Claim:
1. A method of processing melt-pool, the method comprising: preparing a melt-pool; preparing a dephosphorization flux controlling a phosphorous (P) component contained in the melt-pool; submerging an impeller into the melt-pool; supplying the dephosphorization flux into the impeller to blow the dephosphorization flux into the melt-pool; rotating the impeller to stir the melt-pool into which the dephosphorization flux is blown, wherein the stirring comprises: stirring the melt-pool such that a first stirring flow direction of the melt-pool generated by a blade of the impeller corresponds to a second stirring flow direction of the melt-pool generated by the dephosphorization flux blown into the melt-pool, wherein the preparing of the dephosphorization flux comprises: preparing a main raw material including BaCO wherein a molar ratio of BaCO
