copper magnet wire is often used in motor windings. The conductive metal used in motor windings is mainly copper, with a purity requirement of 99.95 or more. Formal magnet wire production companies all use oxygen-free rods, while some low-end companies usually specialize in supplying motor repair units. The material procurement link is not strictly controlled, and they even use the purchase of waste magnet wires to process bright rods.

Due to the different processes of producing copper rods, the oxygen content and appearance of the produced copper rods are different. The copper rods produced by the above-mentioned process have an oxygen content below 10ppm (one million molecules), which is called oxygen-free copper rods; the copper rods produced by continuous casting and continuous rolling are hot-rolled under protective conditions, and the oxygen content is 200-500ppm In general, the copper produced by this method has a bright appearance, sometimes called polished rod or hypoxic rod.

Oxygen-free copper rod and up-drawing method

The up-citation method is a new process for producing oxygen-free copper rods. It was first developed by the Shanghai Cable Research Institute of the Ministry of Machinery Industry in China. It has advanced process technology, good product quality, low unit energy consumption, and flexible production varieties and specifications. It has the characteristics of strong adaptability, no pollution from three wastes and low investment. It is an ideal process for copper conductor and copper material processing.

Continuous casting and rolling process

The full name of continuous casting and rolling is Continuous Casting Direct Rolling (English: Continue Casting Direct Rolling, CCDR for short), which is to pour liquid metal into a continuous casting machine to cast a blank (called a continuous casting billet), and then without cooling, After being kept in the soaking furnace for a certain period of time, it directly enters the rolling process of the shaped metal profile in the hot continuous rolling mill.
