y S T E M
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
into the bucket, placed
at the scrap , to heat
scrap.

Preheating is burned by mixing with the gas from the EAF. This enables to eliminate an air
pollution after dust collector.
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 though 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.

SCRAP CLEANING SYSTEM

17. SCRAP CLEANING SYSTEM
The aim of this machine is to clean the scrap before introducing it into
the furnace. Steel plants all over the world have shown their interest in
p
this machine, due to the poor quality of the scrap and its recent price
increase.
SCRAP CLEANING SYSTEM
