ABSTRACT OF THE DISCLOSURE A method for producing exceptionally clean steel wherein desulphurization agents are added to the tap ladle during the first one-third volume of steel tapped and then adding a reduced amount of a deoxidizing agent and then adding slag conditioner agents when one-half of the volume of steel is tapped and then adding an expandable ladle cover compound when substantially two-thirds of the volume of steel is tapped. Argon is then blown through the steel at a rate sufficient to create a bubbling action and finally a deoxi- dizing agent is added when the final volume of steel has been tapped. -2-
