摘要： A method of refining a molten metal or a molten alloy through degassing, wherein a gas is blown into a molten metal or a molten alloy contained within a refining container, while stirring by utilizing an electromagnetic force, to superimpose the blown gas onto a molten metal or a molten alloy, and the stirring by an electromagnetic force, to thereby refine the blown gas, and at the same time, increase the residence time of the blown gas in the molten metal or molten alloy bath and homogeneously disperse the blown gas in the molten metal or molten alloy bath.

摘要： A carbon-unsaturated molten metal or molten alloy containing elements more oxidizable than iron such as chromium and silicon is dephosphorized by addition of a flux composition comprising calcium carbide and a halide of alkali earth metal such as calcium fluoride in a non-oxidizing atmosphere, and thereafter the slag as a by-product is stabilized against formation of undesirable gases. This method when employed in refining ferrochromium or crude stainless steel makes feasible dephosphorization, and it is particularly suited for economical production of low phosphorus stainless steel.
摘要翻译： 通过在非氧化性气氛中加入包含碳化钙和碱土金属卤化物如氟化钙的助熔剂组合物，含有比铁，硅和硅更可氧化的元素的碳 - 不饱和熔融金属或熔融合金脱磷， 此后，作为副产物的炉渣被稳定以防止不期望的气体的形成。 该方法用于精炼铬铁或粗不锈钢时，可以实现脱磷，特别适用于经济生产低磷不锈钢。
