The production line utilizes raw materials consisting of 99% copper scrap and bright copper. It employs gas or fuel-fired furnaces for smelting and adopts the upward continuous casting method. This process yields oxygen-free copper rods with an oxygen content of no less than 99.5%, which serve as high-quality materials for wire and cable production—copper wire. This production line is suitable for countries or regions experiencing power shortages and frequent blackouts.
