A desulfurizing method in a ladle furnace is provided to improve productivity by omitting an additional post-treatment process for a desulfurizing process. A desulfurizing method comprises the steps of checking components and temperature of molten iron, preparing sub-materials for reforming a slag when the content of sulfur in the molten iron exceeds a target level, refining the molten iron in a ladle furnace, inputting the sub-materials into the molten iron to reform the slag, checking again the components and temperature of the molten iron after inputting the sub-materials, raising the temperature of the molten iron if the temperature of the molten iron is lower than the target temperature, imputing alloy iron containing Ca if the sulfur in the molten iron exceeds the target level, and performing a bottom bubbling to remove Ca. |
