[0002] Low oxygen copper rod refers to a copper rod with an oxygen content of 200 (175) - 400 (450) ppm. Generally, when drawing copper wire with a diameter of > 1mm, the advantages of low oxygen copper rod are more obvious. With the development of the electrical industry, the market demand and purity requirements for cables, wires and other materials are getting higher and higher. Low oxygen / oxygen-free copper rods are widely used to guide electrical cables. The current production of low oxygen copper rods mainly adopts continuous casting and rolling process. After the raw copper is melted, oxidized, reduced, and tapped, it enters the continuous casting and rolling equipment for casting to obtain copper rods.

The existing impurity cleaning method heats the impurities to float to the top for cleaning, but the floating speed of the impurities is slow, which can easily cause some impurities to be unable to float out, thus affecting the cleaning of impurities. At the same time, when the steel raw materials are heated and melted, the internal impurities will produce a strong odor, affecting the working environment, and the reliability and practicality of use are low.
