Abstract

211,210. Hamilton, W. B., and Evans, T. A. Nov. 14, 1922. Alloys.-In a process of the kind described in Specification 174,271 for making iron and steel alloys containing chromium, and adapted for the utilization of iron-chromium ores containing substantial proportions of silica, about 20 per cent of the ore is added to a reception slag before the addition to the bath of the remainder of the ore and an amount of aluminum or other reducing agent in excess of that chemically equivalent to the reducible metallic oxides in the whole of the ore. The process is preferably carried out in an electric furnace which is charged with iron or steel or molten metal, the slag first formed being removed. The reception slag is then made by charging in lime, fluorspar, and a portion of the ore as referred to above, and, after such slag is sufficiently fluid, the aluminium and the remainder of the chromite are added either separately or in admixture. The reducing agent must be of such a nature that it reduces to a substantial extent silica contained in the ore.
