  2. 2. CVS MAKINA - Company Presentation CVS provides plants & equipment for minimills, also in “turn-key” solution. CVS covers the complete design and manufacturing activities for green-field projects as well as revamping/upgrading of existing plants and equipment. CVS manufactures spare parts & components for meltshops & rolling mills. CVS provides technical assistance and consulting service to steel production.CVS MAKINA - Company Presentation Quick Info CVS headquarter is placed in the industrial region of Gebze, just east of Istanbul, close to many major ports Our modern facilities consists of more than 40,000 sqm of closed area and a land of additional approx. 40,000 sqm CVS workforce is formed by over than 500 specialized workers and engineers with a modern machinery park to undertake even the most challenging projects. Over than 200 engineers and administrative employees are involved in the design and management of the projects.
  3. 3. CVS - SECONDARY METALLURGY LF. 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 METALLURGY LF Design AdvantageousThe Ladle Furnace is conceived forreheating the steel in the ladle placedon a ladle car and will be designed andbuilt 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 oxidation Roof lifting mechanism via hydrauliccylinder Electrode arms with reduced electrodepitch diameter Water-cooled secondary circuit andwater cooled flexible cables Electro-hydraulic electrode regulation
