| 摘要 |
The present invention relates to a method for refining a steel sheet and, specifically, to a method for refining a steel sheet manufactured through a continuous casting process, comprising: a first step of decarbonizing molten metal by injecting Al and oxygen gas to the molten metal; a second step of processing reduction desulphurization and deoxidizing the molten metal by injecting a deoxidizer into the molten metal; and a third step of tapping the molten metal by injecting Al into the molten metal. The present invention provides the method for refining a steel sheet capable of preventing bleeding through a continuous casting process, and securing the casting temperature necessary for the continuous casting process by raising the temperature of the molten metal by injecting Al in the first step. |
