The invention relates to a converter internal reaction digital twin control method and device and a storage medium. The method comprises the steps that in the smelting process, the audio frequency of a converter mouth is collected through the audio frequency slagging technology, and audio frequency features are obtained through the audio frequency; the audio frequency features are sliced to obtain feature fragments; the curve trend, the slope and the variable quantity of the feature fragments are analyzed, and values related to the feature fragments are compared with the value of a preset abnormal boundary so as to judge whether smelting abnormity occurs or may occur or not; an in-furnace reaction digital twin is constructed; and the audio frequency features are imported into the in-furnace reaction digital twin according to a time sequence corresponding mode, the in-furnace reaction digital twin is driven through the audio frequency features, and corresponding remedial operation is executed according to the
