Abstract
A computer implemented process for optimizing the decarburization of a predetermined mass of molten metal by controlling the amount of coolants, the charging time of coolants, the dilution ratio of injected oxygen to inert gas, the changing time of the dilution ratio and the amount of injected gases which includes: considering from a standpoint of kinetic theory the reaction in AOD vessel is composed of following three reactions, i.e., the reaction in the vicinity of tuyeres, the reaction taking place in the ascending process of bubbles and the reaction in the interface between metal and slag; establishing the mathematical Model I; establishing the mathematical Model II calculated capably in short time and kinetically from the result using the mathematical Model I, and from the vessel factor calculated from the data of an actual operation; and further utilizing the mathematical Model II as a controlling program in an actual operation.
