Abstract
	Elimination of non-metallic inclusions from molten steel into slag is supported by light agitation of the steel bath in the ladle, that is achieved by inert gas bubbling - stirring. The inert gas light bubbling is used as a final technological step in ladle treatment of steel. The aim of presented work was to study the influence of length of Ar stirring on removal rate of non- metallic inclusions. Three different times of Ar stirring were tried: 4, 8, and 12 minutes. It was found a big difference in inclusions removal rate between 4 and 8 minutes of Ar stirring, but very small difference between 8 and 12 minutes of Ar stirring. From this fact follows that 8 minutes of inert gas light bubbling is effective enough to remove most of non-metallic inclusions into slag from molten steel in ladle.
