| Abstract: | According to the existing problems in ladle furnace alloying model,its mathematic mechanism was analyzed first,and it was indicated that the essence of ladle furnace alloying compute is of linear programming.Then the question of ladle furnace alloying was transformed into issue of simplex algorithm,its specific implementation was given,and its result was verified.Finally the ladle furnace process control system with alloying model was introduced.The operation of this system showed that this model converged quickly,and it can meet the need of production in real time. |
