Abstract
A control method and apparatus for inhibiting slag entrapment in ladle () during continuous casting production. An optimal control model calculating unit () receives related signals and data sent by a ladle weight detector (), a molten steel flow field detector (), a slag detector (), a sliding gate opening detector (), and a process signal interface unit (), 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 () and a sliding gate controller () 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.
