Abstract
PURPOSE: To easily obtain a high chromium alloy using nonstandardized ferrochromium by adding a predetermined Al-Cr-Fe alloy as a reducing agent to molten chromium oxide-contg. slag. followed by stirring.
CONSTITUTION: To molten chromium oxide-contg. slag is added an Al-Cr-Fe alloy, as a reducing agent, manufactured by melting metallic Al and a nonstandardized Fe-Cr alloy. They are then stirred to obtain a high chromium alloy. For example, in case a high chromium alloy manufactured contg. 80W95% Cr, chromium ore 1 and quick lime 2 are mixed and melted in an electric furnace to obtain chromium slag 3. On the other hand, Fe-Cr 5 is added to Al 4 melted in an induction melting furnace, cast, and crushed to manufacture Al-Cr-Fe alloy reducing agent 6. This agent is added to slag 3 and reacted to obtain high chromium slag 8 and by-product metal 9. Al-Cr-Fe alloy reducing agent 10 is then added to slag 8 and reacted to obtain high chromium alloy 12 and slag 13.
