The applications of the single-hole top lance, the 110-three-holes top lance and the 150-three-holes top lance in the speed of the decarburization are compared. The amount of the Chromium oxidized, and the temperature-increasing speed of the bath is analyzed. The result shows, if the lance gap is set suitably, the 110-three-holes top lance will be the most beneficial to the stainless steel-making in the AOD when the high-carbon pre-metal from the EAF is charged.
