The present invention relates to a method for controlling exclusion of slag, the method comprising: a step of excluding the slag after tilting a charging ladle at a fixed angle; a step of taking pictures of a surface of molten steel by using an image input means, when the slag is excluded; a step of producing an exclusion ratio by calculating the area ratio between naked molten steel and the slag based on the pictures of the surface of the molten steel which are taken by the image input means; and a step of stopping excluding the slag, in case the exclusion ration is over a predetermined reference value. [Reference numerals] (AA) START; (BB) YES; (CC) NO; (DD) END; (S1) Exclude slag; (S2) Take pictures of of a surface of molten steel by using an image input means; (S3) Produce an exclusion ratio by calculating the area ratio between naked molten steel and the slag; (S4) Is the exclusion ratio more than a predetermined value?; (S5) Stop the exclusion of the slag |
