By means of statistics， calibration and analysis on hot rolled bar and continuous casting production process in Fushun Special Steel Plant，the results show that the original defects of continuous casting billet can be inherited to the hot rolled bar surface， and the main defect generated are cracks. The chemical elements in steel， casting powder， parameters of continuous casting process， cooling and transfer of the billets， maintenance and inspection of continuous casting equipment are all the key factors affecting the quality of casting billets.
