Abstract

159,568. Ballantine, W. B. Nov. 24. 1919. Alloys; thermo-aluminic and like mixtures and metal-extracting processes.-Low-carbon ferrochromium is made by subjecting crude ferrochromium to the action of an oxidizing blast in a converter. A thermo-reduction mixture, preferably in the form of blocks or masses, and containing chromite or a pure chromium compound orboth, may be added to the molten alloy before or after tapping from the converter for the purpose of adjusting the chromium content. The crude ferro-chromium may be first prepared by the reduction of chromite in an electric furnace, steel scrap or the like forming part of the charge, or by a thermo-reduction process in which a cheap reducing agent such as calcium carbide is used. In some cases, mild basic steel may be added to the crude material prior to treatment in the converter. Reference has been directed by the Comptroller to Specification 145,709.
