| Abstract: | The refining conditions are discussed by means of thermodynamics in order to prevent the precipitation of oxide inclusions during the refinement of zero inclusion super clean steel;the thermodynamic conditions for oxide inclusions in molten steel to be reduced by carbon during vacuum refining are analyzed;and the precipitating conditions of nitride titanium in molten steel are as well discussed. It's pointed out that the reduction reaction of oxide inclusions by carbon in molten steel in the condition of vacuum is controlled by dynamical conditions. Finally the refining process of zero inclusion super clean steel has been analyzed. |
