Abstract

PURPOSE:To economically refine the title steel in a single furnace while preventing oxidation of Cr by desiliconizing and dephosphorizing hot iron bofore being charged into a converter with a slag making material and O2 gas, followed by decarburization refining with a high Cr alloy in an oxygen converter, and reduction of Cr and desulfurization with a Si source and a suitable amt. of a lime type slag making material.
