| Abstract: | The effect of GOR decarbonization and denitrification as well as the combined deoxidation of ferrosilicon and aluminum ingot on the smelting of American standard 321 stainless steel was studied by analyzing the industrial test of GOR. The process engineering and related consumption index of GOR smelting American standard 321 were discussed. The basic metallurgical principle of GOR smelting 321 was studied, and the effects of decarburization, chromium preservation, deoxidation, desulfurization and degassing were analyzed according to the smelting results. The results show that GOR has the conditions for smelting low carbon and low nitrogen 300 series stainless steel. Mass fraction of carbon and nitrogen in molten steel can be controlled within 0.015% by adjusting argon-oxygen ratio, and mass fraction of total oxygen and sulfur in molten steel can be controlled within 0.003% by appropriate deoxidation operation, which creates good conditions for subsequent LF titanium wire processing. |
