PURPOSE: A method for analyzing slag of molten steel is provided to accurately analyze alumina even in case of being higher than detection limit and to produce a steel material of high quality. CONSTITUTION: A method for analyzing slag of molten steel comprises: a first step of analyzing a first sample to draw analyzed value; a second step of determining whether the value is over standard value; a third step of adding error-correcting value calculated based on a second sample with the analyzed value; and a fourth step of drawing calculated value by alumina(Al2O3) content. The standard value is a detection limit value which is able to perform quantitation of alumina. The second sample is a slag sample containing alumina of high content.
