Abstract: Molten iron containing chromium is refined by oxygen being blown onto the surface of the molten metal while said surface is being kept free of slag; at the same time as the oxygen is being blown onto the surface of the metal, a molten iron is also subjected to vigorous stirring or agitation.

Abstract translation: 含有铬的熔融铁被氧气吹送到熔融金属的表面而被精炼，同时所述表面保持无渣; 同时当氧气吹到金属表面上时，铁水也受到剧烈的搅拌或搅拌。

Abstract: A molten metal in a container is treated with a gas. The gas is supplied through an opening, preferably a slit-shaped opening, in the bottom or lower wall portion of the container, thus forming bubbles which ascend in the molten metal. The container is rotated or shaken or vibrated so that a flow is created in the molten metal relative to the wall of the container. The molten metal thus passing by the gas supply opening removes the gas bubbles from the gas supply opening before the bubbles have had time to grow to the size they would have reached in stagnant molten metal.

Abstract translation: 用气体处理容器中的熔融金属。 气体通过容器底部或下壁部分中的开口，优选狭缝形开口供应，从而形成在熔融金属中上升的气泡。 容器旋转或摇动或振动，使得熔融金属相对于容器壁产生流动。 因此，通过气体供给开口的熔融金属在气泡已经有时间增长到在停滞的熔融金属中将达到的尺寸之前，从气体供应开口排出气泡。
