1, raw material problem. The quality and composition of raw materials in copper rod production will affect the copper powder content. Excessive impurities or elements such as lead and antimony in raw materials will lead to an increase in copper powder content.

2. Operational problems. The production of SCR continuous casting and rolling copper rod involves melting, casting, rolling and other links. If the process requirements are not strictly followed or the equipment fails, the copper powder content will also increase.

3. Equipment problems. The production of SCR continuous casting and rolling copper rod needs a series of equipment, and the performance and state of these equipment will directly affect the copper powder content. The aging, damage or untimely maintenance of equipment will also lead to the increase of copper powder content.
