Abstract
513,853. Alloys. CLIMAX MOLYBDENUM CO. April 14, 1938, No. 11565. Convention date, March 11. [Class 82 (i)] Tungsten is incorporated in steel by adding a self-reducing mechanical mixture consisting of tungstic oxide and a carbonaceous binder, e.g., still-pitch, to a molten ferrous alloy. The mixture, which may comprise nine parts of oxide and one of binder, may be added in the form of a briquette, and if desired, together with a quantity of ferro-tungsten. The bath is agitated and freed from hydrogen by the resulting production of carbon dioxide ; impurities are oxidized by the tungstic oxide and ingredients such as vanadium, chromium and silicon oxidized in this way, which it is desired to retain, are recovered by a reducing-agent such as ferro-silicon.
