Abstract

Process for the production of modified iron comprising the steps of containing the iron in molten form, in a prepared state for modifying, in a containing vessel having a sliding gate valve mounted in a wall thereof at or adjacent the base thereof, the sliding gate valve having an opening in the sliding gate connected to a source of modifying agent containing material and selectively movable into and out of alignment with an orifice through the wall of the vessel and comprising the steps of moving the gate so that modifying agent containing material is injected entrained in an inert gas through said opening therein into the orifice in the wall of the vessel for the formation of modified iron therein.
