Abstract

A weak pre-deoxidation process (W.P.D. process) for the production of aluminium- and titanium-killed steel. In this process an adequate amount of a silicium-containing ferro-alloy is added to the molten steel during its tapping. The ladle is subsequently transferred to an aluminium wire feeder or to a ladle-injection treating equipment for performing the final stage deoxidation process.
