<p>Provided is a manufacturing method of clean steel, which comprises: a step for preparing a CaO-Al2O3-SiO2-MgO-based tundish flux; a step for preparing a modified flux by adding an alkali metal oxide to the tundish flux; a step for melting the modified flux and stainless steel; and a step for cooling the modified flux after maintaining the modified flux for a certain time after melting the modified flux. Compared with a method not using the modified flux to which the alkali metal oxide is added, the manufacturing method according to the present invention reduces more inclusions in the stainless steel and also controls the compositions of the inclusions.</p> |
