3. CVS - SECONDARY METALLURGY
LF. Advantages
The advantages of a ladle furnace can
be defined as follows :
•Saving of ferroalloy
•Saving of energy
•Increase productivity
•Decreasing refining time of EAF
•Decreasing tapping temperature at EAF
•Precise temperature control
•Improved of inclusions, cleanliness of the
steel
•Possibilities of wrong analysis limited
CVS - SECONDARY METALLURGY
LF Design Advantageous
The Ladle Furnace is conceived for
reheating the steel in the ladle placed
on a ladle car and will be designed and
built according to the most modern
techniques in the field and will be in
particular provided with:
Water-cooled secondary circuit and
water cooled flexible cables
Water-cooled ladle roof equipped with
indirect fume collecting hood to reduce
steel oxidation
Roof lifting mechanism via hydraulic
cylinder
Electrode arms with reduced electrode
pitch diameter
Water-cooled secondary circuit and
water cooled flexible cables
Electro-hydraulic electrode regulation
