By testing the thermal process of copper scrap smelting system and analyzing operation status of equipment

the problems existed in low oxidized copper rods production were found as follows:poor fuel quality

irrational burner structure

low metal recovery rate and high impurity in products. To eliminate these problems

a set of gravity duster separator with purification and water seal integrated is employed to improve the fuel-gas quality

the high-velocity spiral burners are used to enhance the combustion efficiency and the temperature uniformity in the furnace

low-temperature slag skimming technology is applied to prevent the ferrous impurities into the liquid copper

and temperature control during oxidation-reduction period technology is adopted to improve copper percentage recovery and product quality

shortening smelting cycle. Through above mentioned measures

the energy consumption and copper loss in the copper scrap smelting process are reduced

and quality of copper rods is improved

and the properties of low-oxidized copper rods such as elongation and torsion are superior to industry standard

moreover

pollution of scrap-gas on environment is relieved.
