As a control method and apparatus for suppressing the incorporation of slag in the ladle 1 during continuous casting production, the optimization control model calculation unit 11 includes a ladle weight detector 4, a molten steel flow field distribution detector 5, a slag detector 7, The sliding gate opening degree detector 9 receives the related signals and data transmitted from the process signal interface unit 10, analyzes it through an optimization control model calculation, and obtains a corresponding optimization control strategy to obtain the electromagnetic brake 6 and By outputting to the sliding gate controller 8, slag mixing suppression is controlled, and for the two processes in which vortices are formed, through different optimization control strategies, the formation of vortices is suppressed and destroyed, respectively, to delay the generation of slag and at the same time. It realizes the outflow of molten steel without outflow, and improves the molten steel yield by reducing the residual steel in the ladle.
