| Abstract: | The present paper analyzes the effect of the mould flux on the quality of CC beam blank, primarily discusses such a few surface defects as web longitudinal crack, pin hole and concave in the flange tip and especially carries out thermodynamic calculation on the pin holes over the surface of the beam blank and theoretically analyzes the causes to those defects and puts forward accordingly the appropriate property index of the mould flux suitable for the beam blank of Ma'anshan Steel. |
