The present invention relates to a method for predicting the degree of contamination of molten steel during ladle exchange. The method comprises: setting a casting quantity (Q) and a residual quantity of residual molten steel (Qrm); calculating, based upon the Qrm with proportional coefficients, a casting amount (Qplug) and a casting amount (Qpeak); determining preliminary degrees of contamination; and selecting the smaller of the preliminary degrees to obtain degrees of contamination. |
