  • Patent number: 11154926
    Abstract: A control method and apparatus for inhibiting slag entrapment in ladle (1) during continuous casting production. An optimal control model calculating unit (11) receives related signals and data sent by a ladle weight detector (4), a molten steel flow field detector (5), a slag detector (7), a sliding gate opening detector (9), and a process signal interface unit (10), performs calculation and analysis according to an optimal control model to obtain a corresponding optimal control strategy, and outputs the strategy to an electromagnetic brake (6) and a sliding gate controller (8) for slag entrapment inhibition control. Regarding the two processes where a vortex may be formed, by means of different optimal control strategies, which respectively inhibit or destroy the formation of a vortex, slag generation is postponed, and molten steel may flow out without bringing slag out, thereby reducing residual ladle steel and improving molten steel yield.

  • Publication number: 20150190863
    Abstract: 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: conduct
