The raw materials used in this production line are copper scrap and electrolytic copper with 99% copper content, and the advanced electric furnace is used to produce oxygen-free copper rods with oxygen content of not more than 0.02%, total impurity content of not more than 0.05%, and copper content of more than 99.5% by using the upward-drawing method of continuous casting process. This production line can produce 500T of copper per month. Due to the process of this production line is selected on the introduction method, this production line equipment investment is small, flexible plant layout, can also be in the same machine to produce different specifications, different varieties of copper.
