ABSTRACT OF THE DISCLOSURE Continuous treatment of hot metal between a blast furnace and the torpedo car involves establishing silicon and phosphorus concentration followed by adding silicon and phosphorus reduction agents. The process permits low phosphorus levels to be attained simply and cheaply. The hot metal thus treated is suitable for subsequent use in the convertor for the preparation of steels with a low and very low impurities content.
