The invention discloses a method and a device for predicting the carbon content and temperature of molten steel at the end of a converter. The method comprises: treating each converter smelting process as a case and describing the converter smelting process; Among them, case description includes case feature description and case solution description. Case features include single value type influencing factors and time series type influencing factors; The solution includes the carbon content and temperature of molten steel at the end of converter; Taking the current converter smelting process as the problem case and the historical converter smelting process as the historical case, the similar cases in the historical cases are retrieved based on the case-based reasoning algorithm; Based on the retrieved similar cases and the carbon content and temperature of converter end-point molten steel, the predicted values of carbon content and temperature of converter end-point molten steel of problem cases are obtained through case reuse. The prediction accuracy of the method is better than the existing prediction model and can meet the requirements of converter on-site production.
