ABSTRACT:
A apparatus is disclosed which is utilized for treatment of molten metal contained in a vessel by injection of powdered reagent below the surface of the molten metal which includes an elongated lance body containing longitudinal conduits for delivery of the powdered reagent below the surface of the molten metal, a first and second reagent supply device and a control device which independently regulates the flow of the reagent in a pressure stream of gases through the conduits. The first and second reagent supply device provides the reagent which is injected into a pressure stream by the control device. Each of the flows through the conduits are regulated independent of one another in order to prevent clogging of the exit ports of the conduits while eliminating any splash and turbulence.
