Abstract

1420597 Making stainless steel BRITISH STEEL CORP 24 Jan 1973 [27 Jan 1972] 3885/72 Headings C7D and C7X Stainless steel is produced by melting together in an L.D. converter, a ferrous metal (e.g. pig iron) and ferrochrome containing carbon, refining the melt by injecting an oxygen-containing blast and then adding ferrosilicon to the slag formed on the melt. The blast may be of oxygen or may be mixed with fuel oil. The product melt may be cast or may be atomized with nitrogen jets prior to quenching into water, which preferably contains a corrosion inhibitor (e.g. tri-ethanolamine). The refining stage may be effected in three stages as in Specification 1209987.
