摘要：
Reduction of the carbon content of ferro-alloys including stainless steel is effected by adding to the molten alloy a material more readily oxidizable than the alloy element and shattering a stream of the crude alloy by a jet of oxidizing gas, the temperature being thereby raised to a level at which carbon will be oxidized preferentially to the alloy element.
