ABSTRACT:
In a steel refining process control over the composition of the product is maintained in part by supplying blowing oxygen to the molten material in an amount predetermined for achieving FeO content which is required for slagging the manganese and phosphorus. Lime, if required, is added in accordance with the FeO content and the silicon content to give saturation in lime and in the quasi-ternary system CaO--FeO--SiO.sub.2 at the final temperature of the metal.
