COPPER REFINING

Copper is used mainly as an electrical conductor in industry. Electrical conductivity, the most distinguished property of copper, is improved to the required level by electrolytic refining in a tankhouse.

The classical refining process at ERBAKIR starts with melting blister copper and / or suitable copper scrap obtained from domestic and foreign sources in a Thomas type furnace. LPG (Liquid Petroleum Gas) is used as fuel in the melting process. During the melting in Thomas furnace copper gives a typical green color to the flame. The liquid copper gets the suitable form for loading into the electrolysis cells after solidification in the moulds.

Electrolytic copper scrap arising at various stages in the plant can be reutilized in the refining. Copper is one of those few materials which can be recycled again and again.

Pure copper deposits on the cathode plates during the long electrorefining process.

The cathodes taken out of the tankhouse cells have a fantastic color which is first indicator of the ER-BAKIR wire quality, highly appreciated by its customers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
THE CONTINUOUS CASTING AND HOT ROLLING PLANT

Electrolytic copper is the most widely used material for electrical energy and signal transmissions that are the most fundamental and essential requirements of the modern world.

The copper rod which is the main input material for the plants making copper conductors is produced metuculously by people devoted to their jobs at ER-BAKIR Continuous Casting and Hot Rolling Plant.

The liquid copper obtained by melting cathodes in the shaft furnace flows first into the holding furnace and then is directed through launders and tundish to the casting machine. One of the important factors influencing the quality of the rod is the solidification process which takes place in the HAZELETT casting machine. The hot cast bar so obtained is transformed to rod in the rolling mill. The rod then passes a pickling line where it gets a bright surface, cools down and is sprayed with a protective solution and then directed to the coiler. There, it is formed into coils. The production is completed by the packing operation.

ER-BAKIR has started producing rod with the Italian PROPERZI CONTINUUS technology in 1985. The know-how and experience gained there helped the successful realization of the CONTIROD investment at the end of 1999. The new 18 t/h production line is fully automated.

WIRE DRAWING, BUNCHING AND STRANDING
The rod produced in the Continuous Casting and Hot Rolling Plant is processed in the Wire Drawing, Bunching and Stranding Plant which is equipped with the state-of-the-art machinery.

The high capacity and standard of equipment installed in this department have enabled Er Bakir to establish a significant and important position in this market sector.
 
Products conforming both to national and international standards as well as products meeting specific customer requirements are produced by knowledgeable, experienced people who accept quality as a way of living.

Annealed or hard drawn wire of various diameters are produced from Er Bakir rod by rod breakdown machines. These products are either sold or used as inlet wire for tin plating and further wire drawing processes.

Tin plating is an electrolytic process. The tin plated wire may be sold directly or more often be used as inlet wire for the intermediate single-end and mult- wire-drawing processes.

Intermediate, fine wire and multi-wire drawing machines produce either tinned or plain wires as finished customer products or for use as feed wire to the bunching and stranding machines. These machines produce a wide array of normal bunched, concentric stranded and ropelay conductors.
