The invention discloses a dynamic prediction method and device for the carbon content in the back blowing of the converter. The method comprises: Taking the current converter production process as a new case and the historical converter production process as a historical case, according to the process parameters in the main blowing stage of the new case, the similar cases in the historical case and the process parameters in the back blowing stage are retrieved based on the case-based reasoning algorithm; The carbon content prediction model is trained by using the process parameters in the back blowing stage of similar cases; The process parameters of the post blowing stage of the new case are input into the trained carbon content prediction model to realize the real-time dynamic prediction of carbon content in the later stage of blowing. The invention provides a reference model for the prediction of the end-point of the converter based on the case-based reasoning model and the dynamic control of the end-point of the converter, which can improve the prediction rate of the end-point of the converter based on the case-based reasoning model.
