Prediction method for components of molten steel in tundish in continuous casting and mixed pouring process

The invention discloses a method for predicting the components of molten steel in a tundish in a continuous casting mixed pouring process, which comprises the following steps of: S1, acquiring the weight m0 of the molten steel in the tundish at an initial moment, the component C0 of the molten steel in the tundish at the initial moment and the component CL of the molten steel injected into the tundish, and calculating the flow Qout of the molten steel flowing out of the tundish; s2, the target tonnage mtarget of the tundish and the time t'required for the tonnage of the tundish to rise from m0 to mtarget are obtained; s3, the flow Qin of the continuous casting molten steel injected into the tundish is calculated; s4, the tundish molten steel component Ct at the moment t is calculated; the calculation process is simple and convenient, the change of molten steel components in the tundish along with time can be conveniently, efficiently and intuitively obtained on a production site, so that the mark of the mixed
