PURPOSE: A method for supplying oxygen into converter is provided which is capable of improving removing efficiency of skull of furnace mouth and inner wall by repeatedly tilting converter to charging and tapping sides to a certain angle during the process of blowing high pressure oxygen into the converter through oxygen lance. CONSTITUTION: The method comprises the steps of vertically erecting the converter (1) so that the center of the furnace mouth (14) of the converter (1) is perpendicular to a converter support bar; repeatedly tilting the converter to the direct opposite charging side to a certain angle after tilting the converter (1) to the tapping side to a certain angle centering around the converter support bar during opening signaling of an oxygen blowing valve (22) for blowing oxygen into the converter through an oxygen lance (17); and changing the converter (1) into the upright initial state by close signals of the oxygen blowing valve (22) for stopping oxygen blowing through the oxygen lance (17), wherein the converter (1) is tilted in such an inclined angle that high pressure oxygen of the oxygen lance (17) is not deviated to the outer side of the furnace mouth centering around the converter support bar, and wherein the converter (1) is repeatedly tilted at a speed proportional to injection speed of the high pressure oxygen injected into the converter (1) through the oxygen lance (17).
