ABSTRACT A method is provided for removing sulfur and hydrogen from steel by the steps of pouring a stream of steel, low in oxygen and free of slag into a vertical tube installed in a ladle which extends from the bottom of the ladle to the top of the ladle, providing a means to introduce a flow of inert gas into the bottom of the tube to provide a stirring action within the tube, adding a lime based slag with a large capacity to absorb sulfur into the tube; adding ferro-alloys and metals into the tube which are known to enhance desulfurization and are necessary to achieve the specified composition of the steel; utilizing the stream of inert gas introduced into the bottom of the tube as a means for hydrogen removal.
