Abstract
198,488. Mackenzie, R. S. March 22, 1922. No Patent granted (Sealing fee not paid). Alloys. - Chromium steel and chromium iron alloys are made by adding to a molten steel or iron bath, while continuing the heating of the receptacle containing it, a mixture of chromite and a reducing-agent comprising one or more metallic silicides, such as ferro-silicon or calcium silicide, and not containing carbon. Lime or fluorspar may be added, and the mixture may be briquetted with a binder such as sodium silicate or may be packed into thin iron receptacles. The briquettes or receptacles may be charged into the molten bath through an adjustable fireclay-covered pipe the lower end of which terminates a short distance above the surface of the slag. Reference has been directed by the Comptroller to Specifications 198,633 and 202,664.
