PROBLEM TO BE SOLVED: To provide a method for refining molten chromium-containing steel by which the oxidized loss of the chromium with an oxygen-blowing is minimized, the amont of reducing silicon is reduced and the damage of refractory in a converter can be prevented. SOLUTION: In the method for refining the molten chromium-containing steel, by which the molten iron subjected to a pre-treatment is charged into the converter, and the decarburize-refining is performed while blowing oxygen and adding Fe-Cr alloy being Cr source, the Si content incorporated in the Fe-Cr alloy is regurated to≥02 to≤2 mass%, then the alloy is added into the molten metal, thus the oxidized loss of chromium by oxygen-blowing is minimized, the amount of reducing silicon is reduced and the damage of the refractory in the converter is prevented.
