The present invention discloses a control method for continuous casting steel pouring, wherein: Step one: measuring and reading a steel ladle pouring position signal by a steel ladle position sensor (14) mounted on a turntable of a steel ladle; Step two: judging whether the pouring of the steel ladle (1) has begun therein by a steel pouring optimization control computer (13); Step three: feeding a data of a steel slag measurement sensor (2) mounted above a steel ladle sliding nozzle (15) to an inferential controller ; Step four: in the inferential controller, conducting a comparison between the read data of the steel slag measurement and the manually set value of steel slag, and back to the former step if the measured value of the steel slag measurement is smaller than the manually set value of steel slag; if the current measured value of the steel slag measurement is greater than the manually set value of the steel slag, outputting and feeding a cylinder control variable to a PI controller; Step five: conducting a comparison between the cylinder position signal output by the inferential controller and a cylinder position signal actually measured and a calculation in the PI controller, and an output control of the cylinder driving unit (5) drives the cylinder (3) to move, thus reducing the opening degree of the sliding nozzle (15) of the steel ladle. |
