CVS provides plants & equipment for minimills, alsoin “turn-key” solution.

CVS covers the complete design and manufacturingactivities for green-field projects as well asrevamping/upgrading of existing plants andequipment.

CVS manufactures spare parts & components formeltshops & rolling mills.

CVS provides technical assistance and consultingservice to steel production.

Quick Info


CVS headquarter is placed in the industrialregion of Gebze, just east of Istanbul, close to

many major ports

Our modern facilities consists of more than40,000 sqm of closed area and a land ofadditional approx. 40,000 sqm

CVS workforce is formed by over than 500specialized workers and engineers with amodern machinery park to undertake even themost challenging projects.

Over than 200 engineers and administrativeemployees are involved in the design andmanagement of the projects.



CVS - SECONDARY METALLURGYLF. Advantages

The advantages of a ladle furnace canbe 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 thesteel

•Possibilities of wrong analysis limited

CVS - SECONDARY METALLURGYLF Design Advantageous

The Ladle Furnace is conceived forreheating the steel in the ladle placedon a ladle car and will be designed and

built according to the most moderntechniques in the field and will be inparticular provided with:

Water-cooled secondary circuit andwater cooled flexible cablesWater-cooled ladle roof equipped withindirect fume collecting hood to reducesteel oxidationRoof lifting mechanism via hydraulic

cylinder

Electrode arms with reduced electrodepitch diameterWater-cooled secondary circuit and

water cooled flexible cablesElectro-hydraulic electrode regulation
