The results of the study of fine structure of continuous casted bars of oxygen-containing copper produced by casting in the belt water-cooled crystallizer are presented. The character of fractures of samples of copper cast bars in different directions depending on technological parameters of continuous casting was investigated. For determination of chemical composition of samples of cast bars and detection of presence of possible impurities in copper the microspectral analysis was carried out. It is shown that removing of sources of gasing of copper melt leads to decreasing of volume fraction of eutectic Cu-Cu2O, discontinuity flaws and pores in the structure of cast bars.
