<p>The present invention relates to a steel manufacturing method. The steel manufacturing method comprises: a step of obtaining slag generated in a steel manufacturing process and containing iron (Fe); a step of drying the slag; a step of charging a converter with molten iron; and a step of putting the slag in the upper part of the molten iron charged into the converter. Also, the steel manufacturing method according to the present invention can recycle the slag generated in the steel manufacturing operation by simply processing the slag without an additional refining step; thereby simplifying a slag processing process, increasing the recycling efficiency of the slag, and reducing the processing costs.</p> |
