DEVICE FOR CONTROLLING DESULFURIZATION OF MOLTEN IRON AND METHOD THEREFOR

摘要

The present invention relates to a control device of a hot metal desulfurization inside a ladle and a method thereof comprising: a rotating driving part for agitating a hot metal inside a ladle by rotating the shaft of an impeller; a distance measuring means, which is fixed and arranged in the upper part of the impeller, for measuring the location of the impeller when the impeller agitates the hot metal in the ladle; a supplementary raw material supplying device for putting a supplementary raw material into the ladle when the impeller agitates the hot metal, and where the length of an inlet is extended to the impeller when the supplementary raw material is put; and a controlling unit for controlling the supplementary raw material to be put into the impeller in the supplementary raw material supplying device when the distance to the impeller measured through the distance measuring means is the same as a preset reference distance.
