Sažetak

Paper is focused on the observation of the conditions causing defects origin in continuously cast billets in the first phase of solidification and shell formation in the mould. Work is also focused on the area of casting failures. Experiences were aimed at steel preparation for casting from the viewpoint of desoxidation and modification of inclusions, facility influence on solidification and formation of shell, influence of the taper of the mould, and on vibrations influence and origin within primary cooling system – oscillation mechanism – mould. The method of measurement was tested, incl. the analysis of acoustic spectrum for phenomena assessment within continuous casting. Conclusions resulted in modification and changes of shapes of moulds, incl. casting technology of round billets.
