Abstract

1,219,674. Producing iron powder. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Sept.30, 1969 [Oct. 7,1968], No.47530/68. Heading C7D. Iron powder suitable for use in powder metallurgy is produced by reducing an oxide produced by the Aman process (roasting of iron chloride residues from HC1 pickling baths) in a reducing atmosphere at elevated temperature under conditions which give rise to partially sintered iron powder. A thin bed of oxide may be reduced in a continuous band furnace by hydrogen at 860‹-1200‹C, and the initial oxide preferably has a density of at least 0.65 with at least 75% of the particles between 100 and 350 BSS mesh. Sulphur may be added to the ore as such or as ferric sulphate to facilitate reduction. The product may be ball-milled to increase its density.
