<p>A system and method is provided for refining molten metal in a top-blown vessel, particularly, by removal of the carbon content. The system includes various means for selecting, regulating the composition and controlling the rate of flow of the top-blown gases. The system further includes various means for introducing an inert gas from beneath the molten bath surface during top blowing and regulating the composition and controlling the rate of flow of the inert gas as a function of the top-blown gas composition and flow rate. A method for introducing the gases is also provided.</p> |
