Abstract
192,150. Ballantine, W. B. Oct. 25, 1921. Alloys.-Low-carbon ferro-chromium alloys are made by heating in an electric furnace a mixture of chromite or other oxidized iron-chromium compound and an alkaline earth silicide such as calcium silicide. The alloy produced may be refined as described in Specifications 159,568 and 179,992. One or both of the electrodes of the furnace may be made of ferro-chromium; or, where a carbon electrode is employed, a layer of carbon-free material, such as broken slag, may be interposed between the electrode and the charge.
