The Chinese copper wire rod producer, Eastern Copper from Linyi, Shandong Province recently commissioned the second CONTIROD CR 3700 continuous copper wire rod plant.


The complete plant was supplied by SMS Meer and has an annual capacity of 320,000 tonne of rolled wire rod. It is thus the plant with the highest capacity in China.


Dr Michael Schwarze form SMS Meer said that “The new plant impressed Eastern Copper with its high energy efficiency, good productivity and product quality. With this increase in production capacity, Eastern Copper aims to expand its market share.”


The new plant consists of a shaft-type melting furnace followed by a 20 tonne holding furnace. In order to achieve high wire rod qualities, the CONTIROD line is equipped with a Hazelett twin belt caster and a continuous SMS rolling mill with 14 mill stands.


The mill stands are equipped with individual drives and the main drives of the mill and the fans all feature variable frequency 3 phase AC motors, thus reducing the energy consumption. The modern electrical systems and automatic process control from SMS Meer ensure smooth and reliable operation. The plant is completed by an automatic compacting, strapping and film packaging line for the wire rod coils.


The CONTIROD plant achieves a casting capacity of 48 tonnes per hour with a casting cross section of 8,610 mm² and a casting speed of approx. 10 meters per minute. The standard finished size is 8.0 mm in diameter.
