The invention provides a prediction method for movement of particles in molten steel, and relates to the technical field of metallurgy continuous casting. The method comprises: firstly, collecting physical property parameters of particles in molten steel to be researched, calculating dynamic parameters of the particles according to the collected physical property parameters of the particles, a control equation of a flow field and a movement equation of the particles, and obtaining a numerical model for predicting movement of the particles in the molten steel; according to the obtained numerical model for predicting the movement of the particles in the molten steel, setting an initial value, determining boundary conditions and all control conditions, obtaining a movement result of the particles in the molten steel through calculation, then converting the movement result of the particles into a more visual image form, and displaying the movement of the particles in the molten steel. According to the prediction method for movement of particles in molten steel, a numerical simulation method is used for researching the particle movement in the continuous casting molten steel and the change rule of the particle movement, and the limitation and non-repeatability of experimental research can be effectively avoided.
