There are a number of factors affecting the quality of oxygen free copper wire rod, such as quality of the raw materials, construction of the manufacturing facilities, quality of the graphite die, assembly of the crystallizer, selection of the process parameters, auxiliary materials and operation by the workers.

This articles first analyses the causes of the unsteady quality of the oxygen free copper wire rods produced by some factories, due to which is impossible to draw the copper wire rods into copper wires thinner than Φ 0.

Effects of RE on Technological Processing and Product Properties of Oxygen Free Copper Rod;

Brazing between high purity alumina ceramic and oxygen-free copper;

A novel technology of electromagnetic deoxidization (EMD) & electromagnetic continuous casting (EMC) for quality oxygen-free copper (OFC) processing was presented and industrial experiments and the production of OFC with this technology were completed.

Inconnectionwiththe technological characteristics ofthe productionofoxygen-free copper,factors whichinfluence the quality of oxygen-free copper are analysed,including:the productive methods,original and auxi-material,technologies for smelting and casting and inspectional methods.

Gas Hole Characteristics and Forming Mechanism of Oxygen Free Copper Rod with Up Casting;

This paper introduces the qualities and applications of oxygen free copper,analyzes its production technology together with its main factors influencing its quality,points out the measures for controlling the quality and studies the means for eliminating the sources of oxygen.

Effect of trace Ag on the properties of oxygen free copper was studied.
