Summary:PROBLEM TO BE SOLVED: To remove the stuck material to a molten steel ladle by using a stuck material removing device without emptying the ladle. SOLUTION: The molten steel 4 is sucked up into a vacuum degassing vessel 1 by vacuum action and the molten steel level in the molten steel ladle 3 is lowered and the neighborhood of slag line having much stuck material 6 in the molten steel ladle 3 is exposed, and the exposed stuck material 6 is removed by using the stuck material removing device 20. Since the molten steel ladle 3 needs not be emptied, excess equipment, place, time, etc., for removing the stuck material can be saved.
