ABSTRACT:
This invention provides a method of reducing the content of a particular substance in molten steel, which includes placing the molten steel and a quantity of slag in a refractory container, submerging a refractory rotor into the molten steel beneath the slag, and rotating the rotor about its axis at a speed sufficient to draw part of the interface between the molten steel and the slag down to the upper face of the rotor. The rotor has downwardly and outwardly extending passageways through which the slag is pumped during rotation of the rotor, whereby the interface area between the slag and the molten steel is increased. During such rotation, the slag is treated from above with a material which preferentially reacts with said particular substance to remove the same from the molten steel. The said material becomes a part of the slag and is brought into contact with the molten steel by virtue of the slag being pumped through the molten steel and by virtue of the total interface being in motion and of increased area.
